ERD2 — Brachypodium distachyon

Summary

BdERD2 (BRADI_1G03720V3) on chromosome 1 of Brachypodium distachyon encodes a member of the Hsp70 family of ATP-dependent protein folding chaperones, containing the characteristic HSP70 peptide-binding and ATPase domains. The gene is associated with diverse molecular functions including calcium-dependent phospholipid binding, DXP-synthase activity, and Hsp90 binding, and is linked to processes such as protein folding in the endoplasmic reticulum, cytosol-to-ER transport, RuBisCO assembly, and responses to humidity and salicylate. Associations with agronomically relevant traits include grain filling period, spikelet number, biomass yield, photosynthetic ability, and carotenoid content. The gene is also connected to cell cycle regulation, guard mother cell division, and chloroplast development. Related genes in other species are linked to leaf senescence, heat stress tolerance, and innate immunity.
