KEY GENES. “Positive selection for 51 genes was detected after the split from terrestrial monocots based on a maximum likelihood approach. In the present analysis, many of the identified PSGs are involved in the central biological pathways of translation, photosynthesis, and glycolysis.” (PSGs= positively selected genes).
