HSP70 — Solanum lycopersicum

Summary

SOLYC11G066100.2, the tomato HSP70 gene on chromosome 11, encodes a heat shock 70 family protein with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It is associated with diverse biological processes including autophagy in response to ER stress, pigment accumulation, flower formation, strigolactone anabolism, and membrane bending. The gene has been linked to agronomically important traits such as drought tolerance, photosynthetic rate, chlorophyll content, quantum yield, germination rate, flower abortion, and amino acid content. Its product localizes to multiple cellular compartments including the ER lumen, chloroplast membrane, tonoplast, cytoplasm, and nucleus.
