CSA — Oryza sativa Indica Group

Summary

BGIOSGA000003 (CSA) on Indica rice chromosome 1 encodes an uncharacterized protein with a Myb domain, SANT/Myb domain, and Homeodomain-like superfamily, possessing RNA polymerase II cis-regulatory region sequence-specific DNA binding and DNA-binding transcription factor activity. It is associated with plant epidermis development, pigmentation, anthocyanin anabolism, regulation of phenylpropanoid and lignin metabolism, shikimate metabolism, green leaf volatile biosynthesis, anther and pollen development, stomatal movement, circadian rhythm, response to auxin, and upregulation of responses to thirst and salinity. The gene is linked to grain length, grain size, and hull color. Studies of related genes in other species connect the family to rolled leaf, flavonoid content, cellulose content, leaf color, seed weight, leaf angle, lignin content, heterosis, heat tolerance, seed size, grain number, chlorophyll content, seed germination, and salt tolerance.
