C4 photosynthesis is nature’s response to CO2 limitations,
and evolved recurrently in several groups of plants. To
identify genes related to C4 photosynthesis, Huang et al.
looked for evidence of past episodes of adaptive evolution
in the genomes of C4 grasses. They identified a large
number of candidate genes that evolved under divergent
selection, indicating that, besides alterations to expression
patterns, the history of C4 involved strong selection
on protein-coding sequences.
