Cross species selection scans identify components of C4 photosynthesis in the grasses.

ABSTRACT: C₄ photosynthesis is perhaps one of the best examples of convergent adaptive evolution with over 25 independent origins in the grasses (Poaceae) alone. The availability of high quality grass genome sequences presents new opportunities to explore the mechanisms underlying this complex trait using evolutionary biology-based approaches. In this study, we performed genome-wide cross-species selection scans in C₄ lineages to facilitate discovery of C₄ genes. The study was enabled by the well conserved collinearity of grass genomes and the recently sequenced genome of a C₃ panicoid grass, Dichanthelium oligosanthes This method, in contrast to previous studies, does not rely on any a priori knowledge of the genes that contribute to biochemical or anatom
