HSP70 — Oryza sativa Indica Group

Summary

BGIOSGA011002 (symbol HSP70, OiHSP70) on chromosome 3 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 diverse biological processes including protein refolding, the ERAD pathway, the unfolded protein response (erUPR), auxin transport and signaling, pollen tube growth, and responses to heat, stress, and virus. It localizes to the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen, and axonemal central pair projection. Associations with agronomic traits include heat tolerance, grain yield, spikelet fertility, spikelet number, plant height, leaf size, root length, and photosynthetic rate. Related genes in other species are linked to drought tolerance, chlorophyll content, water use efficiency, and resistance to stem rust and stripe rust.
