Shared characteristics underpinning C4 leaf maturation derived from analysis of multiple C3 and C4 species of Flaveria.

ABSTRACT: Most terrestrial plants use C₃ photosynthesis to fix carbon. In multiple plant lineages a modified system known as C₄ photosynthesis has evolved. To better understand the molecular patterns associated with induction of C₄ photosynthesis, the genus Flaveria that contains C₃ and C₄ species was used. A base to tip maturation gradient of leaf anatomy was defined, and RNA sequencing was undertaken along this gradient for two C₃ and two C₄ Flaveria species. Key C₄ traits including vein density, mesophyll and bundle sheath cross-sectional area, chloroplast ultrastructure, and abundance of transcripts encoding proteins of C₄ photosynthesis were quantified. Candidate genes underlying each of these C
