From around 30 million years ago a more efficient version of photosynthesis known as the C4 pathway evolved in the sub-tropics and tropics. Due to its phenotypic complexity C4 photosynthesis is considered one of the most remarkable examples of convergent evolution as it is found in multiple lineages in both the monocotyledons and dicotyledons. Using Cleome gynandra, the closest C4 species to Arabidopsis, we have developed a spatiotemporal transcriptome dataset. Patterns of C4 genes expression have been isolated during leaf development and within cells. Compared with distant C4 lineages, those data will inform gene regulatory networks participating in initiation and maintenance of this particular form of photosynthesis.
