DREB2A — Brachypodium distachyon

Summary

BRADI_2G04000V3 (BdDREB2A) on chromosome 2 of Brachypodium distachyon encodes a transcription factor with an AP2/ERF DNA-binding domain. It is associated with DNA binding and transcription cis-regulatory region binding, and is localized to the nucleus. The gene has been connected to responses to stress, heat, salinity, thirst, and defense, as well as to the ethylene-mediated signalling pathway and upregulation of DNA-dependent transcription. BdDREB2A is linked to drought tolerance. Studies of related genes in other species associate the family with salt, drought, osmotic stress, and temperature stress tolerance, as well as with traits including grain yield, plant height, root length, leaf chlorophyll content, biomass yield, and germination rate.
