HSP70 — Solanum lycopersicum

Summary

SOLYC01G103450.3, designated SlHSP70, encodes a member of the heat shock protein 70 (HSP70) family, containing chaperone DnaK and ATPase domains, and is associated with protein folding chaperone activity, heat shock protein binding, and ATP binding. This tomato gene on chromosome 1 is linked to thermomorphogenesis, heat dissipation, autophagy in response to ER stress, pigment accumulation, and flower formation. It is associated with drought tolerance, fruit size, germination rate, photosynthetic rate, chlorophyll content, flowering time, and seed growth and development. Associations also include leaf senescence, stomatal resistance, abscisic acid sensitivity, and root morphology. Studies of related genes in other species link the HSP70 family to chloroplast development, thermotolerance, and ethylene signaling.
