HSP70 — Oryza sativa Indica Group

Summary

BGIOSGA034960 (HSP70) on chromosome 11 of Indica rice encodes an ATP-dependent protein folding chaperone with ATP hydrolase activity and heat shock protein binding, belonging to the Hsp70 family. This gene is associated with protein refolding, the ERAD pathway, the unfolded protein response in the endoplasmic reticulum, and responses to heat, stress, and virus. It is linked to auxin transport and signaling, as well as amino acid membrane transport. The encoded protein localizes to the ER lumen and chaperone complex, cytoplasm, nucleus, chloroplast membrane, tonoplast, and membrane. Agronomically, HSP70 is associated with heat tolerance, grain yield, spikelet fertility, spikelet number, plant height, root length, relative root length, and leaf size.
