“…1 A and B). Based on the results of population structure, we divided all of the wild-barley accessions into three groups: Wb-T accessions from the Tibetan Plateau and its vicinity (11,12); Wb-NE1 accessions from Israel (26-28); and four Wb-NE2 accessions: B1K-04-12 (21) and ECI-2-0 (27) from Israel, Iran-6-26 from Gawdar, Iran (29), and Turkey-19-24 from Bitlis, Turkey (30) ( Table S1). The results suggested that the wild barley from the Near East have wide genetic diversity (21,(26)(27)(28)(29)(30), which could be divided into two or more subgroups, and are also consistent with the report that incipient sympatric speciation might begin to occur between the two opposite slopes of "Evolution Canyon" at Mount Carmel, Israel, despite their geographical proximity (31).…”

The domestication of cultivated barley has been used as a model system for studying the origins and early spread of agrarian culture. Our previous results indicated that the Tibetan Plateau and its vicinity is one of the centers of domestication of cultivated barley. Here we reveal multiple origins of domesticated barley using transcriptome profiling of cultivated and wild-barley genotypes. Approximately 48-Gb of clean transcript sequences in 12 Hordeum spontaneum and 9 Hordeum vulgare accessions were generated. We reported 12,530 de novo assembled transcripts in all of the 21 samples. Population structure analysis showed that Tibetan hulless barley (qingke) might have existed in the early stage of domestication. Based on the large number of unique genomic regions showing the similarity between cultivated and wildbarley groups, we propose that the genomic origin of modern cultivated barley is derived from wild-barley genotypes in the Fertile Crescent (mainly in chromosomes 1H, 2H, and 3H) and Tibet (mainly in chromosomes 4H, 5H, 6H, and 7H). This study indicates that the domestication of barley may have occurred over time in geographically distinct regions.evolution | genetic diversity | genomic similarity | RNA-Seq | single nucleotide variants

“…Correlation between ecological variability and genetic diversity in H. murinum (Ourari et al 2011) and in its allies such as H. vulgare subsp. spontaneum (see for example Nevo et al 1986;Graner et al 2003) are documented. Thus, it can be concluded that the genetic diversity within H. murinum may have an ecogeographical basis.…”

Genetic diversity and geographic distribution of variation of Hordeum murinum as revealed by retroelement insertional polymorphisms in Iran

Hordem murinum is a widespread weedy/wild species, growing in different ecological conditions in Iran. Populations of H. murinum subsp. glaucum (2n = 2x = 14) and subsp. leporinum (2n = 4x, 6x = 28, 42) are found in this region. Inter-retroelement amplified polymorphism (IRAP) markers were used to analyse the genetic diversity of 57 accessions of H. murinum from different regions of Iran, and to examine patterns of diversity related to the taxonomy and geography. Eight IRAP primer combinations amplified a total of 241 distinct DNA fragments sized 150-1400 bp, from which 236 (97.9%) were polymorphic. On average, each primer combination amplified about 30.12 fragments (ranged from 23 to 34) in PCR. The patterns of genetic diversity were closely correlated with taxonomic groups, ploidy levels and geographic origin. Along with the high genetic diversity, three geographic sub-genepools were evident, 1: in the North-Northeast region along the Alborz Mountains, 2: in the West-Northwest region along the Zagros Mountains, and 3: in the Central -Southern region. The genetic diversity in diploids was higher than polyploids. Also genetic diversity in W-NW region along the Zagros Mountains was considerably higher than that of the other regions.

“…This is another symptomatic event of clonal structure. To illustrate this, the values found in various animal species are as follows: cats in Spain, Balearic Islands and Italy (G ST = 0.03, 0.02 and 0.03, respectively, Ruiz-Garcia 1993, 1994a, Randi & Ragni 1991 Nevo et al 1986), and Triticum turgidum (G ST = 0.37, Nevo et al 1988). None of these values get near that obtained for Trypanosoma.…”
