MYB — Brachypodium distachyon

Summary

BdMYB (BRADI_2G34670V3) on chromosome 2 of Brachypodium distachyon encodes a protein with a Myb domain, SANT domain, and homeodomain-like superfamily, with sequence-specific DNA binding, RNA polymerase binding, and transcriptional co-regulator activities, localised to the nucleus. This gene is associated with circadian rhythm regulation, including entrainment, positive regulation of gene expression, and photoperiodic flowering. It is also linked to stomatal closure, anther development, chlorophyll fluorescence, the MAPK cascade, virus-induced PTGS, green leaf volatile biosynthesis, and alcohol and fatty alcohol anabolism. Associations with agronomic traits include flowering time, drought tolerance, stripe rust response, photosynthetic rate, leaf dry weight, and temperature stress responses. Studies of related genes in other species connect the family to circadian clock period, hypocotyl elongation, thermotolerance, cold stress response, biomass, leaf area, and anthocyanin and phenylpropanoid biosynthesis.
