SHD — Solanum lycopersicum

Summary

SlSHD (SOLYC07G047790.3) on tomato chromosome 7 encodes a member of the heat shock protein 90 (Hsp90) family, characterized by Hsp90, HATPase_C, and ribosomal S19e domains, and annotated with ATP-dependent protein folding chaperone activity. In tomato, SlSHD is associated with responses to yellow leaf curl virus, salinity tolerance, heavy metal tolerance, root biomass, and developmental regulation. The gene has been linked to diverse processes including cellular response to unfolded protein, base-excision repair, vesicle organization, respiratory burst in defense response, and mitochondrial protein import. Associations with traits include floral organ morphology, seed set, leaf water potential, temperature stress response, bacterial and viral disease responses, submergence tolerance, aphid response, and reproductive growth time. Studies of related genes in other species connect the Hsp90 family to thermotolerance, broad-spectrum disease resistance, and chloroplast function.
