“…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).…”

“…We used 12 wild (H. spontaneum) (Table S1) and 9 cultivated barley plants (Table S2) to conduct an RNA-seq analysis. Six wild-barley accessions from the Near East were collected and previously characterized by Nevo et al (26)(27)(28). Six wild-barley genotypes were from the collection of Xu, since the 1960s, from the extensive area of the Tibetan Plateau (11,12), and evaluated by Dai et al (14,47) and Qiu et al (48).…”

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

“…This value indicates that about 53 allelic substitutions per 100 gene loci have occurred in their separate evolution. Nevo et al (1979Nevo et al ( , 1981 have surveyed the genetic diversity and environmental associations in wild barley and wheat. The range of genetic distances between populations in these autogamous species was less than we observed in A. canariensis.…”

We have shown at the Tabigha microsite that soil type (basalt vs. terra-rossa) is an important *Correspondence.…”

Edaphic natural selection of allozyme polymorphisms in Aegilops peregrina at a Galilee microsite in Israel

Allozymic diversity in proteins encoded by 19 loci was analysed electrophoretically in 70 individual plants of the wild tetraploid wheat Aegilops peregrina, from a microsite at Tabigha, north of the Sea of Galilee, Israel. The test involved a 100 m transect, equally subdivided into basalt and terra-rossa soil types and comparisons were based on the two polymorphic esterase loci. Significant genetic differentiation according to soil type was found over very short distances. Our results suggest that allozyme polymorphisms in A. peregrina are adaptive and that they differentiate primarily by soil selection, probably through aridity stress.
