HSC-2 — Oryza sativa Indica Group

Summary

BGIOSGA012332 (HSC-2, OiHSP70) on chromosome 3 of Indica rice encodes a member of the Hsp70 family of ATP-dependent protein folding chaperones, with ATP hydrolase and heat shock protein binding activities. The gene is associated with protein refolding, the ERAD pathway, the ER unfolded protein response, and responses to heat, stress, and virus. It is linked to auxin transport and signaling, amino acid membrane transport, and localizes to the ER lumen, chloroplast membrane, cytoplasm, and nucleus. Associations with agronomic traits include heat tolerance, grain yield per plant, spikelet fertility, spikelet number, plant height, root length, leaf size, and photosynthetic rate. Related genes in other species are linked to drought tolerance, grain dimensions, and shoot and root biomass.
