Abstract
A bread wheat line (N11) and a disomic 2D(2R) substitution triticale line were crossed and backrossed four times. At each step electrophoretic selection for the seeds that possessed, simultaneously, the complete set of high molecular weight glutenin subunits of N11 and the two high molecular weight secalins of rye, present in the 2D(2R) line, was carried out. Molecular cytogenetic analyses of the BC4F8 generation revealed that the selection carried out produced a disomic addition line (2n = 44). The pair of additional chromosomes consisted of the long arm of chromosome 1R (1RL) from rye fused with the satellite body of the wheat chromosome 6B. Rheological analyses revealed that the dough obtained by the new addition line had higher quality characteristics when compared with the two parents. The role of the two additional high molecular weight secalins, present in the disomic addition line, in influencing improved dough characteristics is discussed.

Abstract
The unique 75 K γ-secalins encoded by Sec2 loci in Secale species is composed of almost half rye storage proteins. The chromosomal location of Sec2 loci in wild Secale species, Secale africanum, was carried out by the wheat—S. africanum derivatives, which were identified by genomic in situ hybridization and multi-color fluorescence in situ hybridization. The Sec2 gene-specific PCR analysis indicated that the S. cereale Sec2 was located onchromosome 2R, while the S. africanum Sec2 was localized on chromosome 6Rafr of S. africanum. A total of 38 Sec2 gene sequences were isolated from S. africanum, S. cereale and S. sylvestre by PCR-based cloning. Phylogenetic analysis showed that S. africanum Sec2 diverged from S. cereale Sec2 approximately 2–3 million years ago. The illegitimate recombination of chromosome 2R–6R involving the Sec2 loci region may accelerate sequence variation during evolutionary process from wild to cultivated Secale species.

Molecular, physicochemical and rheological characteristics of introgressive Triticale/Triticum monococcum ssp. monococcum lines with wheat 1D/1A chromosome substitution. Int J Mol Sci 2013; 14:15595-614.

Abstract
Three sets of hexaploid introgressive triticale lines, with Triticum monococcum ssp. monococcum (cultivated einkorn wheat) genes and a bread wheat chromosome 1D substituted for chromosome 1A, and one set of secondary triticale lines were evaluated for grain and flour physicochemical and dough rheological characteristics in two generations (F7 and F8). Genomic in situ hybridization (GISH) and fluorescence in situ hybridization (FISH) confirmed the 1D/1A chromosome substitution. The presence or absence of einkorn high-molecular-weight (HMW) glutenin subunits and the wheat Glu-D1d locus encoding the 5 + 10 subunits was assessed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), capillary zone electrophoresis, and allele-specific molecular markers. Significant differences were found among physicochemical properties (with the exception of the Hagberg falling number) of all introgressive Triticale/T. monococcum lines and the secondary triticale lines. The wheat 1D/1A chromosome substitution also affected these properties. The results showed that in all introgressive triticale lines, the protein and gluten content, Zeleny sedimentation value, and water absorption capacity, were increased. The rheological parameters estimated using micro-farinograph, reomixer, and Kieffer dough extensibility systems also showed an appreciable increase in dough-mixing properties, maximum resistance to extension (Rmax), and dough extensibility. Introgressive Triticale/T. monococcum lines with 5 + 10 subunits have particularly favorable rheological parameters. The results obtained in this study suggest that the cultivated einkorn genome Am, in the context of hexaploid secondary triticale lines and with a wheat 1D/1A substitution, has the potential to improve gluten polymer interactions and be a valuable genetic resource for triticale quality improvement.

Abstract
Currently, due to the abandonment of traditional agricultural practices and the decline of rye production in Portugal, there is a need to assess the genetic diversity of rye in order to preserve its biodiversity. Furthermore, a greater knowledge of rye secalins is important for rye bread-making quality and other crop breeding purposes. The genetic variation and diversity of storage proteins were estimated for fourteen populations of rye (Secale cereale L.) sampled in northern Portugal. The work showed the high genetic diversity within the Portuguese rye gene-pool as an important source for plant breeding and emphasized the necessity of an integrated resources genetic program to allow a more efficient management and conservation of these resources. The rye populations were compared with 'Picasso' and 'Marder' varieties. Several alleles were identified by the single electrophoretic mobility patterns. We studied a set of 1600 rye seeds, including regional populations and varieties, having observed a total of 24, 5, 21 and 47 alleles for HMW, 75k γ-, 40k γ- and ω-secalins, respectively. The coefficient of similarity within populations is presented using cluster representation. The mean value of genetic variation indices (H) for rye storage proteins was very high in regional populations, ranging from 0.67 to 0.78, while in the varieties ranged from 0.57 to 0.58. Knowledge of the diversity of secalins will increase our understanding of the quality differences between rye varieties, especially considering the relative small number of rye cultivars grown around the world.

Abstract
Capillary zone electrophoretic (CZE) analysis of monomeric prolamins (wheat gliadins and rye secalins) covered 28 hexaploid triticale ( Triticosecale x Wittm.) cultivars. The ethanol-soluble proteins were separated on an uncoated fused-silica capillary using the isoelectric 60 mM iminodiacetic (IDA) buffer in conjunction with 20% (v/v) acetonitrile and 0.075% (w/v) polyvinylpyrrolidone (PVP). For each separation, dynamic coating of the capillary wall with a buffer containing 0.1 M IDA and 0.05% (w/v) hydroxypropylmethylcellulose (HPMC) was performed. Separations of prolamins provided very good resolution and high reproducibility (<0.8% RSD). Prolamin profiles of all analyzed cultivars showed both qualitative and quantitative differences, including number of peaks, presence or absence of peaks, and area of peaks. The number of prolamin peaks detected in particular triticale cultivars varied from 22 to 28; in total, 56 components were distinguished. The CZE electropherograms of prolamins showed five main groups of protein peaks, in order of mobility alpha-prolamins, beta-prolamins, gamma-prolamins, omega1-prolamins, and omega2-prolamins, with migration times of 6.8-7.7, 7.8-10.4, 10.5-12.2, 12.3-17.4, and 17.5-25.6 min, respectively. Triticale seeds in comparison with wheat contained fewer alpha-prolamins and higher quantity of omega-prolamins. Hierarchical clustering of the investigated cultivars was based on Bhattacharyya distances calculated from the CZE data. The cultivars grouped in four main clusters. The obtained CZE results were compared with A-PAGE data.

Abstract
An improved method for separating and characterizing high molecular weight glutenin subunits (HMW-GS) in hexaploid triticale by capillary zone electrophoresis (CZE) was developed. A low-concentrate mixture of hydrophilic polymers, poly(vinylpyrrolidone) (PVP) and hydroxypropylmethylcellulose (HPMC), in an isoelectric buffer was employed for dynamic coating of the capillary inner wall. In separation buffer PVP with lower concentrated poly(ethylene oxide) (PEO) was replaced. The CZE electropherograms of HMW-GS showed two group peaks in accordance with x- and y-type subunits with migration times of 6.8-7.8 and 8.4-11.5 min, respectively. In total, 14 HMW subunits (2 subunits encoded by Glu-A1 locus and 12 by Glu-B1) were identified. The CZE analyses revealed that each of the subunits Bx7 and By8 determined by SDS-PAGE makes up three subunits (Bx6.8, Bx7, and Bx7* and By8, By8*, and new By8**, respectively), with different migration times. It was also shown that the subunits By18 and By20 in triticale determined by SDS-PAGE have different migration times in comparison with the same subunits in bread wheat. For these new HMW-GS, the following names were assigned: By18* instead of By18 and By20* instead of By20. The presented CZE method is an efficient alternative to the SDS-PAGE procedure for early selection of useful triticale genotypes with good breadmaking quality.

Abstract
High yield potential and the wide adaptability of wheat-rye T1BL·1RS translocation lines are attractive to breeders. The wheat-rye lines Lankao 1, 3, 4, and 5 were resistant to a wide spectrum of wheat powdery mildew (Blumeria graminis f. sp. tritici) isolates from both China and Canada. They also were resistant to a mixture of wheat stem rust (Puccinia graminis f. sp. tritici) pathotypes (98WSR) and wheat stripe rust (P. striiformis f. sp. tritici) races from western Canada and China. Colonization of wheat curl mite (WCM) (Aceria tosichella) resulted in slower development of rolling and trapping leaves in the Lankao lines than in the WCM-susceptible check cultivars. The delayed development of Wheat streak mosaic (WSM) symptoms on Lankao lines was observed when transmitted by viruliferous WCM, even though they were susceptible to Wheat streak mosaic virus (WSMV). This effect of Lankao lines on limiting the spread of WSM was comparable with other known sources of WCM resistance. Sequential C-banding and genomic in situ hybridization analyses revealed the presence of a pair of T1BL·1RS translocated chromosomes in the Lankao lines. Segregation analysis of the F2 progeny plants derived from crosses between Lankao 4 and the susceptible wheat cvs. Mingxian 169 and Lovrin 13 indicated that a single dominant gene was responsible for the isolate-specific resistance against wheat powdery mildew in Lankao 4. Polymerase chain reaction analysis using an STS marker amplified rye chromatin in powdery mildew-resistant and -susceptible F2 plants of the Mingxian 169 × Lankao 4 cross demonstrated that the resistance of Lankao 4 was not controlled by a gene or genes located on the rye chromosome arm of T1BL·1RS. The resistance of the Lankao lines to diseases and limitation of the spread of WSMV, in combination with good quality and high yield potential, makes them useful for wheat improvement and production.

Abstract
Wheat 1BL/1RS translocations are widely planted in China as well as in most of the wheat producing area in the world for their good qualities of disease resistance and high yield. 1BL/1RS translocations are however poor in bread making, partially caused by a family of small monomeric proteins, omega-secalins, which are encoded by genes on 1RS. Based on published sequence of a rye omega-secalin gene we designed a pair of primers to cover the whole mature protein coding sequence. A major band could be amplified from 1BL/1RS translocations but not from euploid wheat. Using this primer set we conducted PCR amplification by using high fidelity Pfu polymerase on the genomic DNAs and cDNAs purified from a 1BL/1RS translocation Lankao 906. Sequencing analysis indicated that this gene family contains several members of 1150 bp, 1076 bp, 1075 bp, 1052 bp and 1004 bp genes, including two pseudogenes and three active genes. The gene transcripts were differentially expressed in developing seeds.

Abstract
A gametocidal chromosome derived from Aegilops triuncialis (3C) induces chromosome mutations in gametes lacking the 3C chromosome in common wheat (Triticum aestivum L.). We combined 3C with chromosome 1R of rye (Secale cereale L.) in a common wheat line to know how efficiently 3C induces transfers of small 1R segments to wheat. In the 811 progeny of this wheat line, we found five wheat chromosomes (2A, 2D, 3D, 5D and 7D) carrying segments of the 1R satellite. Wheat plants carrying these translocations were tested for the presence of a storage protein locus Sec-1 and a cluster of resistance genes for wheat rust diseases, Sr31, Lr26 and Yr9. The 2A and 2D translocations had the Sec-1 and three rust resistance loci. The 3D and 5D translocations had Sr31, Lr26 and Yr9 but not Sec-1. The 7D translocation lacked Sec-1, Lr26 and Yr9, but the presence of Sr31 in this translocation was not determined. This showed that the translocation points fell into three regions of the 1R satellite, namely, proximal to Sec-1, between Sec-1 and the rust resistance loci, and distal to the rust resistance loci. Thus, the 3C gametocidal system was demonstrated to be effective in transferring small rye chromosome segments.

Abstract
The structural genes for the omega-secalins of rye (Secale cereale) are located in the Sec-1 locus on the short arm of rye chromosome 1R. We applied PCR (polymerase chain reaction) to detect the Sec-1 locus in a wheat genomic background. A primer set we designed based on a published sequence of a omega-secalin gene amplified not only the omega-secalin sequence, but also a putative omega-gliadin sequence. We determined partial sequences of both PCR-amplified fragments and designed different primers for the specific amplification of the omega-secalin sequence. One of the new primer sets amplified DNA fragments only in rye and wheat lines carrying chromosome 1R or telosome 1RS; no amplification occurred in either euploid wheats or 1RS deletion lines. This PCR-based method would provide efficient screening for the Sec-1 locus in progeny of wheat lines carrying chromosome 1R.

Abstract
A simple monoclonal antibody-based screening test has been developed for the presence of translocations of the short arm of chromosome 2 of rye (2RS) with wheat chromosome 2B. 2RS encodes a set of about three polypeptides known as Mr 75 000 gamma-secalins. Use of the antibody test for these secalins enabled screening of several hundred seeds per day. The antibody could readily distinguish 2BL–2RS translocations and 2R substitutions from 1BL–1RS translocations or nontranslocation wheats. Use of the antibody in analysis of segregating progeny for Sec-2 in several wheat backgrounds was successful. Results with a selection of the seed population were checked using protein gel electrophoresis, with 100% correct confirmation. Key words : rye, wheat, seed proteins, translocation, diagnostic test.

Abstract
The Sec-1 locus (ω-secalin) of rye (Secale cereale L.) was mapped in the satellite of the short arm of chromosome 1R using fluorescence in situ hybridization and a genomic probe called pSec2B. Sec-1 is located in the middle of the satellite at the junction of the proximal euchromatic and the distal heterochromatic regions. Double hybridization experiments using rDNA and pSec2B showed that the NOR spans over the secondary constriction of the short arm of chromosome 1R and that there is a clearly visible gap between the NOR and Sec-1. Heterologous hybridization of pSec2B to barley visualized the B-hordein locus on chromosome 1H.Key words: fluorescence in situ hybridization, physical mapping, genetic mapping, secalin, rye, B-hordein, rDNA.

Abstract
A correspondence between RFLP patterns and gliadin alleles at the Gli-1 and Gli-2 loci was established in a set of 70 common wheat (T.aestivum L.) cultivars using γ-gliadin (K32) and α-gliadin (pTU1) specific probes. All Gli-B1 and Gli-D1 alleles which differed in encoded γ-gliadins showed definite RFLP patterns after hybridization with the K32 probe. Two groups of Gli-B1 alleles, Gli-B1b-like and Gli-B1e-like, were identified, and these could originate from distinct genotypes of the presumptive donor of the B-genome. Intralocus recombination and/or gene conversion as well as small deletions, gene silencing and gene amplification were assumed to be responsible for the origin of new gliadin alleles. Silent γ-gliadin sequences were shown to exist in all of the genotypes studied. K32 also differentiated Gli-A1a from all other Gli-A1 alleles as well as the Gli-B11 allele in cultivars carrying the 1B/1R (wheat/rye) translocation. PTU1 was shown to recognize several Gli-A2 alleles, but not the Gli-B2 or Gli-D2 alleles. Moreover, this probe hybridized to chromosome 1R sequences suggesting the existence of rye gene(s), probably silent, for α-gliadin-like proteins on chromosome 1R.

Abstract
In order to reach a higher accuracy concerning the cytological locations of the rye seed storage protein lociSec2[Gli-R2] andSec3[Glu-R1] located within chromosome arms 2RS and 1RL, respectively, the linkage relationships between the following loci were analyzed: isozyme lociGpi-R1,Mdh-R1, andPgd2, translocationT273W (Wageningen tester set, involving chromosome arms 1RS and 5RL), the telomere C-bands of chromosome arms 1RL (tL1), 2RS (tS2), and 5RS (tS5), and three interstitial C-bands in chromosome arm 1RS (iS1), in the middle of chromosome arm 1RL (iL1), and in the middle of chromosome arm 2RL (iL2), respectively. The data indicated that locusSec3 is located in the distal half of chromosome arm 1RL (between C-bandiL1 and locusPgd2), while locusSec2 is located a short distance (2.9 ± 1.4%) from the telomere C-band of chromosome arm 2RS.

Abstract
Rye secalins, telomeric C-bands, and telocentric chromosomes were used as markers in the progeny of a test-cross in order to determine the position of seed storage-protein genes Glu-R1 and Gli-R1 with respect to the centromere and both telomeres of chromosome 1 R in rye. These genes were linked to the centromere (32.35±3.28% and 36.27±3.37% recombination, respectively). Glu-R1 was loosely linked to the telomere of the long arm (43.63±3.47% recombination), while Gli-R1 was closely linked to the telomere of the short arm (9.80±2.08% recombination). This finding supports the possibility that rye ω- and γ-secalin genes may be located on the satellites, as has been described in wheat for genes that code similar proteins. The importance of metaphase-I pairing failure and its consequences for the estimation of the recombination fraction are also discussed.

Abstract
Analyses of wheat/rye addition lines by Southern blotting confirmed the presence of sequences related to the Sec 1, Sec 2, and Sec 3 loci on chromosomes 1R and 2R. Comparison of the 1R and 2R addition lines allowed the identification of gamma-secalin genes at Sec 1 and Sec 2, respectively, while omega-secalin and gamma-secalin genes at Sec 1 were discriminated by comparative hybridization with three probes: omega-secalin, total gamma-secalin, and 3' gamma-secalin. The high molecular weight (HMW) secalin genes at Sec 3 were identified using a homologous HMW subunit probe from wheat. Gene copy numbers were estimated as about 40-60 for omega-scalins, 5-10 for gamma-secalins, and 2 for HMW secalins. Comparison of individual plants of cv. Gazelle showed a high degree of polymorphism, particularly for sequences related to omega-secalins and HMW secalins.

Abstract
The progenies of two different rye test-crosses were analyzed for secalin proteins by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) using unreduced and reduced aqueous ethanol extracts. Segregation for two high-molecular-weight secalin bands (Glu-R1 or Sec3), one ω-secalin band (Gli-R1 or Sec-1), two 40K γ-secalin bands (Gli-R1 or Sec1) and two ω-type secalin bands (new locus) were studied. One recombinant between ω- and γ-secalins was found in one test-cross. The new locus, designated Gli-R3 or Sec-4, was mapped between Glu-R1 and Gli-R1, more displaced towards Gli-R1. In test-cross 1 recombination between Glu-R1 and Gli-R3 was 33.80±3.22%, and between Gli-R3 and Gli-R1, 12.04±2.21%. In the other test-cross the map distances were relatively similar but smaller, likely due to less recombination within two different species of Secale. Genes coding for 40K γ-secalins at Gli-R1 were likely proximal to the centromere with respect to genes coding for ω-secalins at the same complex locus.

Abstract
Chromosome 1R of rye (Secale cereale) is one of the most intensively used sources of alien chromatin in bread wheat. It provides a source of valuable disease resistance genes and its widespread use has stimulated the development of genetic maps incorporating protein and DNA markers. Published data as well as new mapping data were combined into a consensus map by using common markers in the different mapping studies to orient the various data sets relative to each other. The consensus map provides a tentative order, and relative distances, between the genetic markers. A summary of the dispersed repetitive sequences that are now available for the detection and characterization of chromosome 1R segments in wheat is also provided.

Abstract
Anther culture, when applied to hexaploid triticale×wheat hybrids, offers the opportunity to re-assort wheat D genome and rye R genome chromosomes into homozygous doubled haploid lines in a single generation. The characterisation of such lines is the first step in their utilisation in wheat improvement. Two lines, M24 and M25 from the cross of 'Beagle'×'Kedong 58', and one line, M27, from the cross 'Beagle'×'Jinghua No. 1' have been characterised using different methods including conventional cytology and chromosome banding, and by using marker systems for storage protein composition (glutenins and gliadins), isozymes (α-amylase, aminopeptidase, glutamate oxaloacetic transaminase (GOT)) and RFLP markers. The results from all approaches were consistent in proving that M24 is a whole chromosome 6R/6D substitution line, while M25 and M27 are whole chromosome 1R/1D substitution lines. The relative advantages and disadvantages of each method of identification are also discussed.

Abstract
The endosperm proteins encoded by the genome Hch in Hordeum chilense, Tritordeum (amphiploid Hordeum chilense x Triticum turgidum), common wheat-H. chilense addition lines, and the segregating plants resulting from the cross Tritordeum x T. turgidum, were fractionated by three electrophoretical techniques: SDS-PAGE, A-PAGE, and bidimensional PAGE. Prolamin subunits with a high molecular weight (HMW) were well visualized by SDS-PAGE, the A-PAGE technique permitted good resolution for many hordeins and gliadins, and two-dimensional electrophoresis allowed new sets of bands coded by gene complexes from H. chilense chromosomes to be distinguished. The loci Hor-Hch1 (up to 11 subunits belonging to the ω-, β - and α-hordeins), Glu-Hch1 (one HMW prolamin subunit), Hor-Hch2 (one α-hordein), and Hor-Hch3 (up to four α-hordeins) were located on the H. chilense chromosomes 1Hch, 5Hch, and 7Hch.

Abstract
The genes controlling resistance to three wheat rusts, viz., leaf rust (Lr26), stem rust (Sr31) and stripe or yellow rust (Yr9), and ω-secalins (Sec1), located on the short arm of rye chromosome 1R, were mapped with respect to each other and the centromere. Analysis of 214 seeds (or families derived from them) from testcrosses between a 1BL.1RS/1R heterozygote and 'Chinese Spring' ditelocentric 1BL showed no recombination between the genes for resistance to the three rusts, suggesting very tight linkage or perhaps a single complex locus conferring resistance to the three rusts. The rust resistance genes were located 5.4 ± 1.7 cM from the Sec1 locus, which in turn was located 26.1 ± 4.3 cM from the centromere; the gene order being centromere - Sec1 - Lr26/Sr31/Yr9 - telomere. In a second test-cross, using a different 1BL.1RS translocation which had only stem rust resistance (SrR), the above gene order was confirmed despite a very large proportion of aneuploids (45.8%) among the progeny. Furthermore, a map distance of 16.0 ± 4.8 cM was estimated for SrR and the telomeric heterochromatin (C-band) on 1RS. These results suggest that a very small segment of 1RS chromatin is required to maintain resistance to all three wheat rusts. It should be possible but difficult to separate the rust resistance genes from the secalin gene(s), which are thought to contribute to dough stickiness of wheat-rye translocation lines carrying 1RS.

Abstract
An F1 plant fromSecale cereale ssp.ancestrale xtelocentric substitution lines3R of the cultivated rye "Petkus spring" was used as female in a cross with the inbred line Riodeva (I28), which has the standard chromosome arrangement. Single plants from this backcross progeny were analyzed for chromosome constitution, storage protein, and isozymic patterns. The seed protein loci were identified asSec-1a andSec-1b loci controlling 40-Kγ-secalins andω-secalins, respectively. These loci are located on the short arm of chromosome1R. TheSec-3 locus controlling high-molecular-weight secalins is located on the long arm of chromosome1R. A further seed protein locus,Pr-3 (55-K protein), was located on the short arm of chromosome1R. A linkage was found between the6Pgd-2 isozyme locus controlling 6-phosphogluconate dehydrogenase isozymes located on the long arm of chromosome1R and the four seed protein loci. The results favor the gene order:6Pgd-2 ...Sec-3 ... [centromere] ...Pr-3 ...Sec-1b ...Sec-1a. Other linkages detected werePer-3a andPer-3b (0.33±0.33 cM),Est-8 andEst-12 (0.33±0.33 cM), andGot-3 and centromere (20.57±2.42 cM). The proxidase (Per), glutamate oxaloacetate transaminase (Got), and esterase (Est) loci were located on chromosome arms2RS,3RL, and6RL, respectively. The distances and the maps obtained are compared with data available in the literature.

Abstract
Fifty-two progenies originating from a cross between 8x and 4x triticale were submitted to cytogenetic analyses and to various electrophoretic studies [high-molecular-weight (HMW) glutelins, HMW secalins, γ-secalins, α and ω-gliadins, β-amylases] to identify new genetic structures, more specifically the input of the D genome in a genetic context other than the wheat one. Markers of the rye genome (HMW and ω-secalins) were identified in all of the triticale lines, but they originated either from the 4x or from the 8x parent, or from both. Chromosomes 4A, 1B, and 2R, present in both parents, showed the same banding patterns in all progenies. Chromosomes 1R and 5R, present in both parents, showed heterogeneous labelling. The expression of chromosomes 6A, 1D, and 4D, present in the 8x parent only, was more complex with a possible involvement of a regulatory system. Several hexaploid progenies had introgressed part of the D genome, suggesting that crossing 8x and 4x triticale was a practicable approach for transferring D chromosomes into hexaploid triticale.

Progenies of a tetraploid 1BL/1RS wheat-rye translocation line, CV 256, selected from the cross 'Cando' x 'Veery', were analyzed by means of Giemsa C-banding. CV 256 is cytologically stable for the presence of the 1BL/1RS translocation but still segregating for A- and B-genome chromosomes of 'Cando' and 'Veery'. In CV 256, nucleolar activity of the 1RS NOR locus is suppressed, as judged by the absence of a secondary constriction in that rye segment and the capability of organizing nucleoli. PAGE analysis of prolamins confirmed the presence of two 1RS secalins in all single seeds analyzed. SDS-PAGE analysis of reduced glutenins of single seeds indicated that some seeds contained the 'Cando' Glu-B1 locus (subunits 6+8), some contained the 'Veery' Glu-B1 locus (subunits 7+9) while others contained all four subunits, indicating that the material was heterozygous. Pm8 resistance is expressed in the tetraploid 1BL/1RS translocation line based on the reactions of six well-defined powdery mildew isolates. However, Pm8 resistance is not expressed in the hexaploid wheat cultivars 'Olymp', 'Heinrich' and 'Florida', which also contain the 1BL/1RS translocation. Obviously, the existence of the 1BL/1RS translocation is not a proof for the expression of the associated genes. PAGE results did not show a clear linkage between powdery mildew resistance and the presence of 1RS secalins.

Abstract
Haynaldia villosa is a wild grass of the tribe Triticeae, other members of which include the cultivated cereals barley, rye, and wheat. We have made an electrophoretic and chemical characterization of the major seed storage proteins (prolamins) of H. villosa and determined the chromosomal locations of the structural genes for some components using the available wheat/H. villosa chromosome addition lines. As in wheat, barley, and rye, groups of high molecular weight (polymeric), sulfur-poor (monomeric), and sulfur-rich (monomeric gamma-type and polymeric) prolamins can be recognized. Most of the components are encoded by genes on chromosome 1 Ha, which is homologous with the chromosomes controlling many of the prolamins in wheat and rye and all of those in barley. In addition, H. villosa also contains alpha-type sulfur-rich prolamins, previously detected only in wheat and its close relatives. These may be encoded by genes on chromosome 6Ha, which is homologous with the group 6 chromosomes that control the alpha-type gliadins of wheat. Despite the proposed close relationship between Haynaldia and ryes, no evidence was found for the presence of proteins closely related to the Mr 75,000 gamma-secalins which are characteristic of wild and cultivated species of Secale.

Abstract
The proteins of Hordeum chilense grain were resolved into 25 major components by two-dimensional electrophoresis. Their solubilities in aqueous alcohol solutions were determined to distinguish prolamin storage proteins from metabolic and structural proteins. The prolamins were divided into two groups, based on the presence or absence of intermolecular disulfide bonds determined by gel-filtration chromatography. Using an incomplete set of Chinese Spring wheat-H. chilense disomic addition lines, the structural genes of 21 of the 26 most dominant seed proteins were assigned to chromosomes. The great majority of the prolamin genes, including those coding for a high molecular weight (HMW) prolamin subunit, was present on chromosome 1 Hch. However, a small number of prolamin genes also occurred on chromosomes 5 Hch and 7 Hch. A minor protein, probably belonging to the nonstorage group of proteins, is coded by genes on 5 Hch. Various ditelosomic addition lines and ditelosomic and disomic substitution lines for chromosome 7 Hch were also analyzed by electrophoresis. This technique revealed that the genes for three major prolamins occur on the beta arm of chromosome 7 Hch and that a gene for a minor protein, also thought to be a prolamin, occurs on the alpha arm. These results are discussed in relation to the evolution of prolamin genes in the Triticeae.

Abstract
Sixteen allosyndetic recombinants involving chromosome arms 1DS and 1RS derived from the wheat-rye translocation 1DL-1RS, and one 1RS recombinant derived from 1BL-1RS were characterised by cytological, biochemical and molecular methods. Analysis of isozyme markers showed that recombination had involved different breakpoints along the 1DS arm. The gene order Tri-D1 - Per-D1 - Gpi-D1 - Gli-D1 was established on chromosome 1DS, and this is consistent with the gene order known to occur on 1BS. The use of three molecular probes for loci on 1RS confirmed one of the recombinants obtained from the 1BL-1RS translocation, and two of the three recombinants obtained from the 1DL-1RS translocation. These two recombinant chromosomes appear to have approximately reciprocal structures and may prove of direct benefit to wheat breeders as they retain the stem rust resistance of the parental translocation but have recovered some of the 1D encoded proteins which are absent in 1DL-1RS lines and which are thought to affect dough quality. A 5S RNA site was discovered on chromosome arm 1DS, probably reflecting the homoeologous relationship of this chromosome with 1BS. Segregational analysis indicated that some of the homoeologous wheat-wheat exchanges probably involved more than a single allosyndetic event.

Abstract
Chromosome pairing between rye chromosome arm 1RS, present in two wheat-rye translocation stocks, and its wheat homoeologues was induced by introducing the translocations into either a ph1bph1b or a nullisomic 5B background. This rye arm carries a gene conferring resistance to wheat stem rust, but lines carrying the translocation produce a poor quality dough unsuitable for breadmaking. Storage protein markers were utilised along with stem rust reaction to screen for allosyndetic recombinants. From a 1DL-1RS translocation, three lines involving wheat-rye recombination were recovered, along with thirteen lines derived from wheat-wheat homoeologous recombination. From a 1BL-1RS translocation, an additional three allosyndetic recombinants were recovered. Nullisomy for chromosome 5B was as efficacious as the ph1b mutant for induction of allosyndesis, and the former stock is easier to manipulate due to the presence of a 5BL-encoded endosperm protein. The novel wheat-rye chromosomes present in the recombinant lines may enable the rye disease resistance to be exploited without the associated dough quality defect.

Abstract
Progress in rye karyology is reviewed with respect to chromosome structure, recognition and chromosome nomenclature. Considerable contributions have been brought about by molecular techniques which have even revealed nucleotide sequences of some of the ribosomal DNA. DNA sequence organization correlates with the distribution of major Giemsa C-band regions as well as with N-bands and the binding sites of fluorescent dyes. The several banding patterns permit the classification of rye chromosomes. The increased data and widespread application of banding analysis require a consistent system of chromosome and/or band designation. Therefore, a standard band nomenclature is proposed with reference to the recommendations of the "Paris Conference on Standardization in Human Cytogenetics". In addition, advances in genetics are summarized and discussed. Based on the original accepted standard karyogram and banding patterns of the rye chromosomes, meanwhile, 120 genes determining several characters have been associated with individual chromosomes and/or chromosome arms, including linkage studies for about 19 arrangements. Most results were obtained using wheat-rye addition lines as well as test crosses with defined translocations. Moreover, genetical studies based on appropriate trisomic and telotrisomic material resulted in the localization of 19 genes, including their linkage relationships.
