Genome-Wide Transcription Factor Binding in Leaves from C₃ and C₄ Grasses.

ABSTRACT: The majority of plants use C₃ photosynthesis, but over 60 independent lineages of angiosperms have evolved the C₄ pathway. In most C₄ species, photosynthesis gene expression is compartmented between mesophyll and bundle-sheath cells. We performed DNaseI sequencing to identify genome-wide profiles of transcription factor binding in leaves of the C₄ grasses Zea mays, Sorghum bicolor, and Setaria italica as well as C₃ Brachypodium distachyon In C₄ species, while bundle-sheath strands and whole leaves shared similarity in the broad regions of DNA accessible to transcription factors, the short sequences bound varied. Transcription factor binding was prevalent in gene bodies as well as promoters, and ma
