Fig. 8From: The draft genome of the C3 panicoid grass species Dichanthelium oligosanthes Amino acids under positive selection in C4 lineages. (a) PEPC and (b) PEPCK amino acid sequences for C3 and C4 grass species. Amino acids are color-coded according to their chemical properties: black, non-polar; red, polar; green, acidic; blue, basic. C4 amino acids are bolded. Figure modified from Christin et al. [4, 65]Back to article page
