HSP70 — Oryza sativa Japonica
Summary
OsHSP70 (OS02G0710900) on rice chromosome 2 encodes a heat shock 70 kDa protein family member with ATP-dependent protein folding chaperone, adenyl-nucleotide exchange factor, and ATP hydrolase activities. It is associated with protein refolding, denaturation, and import, the ERAD pathway, ER unfolded protein response, pigmentation, detoxification, and metabolic burst. The gene is linked to heat tolerance, thermotolerance, drought tolerance, and abiotic stress response, as well as traits including grain length and width, chlorophyll and carotenoid content, photosynthetic rate, water use efficiency, transpiration rate, root and shoot fresh and dry weight, leaf water potential, and heterosis. It localises to the ER lumen, ER chaperone complex, tonoplast, Golgi, and secretory vesicles. Studies of related genes in other species link the family to grain yield, spikelet fertility, plant height, and rust resistance.
