DREB2B — Brachypodium distachyon

Summary

BRADI_2G29960V3 (DREB2B, BdAP2/EREBPPROTEIN) on chromosome 2 encodes a protein with an AP2/ERF DNA-binding domain, possessing sequence-specific DNA binding and transcription cis-regulatory region binding activities. This gene is associated with the upregulation of wax anabolism, cuticle anabolism, and responses to abscisic acid, ethylene, heat, salinity, osmotic stress, and drought. It is linked to chlorophyll fluorescence, photosynthetic rate, and leaf dry weight. The encoded protein localises to the nucleus. Related genes in other species are associated with drought recovery, heat tolerance, cold tolerance, salinity tolerance, water use efficiency, biomass yield, anthesis-silking interval, seed longevity, and raffinose and proline content, though these associations are not yet established in Brachypodium distachyon.
