SPS2 — Cucumis sativus

Summary

CSA_2G401440, also known as SPS2, encodes a sucrose-phosphate synthase, an enzyme with sucrose-phosphate synthase activity, sucrose synthase activity, and transglycosidase activity. In cucumber, this gene is associated with a wide range of biological processes including threonine metabolism, nucleotide-sugar metabolism, stachyose anabolism, phloem unloading, nectar secretion, sex determination, regulation of carbohydrate metabolism, sucrose anabolism, glucose metabolism, chlorophyll metabolism, hormone anabolism, lipogenesis, pigmentation, photoprotection, regulation of photosynthesis, adventitious root development, regeneration, and carotenoid anabolism. It is linked to numerous agronomically important traits such as fruit weight, length, size and dry weight, sugar, starch, protein and carotene content, plant height, stem length and diameter, leaf thickness, seedling vigor, drought tolerance, pollen fertility, heterosis, and photosynthetic parameters including net photosynthetic rate, quantum yield, transpiration rate and stomatal resistance. The encoded protein localises to both the cytosol and nucleus.
