Analysis of genetic diversity of hordein in wild close relatives of barley from Tibet.
We analyzed genetic diversity in the storage protein hordein encoded at Hor-1, Hor-2 and Hor-3 loci in seeds from 211 accessions of wild close relatives of barley, Hordeum vulgare ssp. agriocrithon and H. vulgare ssp. spontaneum. Altogether 32, 27 and 13 different phenotypes were found for Hor-1, Hor-2 and Hor-3, respectively. A comparison of our results with those of previous studies indicates that Tibetan samples reflect the highest diverse level of hordein phenotypes when compared to samples from Israel and Jordan. This high degree of polymorphism supports the hypothesis that Tibet is one of the original centers of H. vulgare L.
