Adaptive evolution of duplicated hsp17 genes in wild barley from microclimatically divergent sites of Israel

T. Zhang, Li, G. R., Yang, Z. J., and Nevo, E., Adaptive evolution of duplicated hsp17 genes in wild barley from microclimatically divergent sites of Israel, vol. 13, pp. 1220-1232, 2014.

Gene duplication is a major evolutionary driving force for establishing new gene functions. However, very little is known about the involvement of the structural divergence of recent duplicated genes in local adaptation. We evaluated the nucleotide variation of recent duplicated pair copies of the hsp17 locus for small heat shock proteins, namely, the older copy hsp17a and the younger copy hsp17b.
