MYB — Oryza sativa Indica Group

Summary

BGIOSGA020708 (OiMYB) on chromosome 6 of Indica rice encodes a protein with Myb and SANT domains, and is annotated with DNA binding, RNA polymerase binding, and transcriptional co-regulator activities, localised to the nucleus. This gene is associated with a wide range of biological processes including circadian rhythm regulation, photoperiodic flowering, pigmentation, leaf senescence, meristem development, dedifferentiation, regeneration, cell cycle control, calcium signaling, phospholipid breakdown, and green leaf volatile biosynthesis. It has been linked to numerous agronomic traits such as grain yield, grain length, grain number, grain size, hull color, leaf chlorophyll content, photosynthetic rate, cold tolerance, temperature stress response, flowering time, culm diameter, shoot fresh and dry weight, germination rate, callus induction, heterosis, and rolled leaf. Studies of related genes in other species connect the family to circadian clock function, photomorphogenesis, thermotolerance, cold and heat stress responses, hypocotyl elongation, and biomass.
