Vinje MA, Gartman LS, Simmons CH. Characterization of a near isogenic barley line with high grain β-amylase activity reveals a separation in the tight co-regulation of B-hordeins (Hor2) with endosperm-specific β-amylase (Bmy1). Gene 2024:148799. [PMID: 39067543 DOI: 10.1016/j.gene.2024.148799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 07/01/2024] [Accepted: 07/24/2024] [Indexed: 07/30/2024]
Abstract
GSHO 2096 is a near isogenic barley line with extremely high grain β-amylase activity, a desirable trait in the malting and brewing industry. High levels of grain β-amylase activity are caused by a surge in endosperm-specific β-amylase (Bmy1) gene expression during the early stages of grain development with high expression levels persisting throughout development. Origins of the high β-amylase activity trait are perplexing considering GSHO 2096 is not supposed to have grain β-amylase activity. GSHO 2096 is reported to be derived from a Bowman x Risø 1508 cross followed by recurrent backcrossing to Bowman (BC5). Risø 1508 carries a mutated form of the barley prolamin binding factor, which is responsible for Bmy1 expression during grain development. Thus, the pedigree of GSHO 2096 was explored to determine the potential origins of the high grain β-amylase trait. Genotyping using the barley 50 k iSelect SNP array revealed Bowman and GSHO 2096 were very similar (95.4 %) and provided evidence that both Risø 56 and 1508 are in the pedigree. Risø mutants 56 and 1508 both have perturbed hordein gene expression leading to a discernable pattern using SDS-PAGE. GSHO 2096 and Risø 56 have the same hordein pattern whereas Bowman and Risø 1508 have unique patterns. RNAseq revealed that Hor2 (B-hordein) gene expression was completely downregulated making it unique as the only known line with Bmy1 expression without Hor2 co-expression. Regardless of pedigree, GSHO 2096 remains an extremely valuable high β-amylase activity line with potential utilization in breeding for malt quality.

Vinje MA, Simmons CH. Characterization of barley (Horduem vulgare) lys3 mutants identifies genes under the regulation of the prolamin-box binding transcription factor and elucidates its role in endosperm promoter methylation during grain development. Mol Genet Genomics 2024; 299:17. [PMID: 38416243 DOI: 10.1007/s00438-024-02112-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 12/24/2023] [Indexed: 02/29/2024]
Abstract
Barley ranks fourth in global cereal production and is primarily grown for animal feed and malt. Hordeins, the principal barley seed storage proteins, are homologous to wheat gluten and when ingested elicit an immune response in people with Coeliac disease. Risø 1508 is a chemically induced barley mutant with low hordein levels imparted by the lys3.a locus that is reported to be caused by an SNP in the barley prolamin-box binding factor gene (BPBF). Reports suggest the lys3.a locus prevents CG DNA demethylation at the Hor2 (B-hordein) promoter during grain development subsequently causing hypermethylation and inhibiting gene expression. In lys3.a mutants, endosperm-specific β-amylase (Bmy1) and Hor2 are similarly downregulated during grain development and thus we hypothesize that the inability to demethylate the Bmy1 promoter CG islands is also causing Bmy1 downregulation. We use whole-genome bisulfite sequencing and mRNA-seq on developing endosperms from two lys3.a mutants and a lys3.b mutant to determine all downstream genes affected by lys3 mutations. RNAseq analysis identified 306 differentially expressed genes (DEGs) shared between all mutants and their parents and 185 DEGs shared between both lys3.a mutants and their parents. Global DNA methylation levels and promoter CG DNA methylation levels were not significantly different between the mutants and their parents and thus refute the hypothesis that the lys3.a mutant's phenotype is caused by dysregulation of demethylation during grain development. The majority of DEGs were downregulated (e.g., B- and C-hordeins and Bmy1), but some DEGs were upregulated (e.g., β-glucosidase, D-hordein) suggesting compensatory effects and potentially explaining the low β-glucan phenotype observed in lys3.a germplasm. These findings have implications on human health and provide novel insight to barley breeders regarding the use of BPBF transcription factor mutants to create gluten-free barley varieties.

Abstract
Barley is a very important crop particularly in marginal dry areas, where it often serves as the most viable option for farmers. Additionally, barley carries great significance in the Western world, serving not only as a fundamental crop for animal feed and malting but also as a nutritious food source. The broad adaptability of barley and its ability to withstand various biotic and abiotic stresses often make this species the sole cereal that can be cultivated in arid regions. The collection and utilization of barley genetic resources are crucial for identifying valuable traits to enhance productivity and mitigate the adverse effects of climate change. This review aims to provide an overview of the management and exploitation of barley genetic resources. Furthermore, the review explores the relationship between gene banks and participatory breeding, offering insights into the diversity and utilization of barley genetic resources through some examples such as the initiatives undertaken by ICARDA. Finally, this contribution highlights the importance of these resources for boosting barley productivity, addressing climate change impacts, and meeting the growing food demands in a rapidly changing agriculture. The understanding and utilizing the rich genetic diversity of barley can contribute to sustainable agriculture and ensure the success of this vital crop for future generations globally.

Abstract
This study aimed at investigating the effects of genotype and temperatures on the proteolytic activity in green malt of 48 barley genotypes, including 19 mutants, 15 hulled, 4 hulless, and 10 wild using enzyme assays based on casein, as substrate. During malting, insoluble barley protein must be hydrolyzed into soluble peptides and free amino acids to supply the brewing yeast with sufficient nutrients to grow rapidly and metabolize glucose and other sugars into alcohol through fermentation. However, the relatively hot temperatures employed during kilning usually denature the proteolytic enzymes due to their thermolabile nature. Even though the hydrolytic activity of most of the proteases is destroyed during the kilning process, the malt includes a small fraction of thermostable proteases that can further degrade protein in the subsequent mashing process. Considering the higher temperature range employed in industrial kilning and mashing, three temperatures (37, 50, and 70°C) were selected to identify the genotypes possessing high activity at the higher range of temperatures as well as thermostable variant of the enzyme. The proteolytic activity in all the genotypes declined after 50°C depicting its optimum temperature. Overall proteolytic activity was observed to be positively correlated with the amino acids and negatively correlated with protein content. Three mutant (BL2086, BL2091, and BL2079) and one wild (WS 237) genotypes possessing proteolytic activity in a higher range at all the studied temperatures have the potential to be exploited in the breeding programs for incorporating trait of thermostable proteolytic activity into low malting efficiency cultivars. PRACTICAL APPLICATION: The optimal hydrolytic activities of carbohydrases and proteases during mashing are essential for producing high-quality wort from malted barley to ensure that hydrolyzed molecules are available to brewers' yeast to support fermentative metabolism. In this study, several barley cultivars were grown under identical environmental conditions but assayed at different temperatures. As result, four genotypes had been obtained that possessed optimal proteolytic activities at a higher temperature range and can be of great interest to breeders and maltsters for altering wort amino acid profiles and better exposure of starch to mashing enzymes, thereby increasing the fermentable sugar yield from the malt.

Abstract
Abstract
Barley is the fourth largest cereal crop in the world. It is mainly used for feeding, beer production and food. Barley is receiving more attention from both agricultural and food scientists because of its special chemical composition and health benefits. In comparison with other cereal crops, including wheat, rice and maize, barley grains are rich in dietary fiber (such as β-glucan) and tocols, which are beneficial to human health. It is well proved that diets rich in those chemicals can provide protection against hypertension, cardiovascular disease, and diabetes. Barley has been widely recognized to be great potential as a healthy or functional food. In this review, we present the information about the studies on physical structure of barley grain and the distribution of main chemical components, nutrient and functional composition of barley grain and their health benefits, and the approaches of improving and utilizing the nutrient and functional chemicals in barley grain. With the development of processing technologies, functional components in barley grains, especially β-glucan, can be efficiently extracted and concentrated. Moreover, nutrient and functional components in barley grains can be efficiently improved by precise breeding and agronomic approaches. The review highlights the great potential of barley used as healthy and functional foods, and may be instructive for better utilization of barley in food processing.

Abstract
Malting is the process of preparing barley for brewing through partial germination followed by drying. This process softens the grain cell wall and stimulates the production of diastatic enzymes, which convert starch into malt extract. The suitability of a barley grain for malt production depends upon a large number of quality parameters that are crucial for the identification and release of high-quality malt varieties. Maintaining tight control of these quality attributes is essential to ensure high processing efficiency and final product quality in brewery and malt house. Therefore, we have summarized the basic malting process and various physiological and biochemical quality parameters that are desirable for better malt quality. This study may provide an understanding of the process, problems faced, and opportunities to maltsters and researchers to improve the malt efficiency by altering the malting process or malt varieties.

Abstract
Barley is the most commonly used grain in the brewing industry for the production of beer-type beverages. This review will explore the extraction and application of proteins from barley, particularly those from brewers’ spent grain, as well as describing the variety of proteins present. As brewers’ spent grain is the most voluminous by-product of the brewing industry, the valorisation and utilisation of spent grain protein is of great interest in terms of sustainability, although at present, BSG is mainly sold cheaply for use in animal feed formulations. There is an ongoing global effort to minimise processing waste and increase up-cycling of processing side-streams. However, sustainability in the brewing industry is complex, with an innate need for a large volume of resources such as water and energy. In addition to this, large volumes of a by-product are produced at nearly every step of the process. The extraction and characterisation of proteins from BSG is of great interest due to the high protein quality and the potential for a wide variety of applications, including foods for human consumption such as bread, biscuits and snack-type products.

Abstract
Seeds have evolutionarily developed to store protein without immediately degrading it and constitute ideal tissues for recombinant protein storage. Unfortunately, the production of recombinant protein in seeds is compromised by low yield as compared to other heterologous expression systems. In order to improve the yield of the human epidermal growth factor (EGF) in barley, protein sink-source relations in the developing grain were modulated towards EGF instead of the barley storage protein. The EGF gene, under the control of a B-hordein and a seed-specific oat globulin promoter, was introduced by crossing EGF lines into the Risø 56 mutant deficient in B-hordein storage protein synthesis. Offspring plants were analysed for EGF and Hordein expression and for expression of the unfolded protein response (UPR) genes PDI and CRT to monitor changes in ER stress levels. EGF content was increased significantly in the mature grain of homozygous offspring and PDI and CRT gene expressions were upregulated. We demonstrate, for the first time in barley, that replacement of an abundant seed storage protein with a specific heterologous protein driven by the promoter of the removed gene can accelerate the production of a specific heterologous protein in barley grains.

Abstract
Barley grain protein content (GPC) is an important quality factor that determines grain end-use value. The synthesis and accumulation of grain protein is highly dependent on the availability of nitrogen fertilizer, and it is important to understand the underlying control mechanisms of this. In the current study, the GPC and protein composition of mature grain seeds from Yangsimai 3 and Naso Nijo barley cultivars were analyzed. Grain storage subproteomes (albumin, glubulin, hordein and glutelin) were compared in the cultivars grown in both low and high nitrogen level conditions. The GPC of mature grain was significantly higher in Yangsimai 3 than Naso Nijo following nitrogen treatment. Albumin, hordein and glutelin content were increased in Yangsimai, while only hordein content was increased in Naso Nijo. Large-scale analysis of the grain storage subproteome revealed 152 differentially expressed protein spots on 2-DE gels with a pH range of 3-10. Among these, 42 and 66 protein spots were successfully identified by tandem mass spectrometry in Yangsimai 3 and Naso Nijo grown in low and high nitrogen conditions. The identified proteins were further grouped into thirteen categories according to their biological functions. This detailed analysis of grain subproteomes provides information on how barley GPC may be controlled by nitrogen supply.

In barley (Hordeum vulgare L.), one gene (HvXYN-1) that encode a endo-beta-1,4-xylanase, has been cloned. However, the single nucleotide polymorphisms (SNPs) that affect the endoxylanase activity and total arabinoxylan (TAX) content have yet to be characterized. The investigation of genetic variation in HvXYN1 may facilitate a better understanding of the relationship between TAX content and EA activity in barley. RESULTS In the current study, 56 polymorphisms were detected in HvXYN1 among 210 barley accessions collected from 34 countries, with 10 distinct haplotypes identified. The SNPs at positions 110, 305, 1045, 1417, 1504, 1597, 1880 bp in the genomic region of HvXYN1 were significantly associated with EA activity (P < 0.0001), and the sites 110, 305, and 1045 were highly significantly associated with TAX content. The amount of phenotypic variation in a given trait explained by each associated polymorphism ranged from 6.96 to 9.85%. Most notably, we found two variants at positions 1504 bp and 1880 bp in the second exon that significantly (P < 0.0001) affected EA activity; this result could be used in breeding programs to improve beer quality. In addition, African accessions had the highest EA activity and TAX content, and the richest germplasm resources were from Asia, indicating the high potential value of Asian barley. CONCLUSION This study provided insight into understanding the relationship, EA activity, TAX content with the SNPs of HvXYN1 in barley. These SNPs can be applied as DNA markers in breeding programs to improve the quality of barley for beer brewing after further validation.

Abstract
The impact of malting on composition and malt quality parameters such as diastatic power, α-amylase activity, β-amylase activity, hot water extract and β-glucan content were investigated in five different Indian barley cultivars. Protein content of grains increased significantly after malting. Soluble protein content of unmalted grain, which ranged from 3.20-3.93% increased after malting to 4.26-4.85%. Diastatic power of mature grain varied across genotype and their level increased (58.98-81.05 to 115.93-142.45 DP°) after malting. Diastatic power correlated very strongly with protein content (r = 0.90) and strongly with β-amylase activity (r = 0.74). α-amylase, which was low (0.042-0.189 Ceralpha Unit/g) initially in unmalted grain, was synthesized during germination to the range of 149.42-223.78 Ceralpha Unit/g. The correlation between diastatic power and α-amylase was very weak (r = - 0.04). The levels of β-amylase in unmalted grain was in the range of 13.97-18.26; that amount got reduced after malting to 12.55-15.97 Betamyl-3 U/g. β-amylase had a strong positive correlation (r = 0.85) with grain protein. Malted grain which had higher protein content showed very strong negative correlation (r = - 0.86) with hot water extract value. β-glucan content reduced 70-80% from the initial level, across genotypes.

Abstract
β-Amylase from un-germinated seeds of peanut (Arachis hypogaea) was purified to apparent electrophoretic homogeneity with final purification fold of 205 and specific activity of 361μmol/min/mg protein. The enzyme was purified employing simple purification techniques for biochemical characterization. The purified enzyme was identified as β-amylase with Mr of 31kDa. The enzyme displayed its optimum catalytic activity at pH5.0 and 60°C with activation energy of 4.5kcal/mol and Q10 1.2. The enzyme displayed Km and Vmax values, for soluble potato starch of 1.28mg/mL and 363.63μmol/min/mg, respectively. Thermal inactivation of β-amylase at 65°C resulted into first-order kinetics with rate constant 0.0126min-1 and t½ 55min. The enzyme was observed to act on native granular potato starch, which could minimize the high cost occurring from solubilization of starch in industries. Enzyme fractions scavenge 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical, indicating its antioxidative nature. In addition, the purified β-amylase was successfully utilized for the improvement of antioxidant potential of wheat. These findings suggest that β-amylase from peanuts have potential application in food and pharmaceutical industries.

Abstract
Grain weight and protein content will be reduced and increased, respectively, when barley is subjected to water stress after anthesis, consequently deteriorating the malt quality. However, such adverse impact of water stress differs greatly among barley genotypes. In this study, two Tibetan wild barley accessions and two cultivated varieties differing in water stress tolerance were used to investigate the genotypic difference in metabolic profiles during grain-filling stage under drought condition. Totally, 71 differently accumulated metabolites were identified, including organic acids, amino acids/amines, and sugars/sugar alcohols. Their relative contents were significantly affected by water stress for all genotypes and differed distinctly between the wild and cultivated barleys. The principal component analysis of metabolites indicated that the Tibetan wild barley XZ147 possessed a unique response to water stress. When subjected to water stress, the wild barley XZ147 showed the most increase of β-amylase activity among the four genotypes, as a result of its higher lysine content, less indole-3-acetic acid (IAA) biosynthesis, more stable H2O2 homeostasis, and more up-regulation of BMY1 gene. On the other hand, XZ147 had the most reduction of β-glucan content under water stress than the other genotypes, which could be explained by the faster grain filling process and the less expression of β-glucan synthase gene GSL7. All these results indicated a great potential for XZ147 in barley breeding for improving water stress tolerance.

Abstract
Grain protein contents (GPCs) of barley seeds are significantly different between feed and malting barley cultivars. However, there is still no insight into the proteomic analysis of seed proteins between feed and malting barley cultivars. Also, the genetic control of barley GPC is still unclear. GPCs were measured between mature grains of Yangsimai 3 and Naso Nijo. A proteome profiling of differentially expressed protein was established by using a combination of 2-DE and tandem mass spectrometry. In total, 502 reproducible protein spots in barley seed proteome were detected with a pH range of 4-7 and 6-11, among these 41 protein spots (8.17%) were detected differentially expressed between Yangsimai 3 and Naso Nijo. Thirty-four protein spots corresponding to 23 different proteins were identified, which were grouped into eight categories, including stress, protein degradation and post-translational modification, development, cell, signaling, glycolysis, starch metabolism, and other functions. Among the identified proteins, enolase (spot 274) and small subunit of ADP-glucose pyrophosphorylase (spot 271) are exclusively expressed in barley Yangsimai 3, which may be involved in regulating seed protein expression. In addition, malting quality is characterized by an accumulation of serpin protein, Alpha-amylase/trypsin inhibitor CMb and Alpha-amylase inhibitor BDAI-1. Most noticeably, globulin, an important storage protein in barley seed, undergoes post-translational processing in both cultivars, and also displays different expression patterns.

Abstract
Fenugreek (Trigonella foenum-graecum) seeds do not contain starch as carbohydrate reserve. Synthesis of starch is initiated after germination. A β-amylase from ungerminated fenugreek seeds was purified to apparent electrophoretic homogeneity. The enzyme was purified 210 fold with specific activity of 732.59 units/mg. Mr of the denatured enzyme as determined from SDS-PAGE was 58 kD while that of native enzyme calculated from size exclusion chromatography was 56 kD. Furthermore, its identity was confirmed to be β-amylase from MALDI-TOF analysis. The optimum pH and temperature was found to be 5.0 and 50°C, respectively. Starch was hydrolyzed at highest rate and enzyme showed a Km of 1.58 mg/mL with it. Antibodies against purified Fenugreek β-amylase were generated in rabbits. These antibodies were used for localization of enzyme in the cotyledon during different stages of germination using fluorescence and confocal microscopy. Fenugreek β-amylase was found to be the major starch degrading enzyme depending on the high amount of enzyme present as compared to α-amylase and also its localization at the periphery of amyloplasts. A new finding in terms of its association with protophloem was observed. Thus, this enzyme appears to be important for germination of seeds.

Abstract
The objective of this study was to determine if developing barley (Hordeum vulgare L.) seeds had differences in β-amylase 1 (Bmy1) mRNA accumulation, β-amylase (EC 3.2.1.2) activity, β-amylase protein accumulation, and total protein levels during late seed development from genotypes with different Bmy1 intron III alleles. Two North American malting barley cultivars (Hordeum vulgare ssp. vulgare) were chosen to represent the Bmy1.a and Bmy1.b alleles and, due to limited Bmy1 intron III allele variation in North American cultivars, two wild barleys (Hordeum vulgare ssp. spontaneum) were chosen to represent the Bmy1.c and Bmy1.d alleles. Wild barleys Ashqelon (Bmy1.c) and PI 296897 (Bmy1.d) had 2.5- to 3-fold higher Bmy1 mRNA levels than cultivars Legacy (Bmy1.a) and Harrington (Bmy1.b). Levels of Bmy1 mRNA were not significantly different between cultivated or between wild genotypes. In all four genotypes Bmy1 mRNA levels increased from 17 to 19 days after anthesis (DAA) and remained constant from 19 to 21 DAA. Ashqelon and PI 296897 had more β-amylase activity on a fresh weight basis than Legacy and Harrington at all developmental stages. β-Amylase protein levels increased from 17 DAA to maturity in all genotypes. Total protein in grains from wild genotypes was significantly higher than cultivated genotypes at all developmental stages. Higher levels of total protein in Ashqelon and PI 296897 could explain their higher levels of β-amylase activity, when expressed on a fresh weight basis. When β-amylase activities are expressed on a protein basis there are no statistical differences between the wild and cultivated barleys at maturity.

Abstract
BACKGROUND Structurally different areas may occur in the endosperm of the barley grain, and they can be visually classified as either mealy or steely. Barleys with a high proportion of grains that are mostly steely often show uneven physical-chemical modification of the endosperm during malting. To study the relationship between steeliness and endosperm modification, two samples of barley cv. Scarlett with contrasting malting quality were analysed. RESULTS The proportions of steely grains were 77% and 46% in the two samples, which were then defined as steely sample and mealy sample, respectively. The steely sample showed slower modification during malting (in terms of beta-glucan degradation, friability increase, and Calcofluor staining), lower hot water extract (HWE) and acrospire growth, and higher extract viscosity. Endosperm permeation to large molecules (tested with the fluorescein isothiocyanate-dextran conjugate, FITC-D) closely followed cell wall modification in the steely sample, but this was not so in the mealy sample. CONCLUSIONS Higher steeliness was associated with higher levels of C hordeins in the grain of barley cv. Scarlett. It is proposed that such hordeins can increase the permeability to large molecules (FITC-D) but slow modification. Like steeliness and the level of C hordeins, permeability to FITC-D appears to be more linked to environmental rather than genetic effects. Although a more general association of C hordeins with steeliness of malting barley still has to be ascertained, the negative role of C hordeins in malting quality has been confirmed.

Abstract
A procedure for identification of malting barley varieties using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) of ethanol-soluble barley proteins (hordeins) is described. The hordeins were first extracted from milled barley grains by several extraction protocols (using different extraction agents and conditions). Hordein extracts were then analyzed directly via MALDI-TOF MS without any preliminary purification or separation step, and the protein profiles of analyzed hordein extracts were compared in order to find out the most suitable extraction procedure for mass spectrometric analysis. The optimized procedure was successfully applied to identification of 13 malting barley varieties. Our results revealed that the proposed mass spectrometry-based approach provides characteristic mass patterns of extracted hordeins, which can be advantageously used for barley variety identification.

Abstract
A large fraction of protein N harvested with crop seeds is derived from N remobilisation from senescing vegetative plant parts, while a smaller fraction stems from de novo N assimilation occurring after anthesis. This study contrasts near-isogenic barley (Hordeum vulgare L.) germplasm, varying in the allelic state of a major grain protein content (GPC) locus on chromosome 6. Plant material was grown under both low- and high-N fertilisation levels. The analyses indicated that leaf N remobilisation occurred earlier in high-GPC germplasm under both fertilisation regimes, as indicated by an earlier decrease of total leaf N, chlorophylls, soluble- and membrane-proteins. At the same time, kernel free amino acid levels were enhanced, while leaf free amino acid levels were lower in high-GPC barleys, suggesting enhanced retranslocation of organic N to the developing sinks. Enhanced or longer availability of leaf nitrates was detected in high-GPC varieties and lines, at least under high N fertilisation, indicating that the GPC locus profoundly influences whole-plant N allocation and management. Results presented here, together with data from a recent transcriptomic analysis, make a substantial contribution to our understanding of whole-plant N storage, remobilisation and retranslocation to developing sinks.

Abstract
OBJECTIVES We have investigated the extent of contamination with wheat, barley, rye or a mixture of these cereals in a large number of grains and commercial oats. We have also attempted to identify the type of cereal contaminant. METHODS Sandwich R5 ELISA (using either gliadins or hordeins as standards), western blot, matrix-assisted laser desorption/ionization time-of-flight mass spectrometric and quantitative real-time PCR (Q-PCR) techniques have been used to analyze a total of 134 oats, comprising grains and commercial oat products collected from Europe, the United States and Canada. RESULTS Twenty-five of the 134 pure, uncontaminated oat varieties were found to have undetectable levels of gluten, whereas most of the 109 grains and commercial oat products were mainly contaminated with mixtures of wheat, barley and rye, barley being the predominant contaminant. The percentages of these cereals in the oat samples have been calculated by specific wheat, barley and rye Q-PCR systems. The oat samples were grouped according to the avenin spectra determined by the mass spectrometric technique. The data confirmed that contaminated oat foods, based on the same variety, could have different levels of wheat, barley and rye contamination. CONCLUSION This study has verified that contamination with wheat gliadins or barley hordeins in oat samples can be measured by the Sandwich R5 ELISA, using either gliadins or hordeins as standards, and also the importance of using confirmatory techniques (such as western blot, Q-PCR and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry) to confirm that most oats are contaminated with mixtures of wheat, barley and rye.

Abstract
To identify genes involved in the regulation and execution of leaf senescence and whole-plant nitrogen reallocation, near-isogenic barley germplasm divergent in senescence timing and protein concentration of mature grains was contrasted. Barley lines differing in allelic state at a major locus on chromosome six, controlling grain protein concentration, were obtained after four generations of backcrossing. Based on physiological data indicating major differences between low- and high-grain protein germplasm at 14-21 d past anthesis, the flag leaf and kernel transcriptomes of the low-protein parent and one high-protein near-isogenic line were compared at these time points, using the 22-k Barley1 Affymetrix microarray. Our data associate several genes with both known (based on sequence comparisons) and unknown functions with the senescence process. These include leucine-rich repeat transmembrane protein kinases, a glycine-rich RNA-binding protein with homology to AtGRP7 and a 'mother of FT/TF1' gene. Our data also indicate upregulation of genes coding for both plastidial and extraplastidial proteases in germplasm with accelerated leaf senescence. Functional characterization of candidate genes identified by this research may contribute to our understanding of the molecular network underlying leaf senescence and nitrogen reallocation.
