Model building of the 3D structure of rice MATE protein LOC_Os01g49120. a, b Eighteen critical amino acid sites responsible for both functional divergence and positive selection and 5 sites responsible for coevolution are shown to a varying degree. The figure was produced using the Phyre2 and pyMOL programs. The amino acid sites responsible for both functional divergence and positive selection are colored red, while those responsible for coevolution are colored yellow
