MYB80 — Oryza sativa Indica Group

Summary

BGIOSGA002218 (MYB80, OiR2R3-MYB) on chromosome 1 of Indica rice encodes an uncharacterized protein with a Myb domain and SANT/Myb domain, and has DNA-binding transcription factor activity with cis-regulatory region sequence-specific DNA binding and chromatin binding activities. It is associated with pigmentation, regulation of lignin anabolism, anther wall tapetum development, anthocyanin anabolism, stomatal movement, response to auxin, DNA-dependent transcription, upregulation of transcription, salinity response, regulation of DNA-templated transcription, response to cold, and response to abscisic acid. The gene is linked to hull color, grain length, grain size, and the GRLG trait. Related genes in other species are linked to rolled leaf, cellulose content, leaf angle, leaf shape, heat tolerance, grain number, chlorophyll content, and salt tolerance.
