MYB — Brachypodium distachyon

Summary

BdMYB (BRADI_1G32330V3) on chromosome 1 of Brachypodium distachyon encodes a protein with Myb and SANT domains, and is annotated with sequence-specific DNA binding, RNA polymerase binding, and transcriptional co-regulator activities. It is localized to the nucleus. This gene is associated with circadian rhythm regulation, including upregulation of circadian rhythm, entrainment of the circadian clock, and circadian regulation of gene expression. It is also linked to photoperiodism and flowering, anther development, stomatal closure, chlorophyll fluorescence, green leaf volatile biosynthesis, the MAPK cascade, and virus-induced PTGS. Associations with alcohol and fatty alcohol anabolism, and regulation of secondary metabolism have been noted. Traits linked to this gene include drought tolerance, stripe rust, photosynthetic rate, leaf dry weight, and temperature stress response trait. Studies of related genes in other species connect the family to circadian clock period, hypocotyl elongation, thermotolerance, and anthocyanin biosynthesis.
