HSP70 — Solanum lycopersicum

Summary

SOLYC11G020040.2, designated SlHSP70-7 on tomato chromosome 11, encodes a member of the heat shock protein 70 (HSP70) family, a chaperone with ATP hydrolase activity that binds ATP and other heat shock proteins, and is associated with protein folding. The gene is associated with numerous biological processes including hydrogen peroxide metabolism, autophagy in response to ER stress, and membrane localisation. It has been linked to a wide range of agronomically important traits, including drought tolerance, stay green, canopy temperature, cell membrane stability, flower abortion, leaf temperature, chlorophyll content, net photosynthetic rate, quantum yield, photochemical quenching, stomatal resistance, fruit color and size, germination rate, root number and length, lateral root number, stem diameter, leaf curling and shape, inflorescence number, and amino acid, cytokinin and protein content. The encoded protein localises to the ER lumen, chloroplast stroma, mitochondria, cytoplasm and nucleus.
