What genes are involved in the adaptive intraspecies divergence of aegilops tauschii?

The coding sequences of 27,448 genes each of 72 accessions of Aegilops tauschii, representing the entire species range, were obtained using next generation sequencing of transcriptomes from leaf tissue. 9,660 of these genes exhibited high Ka/Ks values exceeding 0.8. 4,336 different GO terms were present in the annotations for this gene set, with 193 of them occurring statistically significantly more often among the genes with high Ka/Ks, indicating variation in what functions and processes were involved in the adaptive intraspecies divergence of A. tauschii. It was shown that A. tauschii genes with high Ka/Ks ratios are primarily those which help plants to adapt to different ecological conditions and respond to changing environments. Those genes whose allelic variation played an essential role in A. tauschii intraspecies divergence included R-Genes (marked with GO terms: GO:0043531, ADP binding, + GO:0051707, response to other organisms, + GO:0006952, defence response); as well as genes involved in photosynthesis, response to light stimulus, the respiratory electron transport chain, transcriptional regulation, microtubule motor activity, and the regulation of the jasmonic acid mediated signalling pathway, etc.
