MYBS3 — Oryza sativa Indica Group

Summary

BGIOSGA003931 (MYBS3) on chromosome 1 of Indica rice encodes a R2R3-MYB transcription factor with DNA-binding, transcription cis-regulatory region binding, protein homodimerization activity, and zinc binding. It is associated with diverse biological processes including pigmentation, anthocyanin biosynthesis, leaf senescence, flower development, lateral root development, cellular auxin homeostasis, response to sucrose, gibberellin, ethylene, salicylate, and absence of light, as well as green leaf volatile biosynthesis and regulation of transcription. The gene is linked to grain length, grain size, and hull color traits. Related genes in other species are associated with seed weight, grain number, grain yield, seed germination, heat and cold tolerance, chlorophyll content, leaf angle, and flavonoid, lignin, and cellulose content.
