Figure 2

Phylogeny of C4 enzyme genes and their isoforms in sorghum, rice, maize and Arabidopsis. Thick branches show C4 enzyme genes. Bootstrap percentage values are shown as integers; Ka/Ks ratios are shown as numbers with fractions, or underlined when >1. In the gene IDs, Sb indicates Sorghum bicolor, Os indicates Oryza sativa, Zm indicates Zea mays, and At indicates Arabidopsis thaliana. (a) PEPC; (b) PPCK; (c) NADP-MDH; (d) NADP-ME; (e) PPDK; (f) PPDK-RP; (g) CA.
