Description:
<jats:p>C<jats:sub>4</jats:sub>photosynthesis evolved multiple times independently from ancestral C<jats:sub>3</jats:sub>photosynthesis in a broad range of flowering land plant families and in both monocots and dicots. The evolution of C<jats:sub>4</jats:sub>photosynthesis entails the recruitment of enzyme activities that are not involved in photosynthetic carbon fixation in C<jats:sub>3</jats:sub>plants to photosynthesis. This requires a different regulation of gene expression as well as a different regulation of enzyme activities in comparison to the C<jats:sub>3</jats:sub>context. Further, C<jats:sub>4</jats:sub>photosynthesis relies on a distinct leaf anatomy that differs from that of C<jats:sub>3</jats:sub>, requiring a differential regulation of leaf development in C<jats:sub>4</jats:sub>. We summarize recent progress in the understanding of C<jats:sub>4</jats:sub>-specific features in evolution and metabolic regulation in the context of C<jats:sub>4</jats:sub>photosynthesis.</jats:p>
