New Insights Into the Evolution of C₄ Photosynthesis Offered by the Tarenaya Cluster of Cleomaceae.

ABSTRACT: Cleomaceae is closely related to Brassicaceae and includes C₃, C₃-C₄, and C₄ species. Thus, this family represents an interesting system for studying the evolution of the carbon concentrating mechanism. However, inadequate genetic information on Cleomaceae limits their research applications. Here, we characterized 22 Cleomaceae accessions [3 genera (Cleoserrata, Gynandropsis, and Tarenaya) and 11 species] in terms of genome size; molecular phylogeny; as well as anatomical, biochemical, and photosynthetic traits. We clustered the species into seven groups based on genome size. Interestingly, despite clear differences in genome size (2C, ranging from 0.55 to 1.3 pg) in Tarenaya spp., this variation was not consistent wit
