MYB — Oryza sativa Indica Group

Summary

BGIOSGA018757 (OiMYB) on chromosome 5 of Indica rice encodes a SANT/Myb domain-containing protein with DNA-binding transcription factor activity, RNA polymerase binding, and transcriptional co-regulator functions. It is localized to the nucleus. This gene is associated with regulation of circadian rhythm, photoperiodism and flowering, pigmentation, meristem development, leaf senescence, dedifferentiation, regeneration, cell cycle control, calcium signaling, green leaf volatile biosynthesis, and phospholipid breakdown. Associations with agronomic traits include grain length, grain number, grain size, grain yield, hull color, rolled leaf, culm diameter, shoot dry weight, leaf chlorophyll content, photosynthetic rate, cold tolerance, flowering time, callus induction, heterosis, and germination rate. Related genes in other species link the family to circadian clock gene expression, hypocotyl elongation, thermotolerance, cold stress response, biomass, and photomorphogenesis.
