MYB27 — Oryza sativa Indica Group

Summary

BGIOSGA033533, designated MYB27 (synonyms OiMYB27, ATMYB59-3), encodes a sequence-specific DNA-binding transcription factor on chromosome 11 of Indica rice. The protein localises to the nucleus and cytosol and is associated with the regulation of DNA-templated transcription, pigmentation, anthocyanin anabolism, and responses to stress, absence of light, and potassium ion levels. In this species, MYB27 has been connected to both abiotic and biotic stress responses. The gene is linked to grain size, grain length, and hull colour traits, as well as to salinity, drought, and ABA responses. Associations with potassium concentration, stomatal closure, root elongation, leaf and cell size, and resistance to pathogens and insects have also been reported. Studies of related genes in other species link the family to root growth, cadmium tolerance, leaf senescence, calcium homeostasis, and nematode resistance.
