HSP70 — Brachypodium distachyon

Summary

BRADI_2G46937V3 (HSP70) on chromosome 2 of Brachypodium distachyon encodes a heat shock 70 kDa protein family member with ATP-dependent protein folding chaperone activity, heat shock protein binding, ATP hydrolase activity, and ATP binding. The gene is associated with protein refolding, the ERAD pathway, the unfolded protein response (erUPR), heat acclimation, response to heat and stress, auxin transport and signaling, basipetal and polar auxin transport, amino acid membrane transport, virus-induced PTGS, and response to virus. The product localizes to the ER chaperone complex, ER lumen, chloroplast membrane, membrane, cytoplasm, and nucleus. Studies of related genes in other species link the HSP70 family to heat tolerance, drought tolerance, water use efficiency, transpiration rate, stomatal resistance, leaf water potential, root and shoot fresh and dry weight, root length, chlorophyll and carotenoid content, spikelet number, sugar content, and heterosis.
