MYB42 — Oryza sativa Indica Group

Summary

BGIOSGA018002 (MYB42) on chromosome 5 of Indica rice encodes a R2R3-MYB transcription factor with a Myb DNA-binding domain, localised to the nucleus. It is annotated for sequence-specific DNA binding and transcription regulator activity. The gene is associated with positive regulation of anthocyanin anabolism, the shikimate pathway, pigmentation, regulation of lignin anabolism, green leaf volatile biosynthetic process, circadian rhythm, and response to wounding. It has also been connected to hull color, grain length, grain size, and seed and flower phenotypes. Studies of related genes in other species link the family to traits including flavonoid content, lignin content, leaf shape, leaf color, seed weight, seed size, grain number, heat tolerance, and heterosis.
