CBF3 — Brachypodium distachyon

Summary

BdCBF3 (BRADI_1G57970V3) on chromosome 1 of Brachypodium distachyon encodes a DNA-binding transcription factor of the AP2/ERF domain family, specifically the DRE1A-I subfamily. It is annotated to DNA binding and transcription factor activity, localises to the nucleus, and is associated with cold acclimation and response to cold. Studies of related genes in other species link the family to winter survival, cold and salinity tolerance, drought tolerance, grain yield, relative yield, spikelet fertility, root dry weight and length, germination rate, chlorophyll content, and quantum yield. These transferred associations indicate that the BdCBF3 family is connected to multiple abiotic stress tolerances and agronomic performance traits, though direct functional evidence in Brachypodium is limited to its association with cold-responsive transcription.
