MYB1 — Oryza sativa Indica Group

Summary

BGIOSGA000485 (MYB1, also known as OiMYB1 or SRM1) on chromosome 1 of Indica rice encodes a MYB transcription factor with sequence-specific DNA-binding and chromatin-binding activities. This gene is associated with pigmentation, regulation of phenylpropanoid metabolism, anthocyanin anabolism, anther development, anther wall tapetum development, pollen development, response to auxin, response to cold, activation of salinity response, and upregulation of response to thirst. Associations with grain length, grain size, hull color, and salt stress tolerance have been reported. The encoded protein localises to both the nucleus and cytosol. Studies of related genes in other species connect the family to tapetum development, leaf shape, and seed germination under salt stress.
