title: Traces of strong selective pressures in the genomes of C4 grasses.
abstract: C4photosynthesis is nature's response to CO2limitations, and evolved recurrently in several groups of plants. To identify genes related to C4photosynthesis, Huang et al. looked for evidence of past episodes of adaptive evolution in the genomes of C4grasses. They identified a large number of candidate genes that evolved under divergent selection, indicating that, besides alterations to expression patterns, the history of C4involved strong selection on protein-coding sequences.
