SPS — Solanum tuberosum

Summary

PGSC0003DMG401019060, the potato SPS gene on chromosome 11, encodes a sucrose-phosphate synthase isoform C, an enzyme with sucrose-phosphate synthase and transglycosidase activities. This gene is associated with sucrose anabolism and breakdown, starch anabolism, carbohydrate metabolism, phenylpropanoid anabolism, ALA metabolism, NO storage, circadian rhythm, and signal transduction. It has been connected to agronomically important traits including starch yield and content, sugar content, protein content, chlorophyll content, respiration rate, and plant height. Studies of related genes in other species link the family to sucrose-phosphate synthase activity (EC 2.4.1.14).
