MYB31 — Oryza sativa Indica Group

Summary

BGIOSGA022174, designated MYB31 and also known as OiR2R3-MYB, encodes a R2R3-MYB transcription factor on chromosome 6 of Indica rice. The protein contains a Myb DNA-binding domain and a SANT/Myb domain, localises to the nucleus, and exhibits sequence-specific DNA binding and transcription factor activity. MYB31 is associated with the shikimate pathway, pigmentation, regulation of lignin anabolism, green leaf volatile biosynthetic process, anther wall tapetum development, anthocyanin anabolism, regulation of gene expression, downregulation of transcription, circadian rhythm, response to wounding, and DNA-dependent transcription. It has also been linked to hull color, grain length, and grain size. Studies of related genes in other species connect the family to traits including lignin content, flavonoid content, rolled leaf, leaf color, seed weight, seed size, grain number, chlorophyll content, heat tolerance, and cold tolerance.
