C 4 photosynthesis is nature's response to CO 2 limitations, and evolved recurrently in several groups of plants. To identify genes related to C 4 photosynthesis, Huang et al. looked for evidence of past episodes of adaptive evolution in the genomes of C 4 grasses. They identified a large number of candidate genes that evolved under divergent selection, indicating that, besides alterations to expression patterns, the history of C 4 involved strong selection on protein-coding sequences.
