MYB2 — Oryza sativa Indica Group

Summary

BGIOSGA026430 (MYB2, OiR2R3-MYB) on chromosome 7 of Indica rice encodes an uncharacterized protein with sequence-specific DNA binding and transcription cis-regulatory region binding activities. It is associated with the regulation of phenylpropanoid and shikimate metabolism, anthocyanin and pigment biosynthesis, and green leaf volatile production. The gene has been linked to anther and pollen development, floral organ senescence, and flower development regulation, as well as responses to jasmonic acid, viral infection, and abiotic stresses including salinity. It is associated with cell wall organization, circadian rhythm, and gene expression regulation. Associations with grain length, grain size, and hull color have been noted. Studies of related MYB family members in other species connect this gene family to leaf rolling, leaf angle, cellulose content, heat tolerance, grain number, and chlorophyll content.
