HSP70 — Solanum lycopersicum

Summary

SOLYC11G013550.2, designated SlHSP70, encodes a protein belonging to the UPF0220 domain family on tomato chromosome 11. The gene is associated with a broad range of biological processes including heat dissipation, thermomorphogenesis, autophagy in response to ER stress, membrane bending, pigment accumulation, flower formation, and oospore formation. It has been linked to several agronomically important traits such as drought tolerance, photosynthetic rate, quantum yield, chlorophyll content, stomatal resistance, fruit size, germination rate, leaf water potential, leaf trichome density, and flower abortion. Studies of related genes in other species connect the family to seed weight, seed size, plant height, root fresh and dry weight, fruit length, and hydrogen peroxide content.
