MYB — Brachypodium distachyon

Summary

BRADI_3G51757V3 (BdMYB) encodes a MYB-domain transcription factor with DNA-binding, RNA polymerase binding, and transcriptional co-regulator activities, localised to the nucleus. In Brachypodium distachyon, this gene is associated with circadian rhythm regulation, photoperiodic flowering, anther development, stomatal closure, chlorophyll fluorescence, green leaf volatile biosynthesis, and the MAPK cascade. It is also linked to alcohol and fatty alcohol anabolism, secondary metabolism regulation, and virus-induced post-transcriptional gene silencing. Associations with agronomic traits include leaf dry weight, photosynthetic rate, flowering time, drought tolerance, stripe rust resistance, and temperature stress response. Studies of related genes in other species connect the family to circadian clock function, photomorphogenesis, hypocotyl elongation, biomass accumulation, thermotolerance, cold and salt stress responses, and phenylpropanoid biosynthesis.
