CSA — Oryza sativa Indica Group

Summary

BGIOSGA020819 (CSA) on chromosome 6 of Indica rice encodes an R2R3-MYB transcription factor with RNA polymerase II-specific DNA-binding and chromatin-binding activities. The gene is associated with pigmentation, anthocyanin and lignin anabolism, anther and pollen development, stomatal movement, and responses to auxin, abscisic acid, cold, salinity, and thirst. It has been linked to grain length, grain size, hull color, leaf senescence, and UV-B tolerance. The protein localizes to the nucleus. Studies of related genes in other species connect the family to traits including seed weight, grain number, heat and drought tolerance, chlorophyll and flavonoid content, leaf angle and shape, and heterosis.
