HSP70 — Sorghum bicolor

Summary

SORBI_3009G1639190 (HSP70) on sorghum chromosome 9 encodes a heat shock protein 70 family member with ATP-dependent protein folding chaperone activity, heat shock protein binding, and ATP hydrolase activity. This gene is associated with protein refolding, the ERAD pathway, the unfolded protein response, detoxification, protein breakdown, pollen tube growth, programmed cell death, and responses to virus, stress, and heat. It is linked to heat tolerance, drought tolerance, and photosynthetic rate. The encoded protein localises to the ER chaperone complex, ER lumen, chloroplast membrane, cytoplasm, and nucleus. Studies of related genes in other species connect the family to plant dry weight, root fresh weight, leaf relative water content, shoot fresh weight, net photosynthetic rate, stomatal resistance, and root length.
