“…Although some studies have identified barley landraces with unique genome structures, it is not being researched extensively. For example, European barley is grouped into three subpopulations based on the sequence of the photoperiod response gene ( Ppd-H1 ) [ 18 – 20 ]. Six different haplotypes were found in Asian barley populations, identified by the β-amylase gene ( Bmy1 ) at positions 115, 165, 233, 347, and 430, which allows adaptation and selection based on the preference for climate, and food [ 21 – 23 ].…”

Barley is the fifth most important food crop in Ethiopia. The genetic relationship and population structure studies of barley are limited to gene bank collections. Therefore, this study fills a gap by investigating the selection, consumption, economic value, genetic diversity, and population structure of farm-collected barley from the Gumer district of the Gurage Zone, which has received little attention. The information on the use of barley in the study area was collected using semi-structured interviews and questionnaires. 124 households of 11 kebeles, the smallest community unit, were interviewed. Barley landraces collected were compared with those collected from Japan, the United States (USA), and other Ethiopian locations. Illumina iSelect (50K genotyping platform) was used to identify single nucleotide polymorphisms (SNP) (20,367). Thirty landraces were found in Gumer. Burdaenadenber had the highest on-farm Shannon index estimate (2.0), followed by Aselecha (1.97) and Enjefo (1.95). Aselecha and Fetazer had the highest (44%) and the lowest (29%) richness values, respectively. High and low Simpson index values were found in Aselecha (84%) and Wulbaragenateretero (79%), respectively. The neighbor-joining tree revealed that Gumer landraces formed a separate subcluster with a common ancestral node; a sister subcluster contained barley landraces from Japan. According to the population structure analysis, barley landraces from Gumer differed from Japan and the United States. The principal component analysis revealed that US barley was the most distant group from Gumer barley. The markers’ allele frequencies ranged from 0.10 to 0.50, with an average value of 0.28. The mean values of Nei’s gene diversity (0.38) and the polymorphic information content (0.30) indicated the presence of high genetic diversity in the samples. The clustering of accessions was not based on geographic origin. Significant genetic diversity calls for additional research and analysis of local barley diversity because the selection and use of barley in Ethiopia would have been affected by the preference of ethnic groups.

“…It has been shown that Ppd-H1 is the ortholog of the wheat Ppd-D1 gene, a member of the pseudoresponse regulator ( PRR ) gene family via homology-based cloning (Beales et al, 2007 ). The major determinants of the long-day response in barley are the Photoperiod-H1 ( Ppd-H1 ) and Photoperiod-H2 ( Ppd-H2 ) genes on chromosomes 2H and 1H, respectively (Abdullaev et al, 2017 ). The results of the study of Turner et al ( 2005 ) suggest that Ppd-H1 might affect flowering by altering the expression of photoperiod pathway genes that are under circadian control.…”

Barley ( Hordeum vulgare L.) is one of the most important cereal crops worldwide. In the Qinghai-Tibet Plateau, six-rowed hulless (or naked) barley, called “qingke” in Chinese or “nas” in Tibetan, is produced mainly in Tibet. The complexity of the environment in the Qinghai-Tibet Plateau has provided unique opportunities for research on the breeding and adaptability of qingke barley. However, the genetic architecture of many important agronomic traits for qingke barley remains elusive. Heading date (HD), plant height (PH), and spike length (SL) are three prominent agronomic traits in barley. Here, we used genome-wide association (GWAS) mapping and GWAS with eigenvector decomposition (EigenGWAS) to detect quantitative trait loci (QTL) and selective signatures for HD, PH, and SL in a collection of 308 qingke barley accessions. The accessions were genotyped using a newly-developed, proprietary genotyping-by-sequencing (tGBS) technology, that yielded 14,970 high quality single nucleotide polymorphisms (SNPs). We found that the number of SNPs was higher in the varieties than in the landraces, which suggested that Tibetan varieties and varieties in the Tibetan area may have originated from different landraces in different areas. We have identified 62 QTLs associated with three important traits, and the observed phenotypic variation is well-explained by the identified QTLs. We mapped 114 known genes that include, but are not limited to, vernalization, and photoperiod genes. We found that 83.87% of the identified QTLs are located in the non-coding regulatory regions of annotated barley genes. Forty-eight of the QTLs are first reported here, 28 QTLs have pleotropic effects, and three QTL are located in the regions of the well-characterized genes HvVRN1, HvVRN3 , and PpD-H2 . EigenGWAS analysis revealed that multiple heading-date-related loci bear signatures of selection. Our results confirm that the barley panel used in this study is highly diverse, and showed a great promise for identifying the genetic basis of adaptive traits. This study should increase our understanding of complex traits in qingke barley, and should facilitate genome-assisted breeding for qingke barley improvement.

“…Each subunit is formed by acidic (α) and basic (β) polypeptides bound by disulfide bonds. Up to six types of subunits and polypeptides were identified that differ in charge and molecular weight (Anisimova and Gavrilyuk, 1989). The subunits are classified into three types, A, B and C, depending on their molecular weight.…”

Some results of the studies of plant genetic resources held in the VIR Department of Genetics are discussed in light of N. I. Vavilov’s theories of natural plant immunity, homologous series in hereditary variability, and interspecific hybridization. The long-term investigations resulted in identifying bread wheat, cultivated barley, oat, rye and sorghum accessions with new effective genes for resistance to diseases and pests. The large-scale immunological screening has revealed a narrow genetic diversity in wheat and barley for resistance to biotic and abiotic stressors. On the example of sunflowers, the significance of seed storage proteins for solving problems of domestication and introgressive hybridizations is demonstrated.
