Abstract
Genome editing is a promising method for simultaneously mutagenizing homoeologs in the three subgenomes of wheat (Triticum aestivum L.). However, the mutation rate via genome editing must be improved in order to analyze gene function and to quickly modify agronomic traits in wheat. Here, we examined the Cas9-induced mutation rates in wheat plants using two promoters for single guide RNA (sgRNA) expression and applying heat treatment during Agrobacterium tumefaciens-mediated transformation. Using the TaU6 promoter instead of the OsU6 promoter from rice (Oryza sativa L.) to drive sgRNA expression greatly improved the Cas9-induced mutation rate. Moreover, a heat treatment of 30°C for 1 day during tissue culture increased the Cas9-induced mutation rate and the variety of mutations obtained compared to tissue culture at the normal temperature (25°C). The same heat treatment did not affect the regeneration rates of transgenic plants but tended to increase the number of transgene integration sites in each transgenic plant. These results lay the foundation for improving the Cas9-induced mutation rate in wheat to enhance research on gene function and crop improvement.

Abstract
Barley double mutants in two genes involved in starch granule morphology, HvFLO6 and HvISA1, had impaired starch accumulation and higher grain sugar levels than either single mutant. Starch is a biologically and commercially important glucose polymer synthesized by plants as semicrystalline starch granules (SGs). Because SG morphology affects starch properties, mutants with altered SG morphology may be useful in breeding crops with desirable starch properties, including potentially novel properties. In this study, we employed a simple screen for mutants with altered SG morphology in barley (Hordeum vulgare). We isolated mutants that formed compound SGs together with the normal simple SGs in the endosperm and found that they were allelic mutants of the starch biosynthesis genes ISOAMYLASE1 (HvISA1) and FLOURY ENDOSPERM 6 (HvFLO6), encoding starch debranching enzyme and CARBOHYDRATE-BINDING MODULE 48-containing protein, respectively. We generated the hvflo6 hvisa1 double mutant and showed that it had significantly reduced starch biosynthesis and developed shrunken grains. In contrast to starch, soluble α-glucan, phytoglycogen, and sugars accumulated to higher levels in the double mutant than in the single mutants. In addition, the double mutants showed defects in SG morphology in the endosperm and in the pollen. This novel genetic interaction suggests that hvflo6 acts as an enhancer of the sugary phenotype caused by hvisa1 mutation.

Abstract
Many aphid-borne viruses are important pathogens that affect wheat crops worldwide. An aphid-transmitted closterovirus named wheat yellow leaf virus (WYLV) was found to have infected wheat plants in Japan in the 1970s; however, since then, its viral genome sequence and occurrence in the field have not been investigated. We observed yellowing leaves in the 2018/2019 winter wheat-growing season in an experimental field in Japan where WYLV was detected five decades ago. A virome analysis of those yellow leaf samples lead to the discovery of a closterovirus together with a luteovirus (barley yellow dwarf virus PAV variant IIIa). The complete genomic sequence of this closterovirus, named wheat closterovirus 1 isolate WL19a (WhCV1-WL19a), consisted of 15,452 nucleotides harboring nine open reading frames. Additionally, we identified another WhCV1 isolate, WL20, in a wheat sample from the winter wheat-growing season of 2019/2020. A transmission test indicated that WhCV1-WL20 was able to form typical filamentous particles and transmissible by oat bird-cherry aphid (Rhopalosiphum pad). Sequence and phylogenetic analyses showed that WhCV1 was distantly related to members of the genus Closterovirus (family Closteroviridae), suggesting that the virus represents a novel species in the genus. Furthermore, the characterization of WhCV1-WL19a-derived small RNAs using high-throughput sequencing revealed highly abundant 22-nt-class small RNAs potentially derived from the 3′-terminal end of the WhCV1 negative-strand genomic RNA, indicating that this terminal end of the WhCV1 genome is likely particularly targeted for the synthesis of viral small RNAs in wheat plants. Our results provide further knowledge on closterovirus diversity and pathogenicity and suggest that the impact of WhCV1 on wheat production warrants further investigations.

Abstract
Barley (Hordeum vulgare) is the fourth most highly produced cereal in the world after wheat, rice and maize and is mainly utilized as malts and for animal feed. Barley, a model crop of the tribe Triticeae, is important in comparative analyses of Poaceae. However, molecular understanding about the developmental processes is limited in barley. Our previous work characterized one of two WUSCHEL-RELATED HOMEOBOX 3 (WOX3) genes present in the barley genome: NARROW LEAFED DWARF1 (NLD1). We demonstrated that NLD1 plays a pivotal role in the development of lateral organs. In the present study, we describe a bifurcated palea (bip) mutant of barley focusing on flower and leaf phenotypes. The palea in the bip mutant was split into two and develop towards inside the lemma surrounding the carpels and anthers. The bip mutant is devoid of lodicules, which develop in a pair at the base of the stamen within the lemma in normal barley. bip also exhibited malformations in leaves, such as narrow leaf due to underdeveloped leaf-blade width, and reduced trichome density. Map-based cloning and expression analysis indicated that BIP is identical to another barley WOX3 gene, named HvWOX3. The bip nld1 double mutant presented a more severe reduction in leaf-blade width and number of trichomes. By comparing the phenotypes and gene expression patterns of various WOX3 mutants, we concluded that leaf bilateral outgrowth and trichome development are promoted by both NLD1 and HvWOX3, but that HvWOX3 serves unique and pivotal functions in barley development that differ from those of NLD1.

Abstract
Grains are the major sink of phosphorus (P) in cereal crops, accounting for 60-85% of total plant P, but the mechanisms underlying P loading into the grains are poorly understood. We functionally characterized a transporter gene required for the distribution of P to the grains in barley (Hordeum vulgare), HvSPDT (SULTR-like phosphorus distribution transporter). HvSPDT encoded a plasma membrane-localized Pi/H+ cotransporter. It was mainly expressed in the nodes at both the vegetative and reproductive stages. Furthermore, its expression was induced by inorganic phosphate (Pi) deficiency. In the nodes, HvSPDT was expressed in both the xylem and phloem region of enlarged and diffuse vascular bundles. Knockout of HvSPDT decreased the distribution of P to new leaves, but increased the distribution to old leaves at the vegetative growth stage under low P supply. However, knockout of HvSPDT did not alter the redistribution of P from old to young organs. At the reproductive stage, knockout of HvSPDT significantly decreased P allocation to the grains, resulting in a considerable reduction in grain yield, especially under P-limited conditions. Our results indicate that node-based HvSPDT plays a crucial role in loading P into barley grains through preferentially distributing P from the xylem and further to the phloem.

Abstract
High humidity during harvest season often causes pre-harvest sprouting in barley (Hordeum vulgare). Prolonged grain dormancy prevents pre-harvest sprouting; however, extended dormancy can interfere with malt production and uniform germination upon sowing. In this study, we used Cas9-induced targeted mutagenesis to create single and double mutants in QTL FOR SEED DORMANCY 1 (Qsd1) and Qsd2 in the same genetic background. We performed germination assays in independent qsd1 and qsd2 single mutants, as well as in two double mutants, which revealed a strong repression of germination in the mutants. These results demonstrated that normal early grain germination requires both Qsd1 and Qsd2 function. However, germination of qsd1 was promoted by treatment with 3% hydrogen peroxide, supporting the notion that the mutants exhibit delayed germination. Likewise, exposure to cold temperatures largely alleviated the block of germination in the single and double mutants. Notably, qsd1 mutants partially suppress the long dormancy phenotype of qsd2, while qsd2 mutant grains failed to germinate in the light, but not in the dark. Consistent with the delay in germination, abscisic acid accumulated in all mutants relative to the wild type, but abscisic acid levels cannot maintain long-term dormancy and only delay germination. Elucidation of mutant allele interactions, such as those shown in this study, are important for fine-tuning traits that will lead to the design of grain dormancy through combinations of mutant alleles. Thus, these mutants will provide the necessary germplasm to study grain dormancy and germination in barley.

Abstract
The recent advent of customizable endonucleases has led to remarkable advances in genetic engineering, as these molecular scissors allow for the targeted introduction of mutations or even precisely predefined genetic modifications into virtually any genomic target site of choice. Thanks to its unprecedented precision, efficiency, and functional versatility, this technology, commonly referred to as genome editing, has become an effective force not only in basic research devoted to the elucidation of gene function, but also for knowledge-based improvement of crop traits. Among the different platforms currently available for site-directed genome modifications, RNA-guided clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) endonucleases have proven to be the most powerful. This review provides an application-oriented overview of the development of customizable endonucleases, current approaches to cereal crop breeding, and future opportunities in this field.

Abstract
Loss-of-function mutation of the MILDEW RESISTANCE LOCUS O (Mlo) gene confers durable and broad-spectrum resistance to powdery mildew fungi in various plants, including barley. In combination with the intracellular nucleotide-binding domain and leucine-rich repeat receptor (NLR) genes, which confer the race-specific resistance, the mlo alleles have long been used in barley breeding as genetic resources that confer robust non-race-specific resistance. However, a Japanese Blumeria graminis f. sp. hordei isolate, RACE1, has been reported to have the potential to overcome partially the mlo-mediated penetration resistance, although this is yet uncertain because the putative effects of NLR genes in the tested accessions have not been ruled out. In this study, we examined the reproducibility of the earlier report and found that the infectious ability of RACE1, which partially overcomes the mlo-mediated resistance, is only exerted in the absence of NLR genes recognizing RACE1. Furthermore, using the transient-induced gene silencing technique, we demonstrated that RACE1 can partially overcome the resistance in the host cells with suppressed MLO expression but not in plants possessing the null mutant allele mlo-5.

Abstract
Yellow mosaic disease in winter wheat is usually attributed to the infection by bymoviruses or furoviruses; however, there is still limited information on whether other viral agents are also associated with this disease. To investigate the wheat viromes associated with yellow mosaic disease, we carried out de novo RNA sequencing (RNA-seq) analyses of symptomatic and asymptomatic wheat-leaf samples obtained from a field in Hokkaido, Japan, in 2018 and 2019. The analyses revealed the infection by a novel betaflexivirus, which tentatively named wheat virus Q (WVQ), together with wheat yellow mosaic virus (WYMV, a bymovirus) and northern cereal mosaic virus (a cytorhabdovirus). Basic local alignment search tool (BLAST) analyses showed that the WVQ strains (of which there are at least three) were related to the members of the genus Foveavirus in the subfamily Quinvirinae (family Betaflexiviridae). In the phylogenetic tree, they form a clade distant from that of the foveaviruses, suggesting that WVQ is a member of a novel genus in the Quinvirinae. Laboratory tests confirmed that WVQ, like WYMV, is potentially transmitted through the soil to wheat plants. WVQ was also found to infect rye plants grown in the same field. Moreover, WVQ-derived small interfering RNAs accumulated in the infected wheat plants, indicating that WVQ infection induces antiviral RNA silencing responses. Given its common coexistence with WYMV, the impact of WVQ infection on yellow mosaic disease in the field warrants detailed investigation.

Abstract
Limitations for the application of genome editing technologies on elite wheat (Triticum aestivum L.) varieties are mainly due to the dependency on in vitro culture and regeneration capabilities. Recently, we developed an in planta particle bombardment (iPB) method which has increased process efficiency since no culture steps are required to create stably genome-edited wheat plants. Here, we report the application of the iPB method to commercially relevant Japanese elite wheat varieties. The biolistic delivery of gold particles coated with plasmids expressing CRISPR/Cas9 components designed to target TaQsd1 were bombarded into the embryos of imbibed seeds with their shoot apical meristem (SAM) exposed. Mutations in the target gene were subsequently analyzed within flag leaf tissue by using cleaved amplified polymorphic sequence (CAPS) analysis. A total of 9/358 (2.51%) of the bombarded plants (cv. "Haruyokoi," spring type) carried mutant alleles in the tissue. Due to the chimeric nature of the T0 plants, only six of them were inherited to the next (T1) generation. Genotypic analysis of the T2 plants revealed a single triple-recessive homozygous mutant of the TaQsd1 gene. Compared to wild type, the homozygous mutant exhibited a 7 days delay in the time required for 50% seed germination. The iPB method was also applied to two elite winter cultivars, "Yumechikara" and "Kitanokaori," which resulted in successful genome editing at slightly lower efficiencies as compared to "Haruyokoi." Taken together, this report demonstrates that the in planta genome editing method through SAM bombardment can be applicable to elite wheat varieties that are otherwise reluctant to callus culture.

Abstract
In plant research and breeding, haploid technology is employed upon crossing, induced mutagenesis or genetic engineering to generate populations of meiotic recombinants that are themselves genetically fixed. Thanks to the speed and efficiency in producing true-breeding lines, haploid technology has become a major driver of modern crop improvement. In the present study, we used embryogenic pollen cultures of winter barley ( Hordeum vulgare ) for Cas9 endonuclease-mediated targeted mutagenesis in haploid cells, which facilitates the generation of homozygous primary mutant plants. To this end, microspores were extracted from immature anthers, induced to undergo cell proliferation and embryogenic development in vitro, and were then inoculated with Agrobacterium for the delivery of T-DNAs comprising expression units for Cas9 endonuclease and target gene-specific guide RNAs (gRNAs). Amongst the regenerated plantlets, mutants were identified by PCR amplification of the target regions followed by sequencing of the amplicons. This approach also enabled us to discriminate between homozygous and heterozygous or chimeric mutants. The heritability of induced mutations and their homozygous state were experimentally confirmed by progeny analyses. The major advantage of the method lies in the preferential production of genetically fixed primary mutants, which facilitates immediate phenotypic analyses and, relying on that, a particularly efficient preselection of valuable lines for detailed investigations using their progenies.

Abstract
Common wheat has three sets of sub-genomes, making mutations difficult to observe, especially for traits controlled by recessive genes. Here, we produced hexaploid wheat lines with loss of function of homeoalleles of Qsd1, which controls seed dormancy in barley, by Agrobacterium-mediated CRISPR/Cas9. Of the eight transformed wheat events produced, three independent events carrying multiple mutations in wheat Qsd1 homeoalleles were obtained. Notably, one line had mutations in every homeoallele. We crossed this plant with wild-type cultivar Fielder to generate a transgene-free triple-recessive mutant, as revealed by Mendelian segregation. The mutant showed a significantly longer seed dormancy period than wild-type, which may result in reduced pre-harvest sprouting of grains on spikes. PCR, southern blotting, and whole-genome shotgun sequencing revealed that this segregant lacked transgenes in its genomic sequence. This technique serves as a model for trait improvement in wheat, particularly for genetically recessive traits, based on locus information from diploid barley.

Abstract
Barley is the fourth most produced cereal crop in the world and one of the major dietary sources of cadmium (Cd), which poses serious threats to human health. Here, we identify a gene that encodes a P-type heavy metal ATPase 3 (HvHMA3) responsible for grain Cd accumulation in barley. HvHMA3 from the high Cd barley variety Haruna Nijo in Japan and the low Cd variety BCS318 in Afghanistan shared 97% identity at the amino acid level. In addition, the HvHMA3 from both varieties showed similar transport activity for Cd and the same subcellular localization at the tonoplast. However, the expression of HvHMA3 was double in BCS318 than in Haruna Nijo. A 3.3-kilobase Sukkula-like transposable element was found to be inserted upstream of the gene in the low Cd variety, which functioned as a promoter and enhanced the expression of HvHMA3. Introgression of this insertion to an elite barley cultivar through backcrossing resulted in decreased Cd accumulation in the grain grown in Cd-contaminated soil without yield penalty. The decreased Cd accumulation resulting from the insertion was also found in some other barley landraces in the world. Our results indicate that insertion of the Sukkula-like transposable element plays an important role in upregulating HvHMA3 expression.

Abstract
Aphids (order Hemiptera) are important insect pests of crops and are also vectors of many plant viruses. However, little is known about aphid-infecting viruses, particularly their diversity and relationship to plant viruses. To investigate the aphid viromes, we performed deep sequencing analyses of the aphid transcriptomes from infested barley plants in a field in Japan. We discovered virus-like sequences related to nege/kita-, flavi-, tombus-, phenui-, mononega-, narna-, chryso-, partiti-, and luteoviruses. Using RT-PCR and sequence analyses, we determined almost complete sequences of seven nege/kitavirus-like virus genomes; one of which was a variant of the Wuhan house centipede virus (WHCV-1). The other six seem to belong to four novel viruses distantly related to Wuhan insect virus 9 (WhIV-9) or Hubei nege-like virus 4 (HVLV-4). We designated the four viruses as barley aphid RNA virus 1 to 4 (BARV-1 to -4). Moreover, some nege/kitavirus-like sequences were found by searches on the transcriptome shotgun assembly (TSA) libraries of arthropods and plants. Phylogenetic analyses showed that BARV-1 forms a clade with WHCV-1 and HVLV-4, whereas BARV-2 to -4 clustered with WhIV-9 and an aphid virus, Aphis glycines virus 3. Both virus groups (tentatively designated as Centivirus and Aphiglyvirus, respectively), together with arthropod virus-like TSAs, fill the phylogenetic gaps between the negeviruses and kitaviruses lineages. We also characterized the flavi/jingmen-like and tombus-like virus sequences as well as other RNA viruses, including six putative novel viruses, designated as barley aphid RNA viruses 5 to 10. Interestingly, we also discovered that some aphid-associated viruses, including nege/kita-like viruses, were present in different aphid species, raising a speculation that these viruses might be distributed across different aphid species with plants being the reservoirs. This study provides novel information on the diversity and spread of nege/kitavirus-related viruses and other RNA viruses that are associated with aphids.

Abstract
Ferulate 5-hydroxylase (F5H) catalyses the hydroxylation of coniferyl alcohol and coniferaldehyde for the biosynthesis of syringyl (S) lignin in angiosperms. However, the coordinated effects of F5H with caffeic acid O-methyltransferase (COMT) on the metabolic flux towards S units are largely unknown. We concomitantly regulated F5H expression in COMT-down-regulated transgenic switchgrass (Panicum virgatum L.) lines and studied the coordination of F5H and COMT in lignin biosynthesis. Down-regulation of F5H in COMT-RNAi transgenic switchgrass plants further impeded S lignin biosynthesis and, consequently, increased guaiacyl (G) units and reduced 5-OH G units. Conversely, overexpression of F5H in COMT-RNAi transgenic plants reduced G units and increased 5-OH units, whereas the deficiency of S lignin biosynthesis was partially compensated or fully restored, depending on the extent of COMT down-regulation in switchgrass. Moreover, simultaneous regulation of F5H and COMT expression had different effects on cell wall digestibility of switchgrass without biomass loss. Our results indicate that up-regulation and down-regulation of F5H expression, respectively, have antagonistic and synergistic effects on the reduction in S lignin resulting from COMT suppression. The coordinated effects between lignin genes should be taken into account in future studies aimed at cell wall bioengineering.

Abstract
The plant pathogen Agrobacterium tumefaciens infects plants and introduces the transferred-DNA (T-DNA) region of the Ti-plasmid into nuclear DNA of host plants to induce the formation of tumors (crown galls). The T-DNA region carries iaaM and iaaH genes for synthesis of the plant hormone auxin, indole-3-acetic acid (IAA). It has been demonstrated that the iaaM gene encodes a tryptophan 2-monooxygenase which catalyzes the conversion of tryptophan to indole-3-acetamide (IAM), and the iaaH gene encodes an amidase for subsequent conversion of IAM to IAA. In this article, we demonstrate that A. tumefaciens enhances the production of both IAA and phenylacetic acid (PAA), another auxin which does not show polar transport characteristics, in the formation of crown galls. Using liquid chromatography-tandem mass spectroscopy, we found that the endogenous levels of phenylacetamide (PAM) and PAA metabolites, as well as IAM and IAA metabolites, are remarkably increased in crown galls formed on the stem of tomato plants, implying that two distinct auxins are simultaneously synthesized via the IaaM-IaaH pathway. Moreover, we found that the induction of the iaaM gene dramatically elevated the levels of PAM, PAA and its metabolites, along with IAM, IAA and its metabolites, in Arabidopsis and barley. From these results, we conclude that A. tumefaciens enhances biosynthesis of two distinct auxins in the formation of crown galls.

Abstract
Enhancing salt stress tolerance is a key strategy for increasing global food production. We previously found that long-term salinity stress significantly reduced grain fertility in the salt-sensitive barley (Hordeum vulgare) accession, 'OUC613', but not in the salt-tolerant accession, 'OUE812', resulting in large differences in grain yield. Here, we examined the underlying causes of the difference in grain fertility between these accessions under long-term treatment with 150 or 200 mM NaCl from the seedling stage to harvest and identified quantitative trait loci (QTLs) for maintaining grain fertility. In an artificial pollination experiment of the two accessions, grain fertility was significantly reduced only in OUC613 plants produced using pollen from plants grown under NaCl stress, suggesting that the low grain fertility of OUC613 was mainly due to reduced pollen fertility. Using QTL-seq combined with exome-capture sequencing and composite interval mapping of recombinant inbred lines derived from a cross between OUE812 and OUC613, we identified a QTL (qRP-2Hb) for grain fertility on chromosome 2H. The QTL region includes two genes encoding an F-box protein and a TIFY protein that are associated with male sterility, highlighting the importance of this region for maintaining grain fertility under salt stress.

Abstract
Global transcriptome studies demonstrated the existence of unique plant responses under combined stress which are otherwise not seen during individual stresses. In order to combat combined stress plants use signaling pathways and 'cross talk' mediated by hormones involved in stress and growth related processes. However, interactions among hormones' pathways in combined stressed plants are not yet known. Here we studied dynamics of different hormones under individual and combined drought and pathogen infection in Arabidopsis thaliana by liquid chromatography-mass spectrometry (LC-MS) based profiling. Our results revealed abscisic acid (ABA) and salicylic acid (SA) as key regulators under individual drought and pathogen stress respectively. Under combined drought and host pathogen stress (DH) we observed non-induced levels of ABA with an upsurge in SA and jasmonic acid (JA) concentrations, underscoring their role in basal tolerance against host pathogen. Under a non-host pathogen interaction with drought (DNH) stressed plants, ABA, SA and JA profiles were similar to those under DH or non-host pathogen alone. We propose that plants use SA/JA dependent signaling during DH stress which antagonize ABA biosynthesis and signaling pathways during early stage of stress. The study provides insights into hormone modulation at different time points during combined stress.

Abstract
The genetic substitution of transformation amenability alleles from 'Golden Promise' can facilitate the development of transformation-efficient lines from recalcitrant barley cultivars. Barley (Hordeum vulgare) cv. 'Golden Promise' is one of the most useful and well-studied cultivars for genetic manipulation. In a previous report, we identified several transformation amenability (TFA) loci responsible for Agrobacterium-mediated transformation using the F2 generation of immature embryos, derived from 'Haruna Nijo' × 'Golden Promise,' as explants. In this report, we describe higher density mapping of these TFA regions with additional SNP markers using the same transgenic plants. To demonstrate the robustness of transformability alleles at the TFA loci, we genotyped 202 doubled haploid progeny from the cross 'Golden Promise' × 'Full Pint.' Based on SNP genotype, we selected lines having 'Golden Promise' alleles at TFA loci and used them for transformation. Of the successfully transformed lines, DH120366 came the closest to achieving a level of transformation efficiency comparable to 'Golden Promise.' The results validate that the genetic substitution of TFA alleles from 'Golden Promise' can facilitate the development of transformation-efficient lines from recalcitrant barley cultivars.

Abstract
Background QTL-seq, in combination with bulked segregant analysis and next-generation sequencing (NGS), is used to identify loci in small plant genomes, but is technically challenging to perform in species with large genomes, such as barley. A combination of exome sequencing and QTL-seq (exome QTL-seq) was used to map the mono-factorial Mendelian locus black lemma and pericarp (Blp) and QTLs for resistance to net blotch disease, a common disease of barley caused by the fungus Pyrenophora teres, which segregated in a population of 100 doubled haploid barley lines. Methods The provisional exome sequences were prepared by ordering the loci of expressed genes based on the genome information and concatenating genes with intervals of 200-bp spacer "N" for each chromosome. The QTL-seq pipeline was used to analyze short reads from the exome-captured library. Results In this study, short NGS reads of bulked total DNA samples from segregants with extreme trait values were subjected to exome capture, and the resulting exome sequences were aligned to the reference genome. SNP allele frequencies were compared to identify the locations of genes/QTLs responsible for the trait value differences between lines. For both objective traits examined, exome QTL-seq identified the monogenic Mendelian locus and associated QTLs. These findings were validated using conventional mapping approaches. Conclusions Exome QTL-seq broadens the utility of NGS-based gene/QTL mapping in organisms with large genomes.

Abstract
BACKGROUND The mission of the BioEnergy Science Center (BESC) was to enable efficient lignocellulosic-based biofuel production. One BESC goal was to decrease poplar and switchgrass biomass recalcitrance to biofuel conversion while not affecting plant growth. A transformation pipeline (TP), to express transgenes or transgene fragments (constructs) in these feedstocks with the goal of understanding and decreasing recalcitrance, was considered essential for this goal. Centralized data storage for access by BESC members and later the public also was essential. RESULTS A BESC committee was established to codify procedures to evaluate and accept genes into the TP. A laboratory information management system (LIMS) was organized to catalog constructs, plant lines and results from their analyses. One hundred twenty-eight constructs were accepted into the TP for expression in switchgrass in the first 5 years of BESC. Here we provide information on 53 of these constructs and the BESC TP process. Eleven of the constructs could not be cloned into an expression vector for transformation. Of the remaining constructs, 22 modified expression of the gene target. Transgenic lines representing some constructs displayed decreased recalcitrance in the field and publications describing these results are tabulated here. Transcript levels of target genes and detailed wall analyses from transgenic lines expressing six additional tabulated constructs aimed toward modifying expression of genes associated with wall structure (xyloglucan and lignin components) are provided. Altered expression of xyloglucan endotransglucosylase/hydrolases did not modify lignin content in transgenic plants. Simultaneous silencing of two hydroxycinnamoyl CoA:shikimate hydroxycinnamoyl transferases was necessary to decrease G and S lignin monomer and total lignin contents, but this reduced plant growth. CONCLUSIONS A TP to produce plants with decreased recalcitrance and a LIMS for data compilation from these plants were created. While many genes accepted into the TP resulted in transgenic switchgrass without modified lignin or biomass content, a group of genes with potential to improve lignocellulosic biofuel yields was identified. Results from transgenic lines targeting xyloglucan and lignin structure provide examples of the types of information available on switchgrass lines produced within BESC. This report supplies useful information when developing coordinated, large-scale, multi-institutional reverse genetic pipelines to improve crop traits.

Abstract
Different plant cultivars of the same genus and species can exhibit vastly different genetic transformation efficiencies. However, the genetic factors underlying these differences in transformation rate remain largely unknown. In barley, 'Golden Promise' is one of a few cultivars reliable for Agrobacterium-mediated transformation. By contrast, cultivar 'Haruna Nijo' is recalcitrant to genetic transformation. We identified genomic regions of barley important for successful transformation with Agrobacterium, utilizing the 'Haruna Nijo' × 'Golden Promise' F2 generation and genotyping by 124 genome-wide SNP markers. We observed significant segregation distortions of these markers from the expected 1:2:1 ratio toward the 'Golden Promise'-type in regions of chromosomes 2H and 3H, indicating that the alleles of 'Golden Promise' in these regions might contribute to transformation efficiency. The same regions, which we termed Transformation Amenability (TFA) regions, were also conserved in transgenic F2 plants generated from a 'Morex' × 'Golden Promise' cross. The genomic regions identified herein likely include necessary factors for Agrobacterium-mediated transformation in barley. The potential to introduce these loci into any haplotype of barley opens the door to increasing the efficiency of transformation for target alleles into any haplotype of barley by the TFA-based methods proposed in this report.

Abstract
Background Sequencing analysis of mitochondrial genomes is important for understanding the evolution and genome structures of various plant species. Barley is a self-pollinated diploid plant with seven chromosomes comprising a large haploid genome of 5.1 Gbp. Wild barley (Hordeum vulgare ssp. spontaneum) and cultivated barley (H. vulgare ssp. vulgare) have cross compatibility and closely related genomes, although a significant number of nucleotide polymorphisms have been reported between their genomes. Results We determined the complete nucleotide sequences of the mitochondrial genomes of wild and cultivated barley. Two independent circular maps of the 525,599 bp barley mitochondrial genome were constructed by de novo assembly of high-throughput sequencing reads of barley lines H602 and Haruna Nijo, with only three SNPs detected between haplotypes. These mitochondrial genomes contained 33 protein-coding genes, three ribosomal RNAs, 16 transfer RNAs, 188 new ORFs, six major repeat sequences and several types of transposable elements. Of the barley mitochondrial genome-encoded proteins, NAD6, NAD9 and RPS4 had unique structures among grass species. Conclusions The mitochondrial genome of barley was similar to those of other grass species in terms of gene content, but the configuration of the genes was highly differentiated from that of other grass species. Mitochondrial genome sequencing is essential for annotating the barley nuclear genome; our mitochondrial sequencing identified a significant number of fragmented mitochondrial sequences in the reported nuclear genome sequences. Little polymorphism was detected in the barley mitochondrial genome sequences, which should be explored further to elucidate the evolution of barley.

Abstract
Hordeum vulgare (barley) is an important agricultural crop worldwide. A simple and efficient transformation system is needed to analyze the functions of barley genes and generate lines with improved agronomic traits. Currently, Golden Promise and Igri are the most amenable barley cultivars for stable transformation. Here we evaluated the regeneration ratios and endogenous hormone levels of calli derived from various malting barley cultivars, including Golden Promise, Haruna Nijo, and Morex. We harvested samples not only from immature embryos, but also from different explants of juvenile plants, cotyledons, coleoptiles, and roots. The callus properties differed among genotypes and explant types. Calli derived from the immature embryos of Golden Promise, which showed the highest ratio of regeneration of green shoots, had the highest contents of indoleacetic acid, trans-zeatin, and cis-zeatin. By contrast, calli derived from the cotyledons of Morex and the immature embryos of Haruna Nijo had elevated levels of salicylic acid and abscisic acid, respectively. We thus propose that the former phytohormones are positively associated with the regeneration ability of callus but the later phytohormones are negatively associated.

Abstract
Background: Postoperative 1-year administration of S-1, an oral derivative of 5-fluorouracil (5-FU), was shown to be feasible in lung cancer. The 5-year survival rates of postoperative patients treated with S-1 adjuvant chemotherapy and the prognostic impact of clinicopathological factors were examined. Methods: The data of 50 patients with curatively resected pathological stage IB to IIIA non-small cell lung cancer, who were treated with S-1 postoperatively, were analyzed. The prognostic impacts of 22 clinicopathological factors including expressions of the 5-FU pathway enzymes were evaluated. A single-nucleotide polymorphism (SNP), i.e. 538G>A (rs17822931), of ABCC11/MRP8, which encodes a 5-FU excretion enzyme that is known as an earwax type determinant, was also evaluated. Results: The 5-year overall and relapse-free survival rates were 72.5 and 67.5%, respectively. A performance status ≥1, lymphatic vessel invasion, blood vessel invasion, and the A/A type of SNP538, which is responsible for the dry earwax type, were significantly associated with shorter relapse-free survivals. In 34 patients who showed a relative performance of 70% or more for chemotherapy, multivariate survival analysis indicated significant hazard ratios only for the A/A type of SNP538 (p = 0.007). Conclusions: S-1 has sufficient power as adjuvant chemotherapy. However, its effect might be small in the dry earwax type patient group in an adjuvant setting.

Abstract
It is necessary to overcome recalcitrance of the biomass to saccharification (sugar release) to make switchgrass (Panicum virgatum) economically viable as a feedstock for liquid biofuels. Lignin content correlates negatively with sugar release efficiency in switchgrass, but selecting the right gene candidates for engineering lignin biosynthesis in this tetraploid outcrossing species is not straightforward. To assist this endeavor, we have used an inducible switchgrass cell suspension system for studying lignin biosynthesis in response to exogenous brassinolide. By applying a combination of protein sequence phylogeny with whole-genome microarray analyses of induced cell cultures and developing stem internode sections, we have generated a list of candidate monolignol biosynthetic genes for switchgrass. Several genes that were strongly supported through our bioinformatics analysis as involved in lignin biosynthesis were confirmed by gene silencing studies, in which lignin levels were reduced as a result of targeting a single gene. However, candidate genes encoding enzymes involved in the early steps of the currently accepted monolignol biosynthesis pathway in dicots may have functionally redundant paralogues in switchgrass and therefore require further evaluation. This work provides a blueprint and resources for the systematic genome-wide study of the monolignol pathway in switchgrass, as well as other C4 monocot species.

Abstract
White clover (Trifolium repens L.) is an allotetraploid species (2n = 4X = 32) that is widely distributed in temperate regions and cultivated as a forage legume. In this study, we developed expressed sequence tag (EST)-derived simple sequence repeat (SSR) markers, constructed linkage maps, and performed comparative mapping with other legume species. A total of 7982 ESTs that could be assembled into 5400 contigs and 2582 singletons were generated. Using the EST sequences that were obtained, 1973 primer pairs to amplify EST-derived SSR markers were designed and used for linkage analysis of 188 F(1) progenies, which were generated by a cross between two Japanese plants, '273-7' and 'T17-349,' with previously published SSR markers. An integrated linkage map was constructed by combining parental-specific maps, which consisted of 1743 SSR loci on 16 homeologous linkage groups with a total length of 2511 cM. The primer sequences of the developed EST-SSR markers and their map positions are available on http://clovergarden.jp/. Linkage disequilibrium (LD) was observed on 9 of 16 linkage groups of a parental-specific map. The genome structures were compared among white clover, red clover (T. pratense L.), Medicago truncatula, and Lotus japonicus. Macrosynteny was observed across the four legume species. Surprisingly, the comparative genome structure between white clover and M. truncatula had a higher degree of conservation than that of the two clover species.

Abstract
BACKGROUND Oral adjuvant chemotherapy without hospitalization might reduce the physiological and psychological burden on patients if effectiveness could be guaranteed. We conducted a multicenter feasibility study using S-1, an oral derivative of 5-fluorouracil, as postoperative adjuvant chemotherapy in patients with curatively resected pathologically stage IB-IIIA non-small-cell lung cancer. PATIENTS AND METHODS Adjuvant chemotherapy comprised 8 courses (4-week administration, 2-week withdrawal) of S-1 at 80-120 mg per day. Fifty-one patients from 7 institutions were enrolled in this pilot study, from June 2005 to March 2007. The primary end point was the completion rate of scheduled adjuvant chemotherapy. Secondary end points were the incidence and grade of adverse reactions. RESULTS Fifty patients were eligible. The completion rate for the planned 8 courses of S-1 administration was 72.0% (36 patients). Total percentage administration amount was 71.1%. Grade 3 adverse reactions such as neutropenia (4.0%), anorexia (4.0%), thrombopenia (2.0%), anemia (2.0%), elevated total bilirubin (2.0%), hypokalemia (2.0%), nausea (2.0%), and diarrhea (2.0%) were observed, but no grade 4 adverse effects were encountered. Overall and relapse-free survival rates at 3 years were 87.7% and 69.4%, respectively. CONCLUSIONS Postoperative 1-year administration of S-1 seems feasible as oral adjuvant chemotherapy for lung cancer. The oral formulation and low incidence of adverse reactions permit treatment on an outpatient basis. The present study would be reasonable to follow up with a properly powered phase III trial.

Abstract
A well-saturated molecular linkage map is a prerequisite for modern plant breeding. Several genetic maps have been developed for soybean with various types of molecular markers. Simple sequence repeats (SSRs) are single-locus markers with high allelic variation and are widely applicable to different genotypes. We have now mapped 1810 SSR or sequence-tagged site markers in one or more of three recombinant inbred populations of soybean (the US cultivar 'Jack' x the Japanese cultivar 'Fukuyutaka', the Chinese cultivar 'Peking' x the Japanese cultivar 'Akita', and the Japanese cultivar 'Misuzudaizu' x the Chinese breeding line 'Moshidou Gong 503') and have aligned these markers with the 20 consensus linkage groups (LGs). The total length of the integrated linkage map was 2442.9 cM, and the average number of molecular markers was 90.5 (range of 70-114) for the 20 LGs. We examined allelic diversity for 1238 of the SSR markers among 23 soybean cultivars or lines and a wild accession. The number of alleles per locus ranged from 2 to 7, with an average of 2.8. Our high-density linkage map should facilitate ongoing and future genomic research such as analysis of quantitative trait loci and positional cloning in addition to marker-assisted selection in soybean breeding.

Abstract
BACKGROUND Red clover (Trifolium pratense L.) is a major forage legume that has a strong self-incompatibility system and exhibits high genetic diversity within populations. For several crop species, integrated consensus linkage maps that combine information from multiple mapping populations have been developed. For red clover, three genetic linkage maps have been published, but the information in these existing maps has not been integrated. RESULTS A consensus linkage map was constructed using six mapping populations originating from eight parental accessions. Three of the six mapping populations were established for this study. The integrated red clover map was composed of 1804 loci, including 1414 microsatellite loci, 181 amplified fragment length polymorphism (AFLP) loci and 204 restriction fragment length polymorphism (RFLP) loci, in seven linkage groups. The average distance between loci and the total length of the consensus map were 0.46 cM and 836.6 cM, respectively. The locus order on the consensus map correlated highly with that of accession-specific maps. Segregation distortion was observed across linkage groups. We investigated genome-wide allele frequency in 1144 red clover individuals using 462 microsatellite loci randomly chosen from the consensus map. The average number of alleles and polymorphism information content (PIC) were 9.17 and 0.69, respectively. CONCLUSION A consensus genetic linkage map for red clover was constructed for the first time based on six mapping populations. The locus order on the consensus map was highly conserved among linkage maps and was sufficiently reliable for use as a reference for genetic analysis of random red clover germplasms.

Abstract
DNA markers able to distinguish species or genera with high specificity are valuable in the identification of introgressed regions in interspecific or intergeneric hybrids. Intergeneric hybridization between the genera of Lolium and Festuca, leading to the reciprocal introgression of chromosomal segments, can produce novel forage grasses with unique combinations of characteristics. To characterize Lolium/Festuca introgressions, novel PCR-based expression sequence tag (EST) markers were developed. These markers were designed around intronic regions which show higher polymorphism than exonic regions. Intronic regions of the grass genes were predicted from the sequenced rice genome. Two hundred and nine primer sets were designed from Lolium/Festuca ESTs that showed high similarity to unique rice genes dispersed uniformly throughout the rice genome. We selected 61 of these primer sets as insertion-deletion (indel)-type markers and 82 primer sets as cleaved amplified polymorphic sequence (CAPS) markers to distinguish between Lolium perenne and Festuca pratensis. Specificity of these markers to each species was evaluated by the genotyping of four cultivars and accessions (32 individuals) of L. perenne and F. pratensis, respectively. Evaluation using specificity indices proposed in this study suggested that many indel-type markers had high species specificity to L. perenne and F. pratensis, including 15 markers completely specific to both species. Forty-nine of the CAPS markers completely distinguish between the two species at bulk level. Chromosome mapping of these markers using a Lolium/Festuca substitution line revealed syntenic relationships between Lolium/Festuca and rice largely consistent with previous reports. This intron-based marker system that shows a high level of polymorphisms between species in combination with high species specificity will consequently be a valuable tool in Festulolium breeding.

Abstract
* Fructan is the major nonstructural carbohydrate reserve in temperate grasses. To understand regulatory mechanisms in fructan synthesis and adaptation to cold environments, the isolation, functional characterization and genetic mapping of fructosyltransferase (FT) genes in perennial ryegrass (Lolium perenne) are described. * Six cDNAs (prft1-prft6) encoding FTs were isolated from cold-treated ryegrass plants, and three were positioned on a perennial ryegrass linkage map. Recombinant proteins were produced in Pichia pastoris and enzymatic activity was characterized. Changes in carbohydrate levels and mRNA levels of FT genes during cold treatment were also analysed. * One gene encodes sucrose-sucrose 1-fructosyltransferase (1-SST), and two gene encode fructan-fructan 6G-fructosyltransferase (6G-FFT). Protein sequences for the other genes (prfts 1, 2 and 6) were similar to sucrose-fructan 6-fructosyltransferase (6-SFT). The 1-SST and prft1 genes were colocalized with an invertase gene on the ryegrass linkage map. The mRNA levels of prft1 and prft2 increased gradually during cold treatment, while those of the 1-SST and 6G-FFT genes first increased, but then decreased before increasing again during a longer period of cold treatment. * Thus at least two different patterns of gene expression have developed during the evolution of functionally diverse FT genes, which are associated in a coordinated way with fructan synthesis in a cold environment.

Abstract
We generated a high-density genetic linkage map of soybean using expressed sequence tag (EST)-derived microsatellite markers. A total of 6920 primer pairs (10.9%) were designed to amplify simple sequence repeats (SSRs) from 63,676 publicly available non-redundant soybean ESTs. The polymorphism of two parent plants, the Japanese cultivar 'Misuzudaizu' and the Chinese line 'Moshidou Gong 503', were examined using 10% polyacrylamide gel electrophoresis. Primer pairs showing polymorphism were then used for genotyping 94 recombinant inbred lines (RILs) derived from a cross between the parents. In addition to previously reported markers, 680 EST-derived microsatellite markers were selected and subjected to linkage analysis. As a result, 935 marker loci were mapped successfully onto 20 linkage groups, which totaled 2700.3 cM in length; 693 loci were detected using the 668 EST-derived microsatellite markers developed in this study, the other 242 loci were detected with 105 RFLP markers, 136 genome-derived microsatellite markers, and one phenotypic marker. We examined allelic variation among 23 soybean cultivars/lines and a wild soybean line using 668 mapped EST-derived microsatellite markers (corresponding to 686 marker loci), in order to determine the transferability of the markers among soybean germplasms. A limited degree of macrosynteny was observed at the segmental level between the genomes of soybean and the model legume Lotus japonicus, which suggests that considerable genome shuffling occurred after separation of the species and during establishment of the paleopolyploid soybean genome.

Abstract
A perennial ryegrass cDNA clone encoding a putative glycine-rich RNA binding protein (LpGRP1) was isolated from a cDNA library constructed from crown tissues of cold-treated plants. The deduced polypeptide sequence consists of 107 amino acids with a single N-terminal RNA recognition motif (RRM) and a single C-terminal glycine-rich domain. The sequence showed extensive homology to glycine-rich RNA binding proteins previously identified in other plant species. LpGRP1-specific genomic DNA sequence was isolated by an inverse PCR amplification. A single intron which shows conserved locations in plant genes was detected between the sequence motifs encoding RNP-1 and RNP-2 consensus protein domains. A significant increase in the mRNA level of LpGRP1 was detected in root, crown and leaf tissues during the treatment of plants at 4 degrees C, through which freezing tolerance is attained. The increase in the mRNA level was prominent at least 2 h after the commencement of the cold treatment, and persisted for at least 1 week. Changes in mRNA level induced by cold treatment were more obvious than those due to treatments with abscisic acid (ABA) and drought. The LpGRP1 protein was found to localise in the nucleus in onion epidermal cells, suggesting that it may be involved in pre-mRNA processing. The LpGRP1 gene locus was mapped to linkage group 2. Possible roles for the LpGRP1 protein in adaptation to cold environments are discussed.

Abstract
The alpha-subunit of the casein protein kinase CK2 has been implicated in both light-regulated and circadian rhythm-controlled plant gene expression, including control of the flowering time. Two putative CK2alpha genes of perennial ryegrass (Lolium perenne L.) have been obtained from a cDNA library constructed with mRNA isolated from cold-acclimated crown tissue. The genomic organisation of the two genes was determined by Southern hybridisation analysis. Primer designs to the Lpck2a-1 and Lpck2a-2 cDNA sequences permitted the amplification of genomic products containing large intron sequences. Amplicon sequence analysis detected single nucleotide polymorphisms (SNPs) within the p150/112 reference mapping population. Validated SNPs, within diagnostic restriction enzyme sites, were used to design cleaved amplified polymorphic sequence (CAPS) assays. The Lpck2a-1 CAPS marker was assigned to perennial ryegrass linkage group (LG) 4 and the Lpck2a-2 CAPS marker was assigned to LG2. The location of the Lpck2a-1 gene locus supports the previous conclusion of conserved synteny between perennial ryegrass LG4, the Triticeae homoeologous group 5L chromosomes and the corresponding segment of rice chromosome 3. Allelic variation at the Lpck2a-1 and Lpck2a-2 gene loci was correlated with phenotypic variation for heading date and winter survival, respectively.

Abstract
We have developed a new procedure for Agrobacterium-mediated transformation of plants in the genus Beta using shoot-base as the material for Agrobacterium infection. The frequency of regeneration from shoot bases was analyzed in seven accessions of sugarbeet ( Beta vulgaris) and two accessions of B. maritima to select materials suitable for obtaining transformed plants. The frequency of transformation of the chosen accessions using Agrobacterium strain LBA4404 and selection on 150-mg/l kanamycin was found to be higher than that in previously published methods. Genomic DNA analysis and beta-glucuronidase reporter assays showed that the transgene was inherited and expressed in subsequent generations. In our method, shoot bases are prepared by a simple procedure, and transformation does not involve the callus phase, thus minimizing the occurrence of somaclonal variations.

Abstract
A 59-year-old woman who complained of anterior chest pain exhibited an abnormal shadow on chest X ray and was admitted to our hospital. The chest X ray showed a demarcated tumor at the anterosuperior mediastinum and she was diagnosed as having a mediastinal tumor. After the midsternotomy was performed, the mediastinal tumor derived from the thymic tissues was discovered to have invaded the right upper lung, pericardium and superior vena cava. After excising the tumor, anastomosis between the right brachiocephalic vein and superior vena cava, followed by that between the left brachiocephalic vein and right cardiac auricle was performed using expanded polytetrafluoroethylene-ringed vascular grafts (phi 10 mm) for reconstruction. The tumor was diagnosed as a thymic carcinoma (squamous cell carcinoma) pathologically. After surgery, she was treated by cobalt irradiation. One month and again 3 months after the operation, venography showed patency. The patient has not demonstrated recurrence for 9 years and 6 months.

Abstract
Advanced gastric, colon and esophageal cancers (n = 21) were treated with 5-FU (250 mg) modulated by CDDP (5 mg). The reductive ratio of tumor was 6/21 (28.6%). Six cases of partial response (PR) were limited with no surgical treatment and exploratory laparotomy of all cases, and the effectiveness rate was 54.5% (6/11). Few side effects, such as dysfunction of bone marrow and kidney, were noted. Even if side effects occurred, they were mild. We concluded that excellent treatment with 5-FU modulated by CDDP has markedly improved the efficacy.

Abstract
A 46-year-old female was admitted to our hospital on December 1991 for further examination of an abnormal shadow on chest X-ray. A huge mass in the upper mediastinum and a thin-walled cavitary lesion in the right upper lobe were found by chest radiography and computed tomography. On March 2, 1992, surgical resection was performed with pathological diagnosis of thymoma for the mediastinal mass and pulmonary cryptococcosis for the cavitary lesion. Although ATL cells were not found in the peripheral blood, anti-HTLV-1 antibody was found to be positive. Natural killer cell activity was lower than normal control and other tests of humoral and cell-mediated immunity were normal. Histological examination of the specimens obtained from the thymoma revealed lymphocytic predominance without atypical cells such as ATL cells, but with integration of HTLV-1 proviral DNA. There seemed to be a causal relationship between HTLV-1 carrier state and thymoma. Since there are no reported cases of HTLV-1 carrier associated with pulmonary cryptococcosis and thymoma, we report the first case with a review of the literature.

Abstract
The left lungs of 14 mongrel dogs were isolated, preserved, and then reperfused for 120 min. Three groups of lungs were investigated: group 1, nonpreserved lungs (control n = 5); group 2, lungs were flushed with UW solution and cold-stored (4-6 degrees C) in the same flush solution for 24 hr (n = 4); and group 3, lungs flushed and cold-stored with modified Euro-Collins' solution for 24 hr (n = 5). Airway pressure (AWP), static lung compliance (Cst), and pulmonary vascular resistance (PVR) 120 min after reperfusion were significantly higher in group 3 compared with the lungs in group 1 and group 2. AWP was 18.7 +/- 3.9 in group 1, 21.1 +/- 3.8 in group 2, and 33.8 +/- 9.2 ml/cmH2O (mean +/- SD) in group 3 (P less than 0.05). Cst was 14.0 +/- 3.5, 10.8 +/- 1.5, and 6.2 +/- 1.2 ml/cmH2O, respectively (P less than 0.01). Pulmonary vascular resistance was 125 +/- 16, 120 +/- 42, and 410 +/- 108 mmHg/L/min (P less than 0.05). We conclude that UW solution is useful for hypothermic canine lung preservation.

Abstract
Sensitivities to anti-tumor drugs, mitomycin C (MMC), aclarubicin hydrochloride (ACR), doxorubicin hydrochloride (ADR), cisplatin, and 5-fluorouracil (5FU), were examined using PK-1, -8, -9, -12, -14, and -16 cell lines derived from human pancreatic cancer. These cell lines showed different sensitivities to each of the above anti-tumor drugs. The concentrations required for 50% growth-inhibition (IC50) after 2 hours of exposure were 0.096 to 0.35 micrograms/ml for MMC, 0.0074 to 0.0076 micrograms/ml for ACR, 0.033 to 0.23 micrograms/ml for ADR, 0.35 to 1.9 micrograms/ml for cisplatin, and 21 to 42 micrograms/ml for 5FU, IC50 of each anti-tumor drug decreased significantly after 48 hours of exposure. The combination of any two out of MMC, ACR, and 5FU showed synergistic inhibition of the growth of PK-1 and PK-8 cell lines. These results show that MMC, ACR, ADR, cisplatin, and 5FU have sufficient anti-tumor effect against six human pancreatic cancer cell lines even at clinically achievable concentrations and exposure times, and chemotherapy for pancreatic cancers requires naturally effective drug delivery into cancer tissues.

Abstract
Six human pancreatic cancer cell lines PK-1, -8, -9, -12, -14 and -16, were established. They originated from either primary pancreatic cancer biopsy or liver metastasis biopsy, or xenografts of these biopsy specimens in athymic nude mice. The primary tumors were all well differentiated adenocarcinomas of pancreatic duct origin. The six established PK cell lines were all CEA positive and had tumorigenicity in athymic nude mice. Morphology of the xenografted tumors was closely similar to that of the original tumor. PK cells grew slowly with the doubling time of 41.3 to 82 hr and showed aneuploid chromosome pattern. High levels of glucose-6-phosphate dehydrogenase (G6PDH) and lactic dehydrogenase (LDH) were found in each cell extract. Trypsin was not detected in cell extracts except PK-8 and PK-9. In chemosensitivity test, all of PK cell lines were sensitive to aclacinomycin A (ACM), and PK-1 and PK-8 were sensitive to 5-Fluorouracil (5-Fu) at concentrations of 0.02 microgram/ml, ACM and 1 microgram/ml, 5-Fu, when the drugs were used for over 48 hr. At higher concentrations, they showed time independent sensitivity to mitomycin C (MMC). PK-9 was resistant to 5-Fu and MMC.

Abstract
We measured plasma levels of vitamin E (total tocopherol) and lipoperoxide in seventeen neonates (less than 10 days), twenty infants (1-12 months) and ten children (1-5 years) during anaesthesia. The seventeen neonates were randomly divided into two groups; seven who received 30 mg X kg-1 of alpha-tocopheryl acetate intramuscularly before anaesthesia and ten who did not. The 20 infants were divided into three groups: Group 1: eight infants who did not receive vitamin E; Group 2: six who received 30 mg X kg-1 of alpha-tocopheryl acetate orally for three days before anaesthesia; Group 3: six who received 30 mg X kg-1 of alpha-tocopheryl acetate intramuscularly three hours before anaesthesia. In the neonates who did not receive alpha-tocopheryl acetate, plasma vitamin E and lipoperoxide levels were unchanged following surgery. In Group 1 infants, plasma vitamin E levels decreased (p less than 0.05) and plasma lipoperoxide levels increased (p less than 0.05). In both neonates who received vitamin E and Group 3 infants the mean plasma vitamin E levels increased significantly (p less than 0.05) following surgery. In Group 2 infants, the levels of plasma vitamin E before surgery were high, as compared to the other groups: however, plasma vitamin E levels decreased following surgery. In the children, the plasma vitamin E levels were unchanged, while the plasma lipoperoxide levels decreased significantly (p less than 0.05) during anaesthesia. It is suggested from our studies that plasma vitamin E levels decrease and plasma lipoperoxide levels increase during anaesthesia and surgery in infants; however, those levels are unchanged in neonates.

Abstract
In order to elucidate the immunological defense mechanism in tumor bearing hosts against pancreatic cancer, tissue reactions of the regional lymph nodes were investigated in terms of extension and prognosis of pancreatic cancer. As the site for investigation of lymph nodes, the paracortical area, germinal center and sinus histiocyte systems were selected. In each case paracortical hyperplasia, germinal center hyperplasia and sinus histiocytosis were graded and the relationship between grade and prognosis of resected pancreatic cancer was studied with the following results. The grades of each tissue reaction in cases without lymph node metastasis were higher than that observed in cases with metastasis. There was a significant difference in sinus histiocytosis (p less than 0.01). Higher grade tissue reactions were observed in cases with primary lesion histologic type classified as papillary adenocarcinoma or as well-differentiated tubular adenocarcinoma as compared to those in cases of poorly differentiated histologic type. In pancreatic cancer the prognosis was better in cases with higher grade of tissue reactions of the regional lymph nodes. In cases with pancreatic cancer both cellular immunity and humoral immunity are involved in the host defense mechanism. It was considered that sinus histiocytosis is significant as an indicator for good prognosis and a factor to inhibit progression in pancreatic cancer.
