HSP70 — Cucumis sativus

Summary

CsHSP70 (CSA_5G387940) on cucumber chromosome 5 encodes a transmembrane protein 50A, a member of the UPF0220 family. The gene is associated with endosome-to-vacuole transport via the MVB sorting pathway, protein oxidation, secondary metabolite biosynthesis, sucrose metabolism, chlorophyll fluorescence, leaf senescence, cell death, response to heat, signal transduction, and homeostasis. It is also linked to photosynthetic rate and membrane localisation. Studies of related genes in other species connect the family to traits including plant height, fruit length and size, seed weight and size, germination rate, root fresh and dry weight, leaf trichome density, leaf water potential, stomatal resistance, net photosynthetic rate, quantum yield, photochemical quenching, chlorophyll content, hydrogen peroxide and proline content, amino acid and lignin content, zinc concentration, flower abortion, and drought tolerance.
