MYB31 — Oryza sativa Indica Group

Summary

BGIOSGA022169, designated MYB31, encodes a R2R3-MYB transcription factor on chromosome 6 of indica rice. The protein contains a Myb DNA-binding domain and is localised to the nucleus, where it binds sequence-specific DNA and cis-regulatory regions. MYB31 is associated with the shikimate pathway, regulation of lignin anabolism, anthocyanin anabolism, pigmentation, green leaf volatile biosynthesis, anther wall tapetum development, circadian rhythm, and response to wounding. It is also linked to grain length, grain size, and hull colour. Studies of related genes in other species connect the family to traits including lignin and cellulose content, flavonoid content, leaf colour and rolling, seed weight and size, grain number, heat and cold tolerance, chlorophyll content, seed germination, and heterosis.
