HSP70 — Cucumis melo

Summary

MELO3C022783.2, symbol HSP70 (CmHSP70) on melon chromosome 10, encodes a protein belonging to the UPF0220 domain family. The gene is associated with endosome-to-vacuole transport via the multivesicular body sorting pathway and with photosynthetic rate, a trait centred on CO2 exchange. Studies of related genes in other species link the HSP70 family to a wide range of agronomic traits, including plant height, fruit length and size, seed weight and size, root fresh and dry weight, leaf trichome density, leaf water potential, chlorophyll content, net photosynthetic rate, quantum yield, photochemical quenching, stomatal resistance, germination rate, drought tolerance, hydrogen peroxide content, proline content, amino acid content, lignin content, zinc concentration, and flower abortion. The family has also been connected to phenotypes such as clim-pet9, clim-aet2, clim-pet10, and clim-aet4.
