HSP70 — Solanum lycopersicum

Summary

SOLYC12G042560.3, the tomato HSP70 gene on chromosome 12, encodes a heat shock 70 kDa protein family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. This gene is associated with diverse biological processes including autophagy in response to ER stress, pigment accumulation, flower formation, strigolactone anabolism, and membrane bending. It is linked to traits such as drought tolerance, photosynthetic rate, chlorophyll content, quantum yield, photochemical quenching, germination rate, amino acid content, and flower abortion. The encoded protein localizes to the cytoplasm, chloroplast membrane, ER lumen, and axonemal central pair projection. Studies of related genes in other species link the HSP70 family to protein processing and stress responses.
