SPP1 — Cucumis melo

Summary

MELO3C009570.2, also known as CmSPP1 or SPP1, encodes a sucrose-phosphate phosphatase (EC 3.1.3.24) and is associated with sucrose-phosphate synthase and sucrose synthase activities, as well as transglycosidase activity and magnesium binding. The gene is associated with sucrose anabolism and metabolism, nectar secretion, phloem transport, fruit ripening, and protein processing. It has been connected to traits including sucrose content, sugar content, seed viability, low temperature stress response, and plant growth and development. Localization evidence places the product in the cytosol, endoplasmic reticulum, plant-type vacuole, plasmodesma, plasma membrane, and nucleus. Studies of related genes in other species link the family to stomatal process-related traits and photochemical quenching.
