MYB — Oryza sativa Indica Group

Summary

BGIOSGA002364 (OiMYB) on chromosome 1 of Indica rice encodes a protein with SANT/Myb and homeodomain-like domains, localizes to the nucleus, and exhibits RNA polymerase binding, sequence-specific DNA binding, and transcriptional co-regulator activity. This gene is associated with diverse biological processes including circadian regulation of gene expression, photoperiodic flowering, pigmentation, meristem development, leaf senescence, dedifferentiation, regeneration, cell cycle control, calcium signaling, phospholipid breakdown, and green leaf volatile biosynthesis. It has been linked to agronomically important traits such as grain length, grain number, grain size, grain yield, hull color, rolled leaf, culm diameter, shoot fresh and dry weight, leaf chlorophyll content, photosynthetic rate, cold tolerance, temperature stress response, germination rate, callus induction, heterosis, and flowering time. Studies of related genes in other species connect the family to circadian rhythms, photomorphogenesis, thermotolerance, and stress responses.
