HSP70 — Oryza sativa Indica Group

Summary

BGIOSGA034364 (HSP70) on chromosome 11 of Indica rice encodes an uncharacterized protein belonging to the Hsp70 family and containing an ATPase NBD domain, with annotated molecular functions including ATP-dependent protein folding chaperone, ATP hydrolase activity, heat shock protein binding, and ATP binding. The gene is associated with protein refolding, the ERAD pathway, the erUPR, and responses to heat, stress, and virus. It has been linked to auxin transport and signaling, amino acid membrane transport, and localizes to the ER lumen, ER chaperone complex, chloroplast membrane, cytoplasm, and nucleus. Associations with agronomic traits include heat tolerance, grain yield, spikelet fertility, spikelet number, plant height, root length, and leaf size. Related genes in other species link the family to ER stress responses and protein quality control.
