PGSC0003DMG400001912 — Solanum tuberosum

Summary

PGSC0003DMG400001912 on potato chromosome 00 encodes a phosphoglucosamine mutase, an enzyme with phosphoglucomutase and phosphomannomutase activity that binds metal ions. This gene is associated with starch biosynthesis and regulation of starch metabolism, as well as sucrose anabolism and breakdown, carbohydrate transport, and pyruvate metabolism. It has been connected to cell wall polysaccharide anabolism, vitamin A and catecholamine anabolism, and hormone metabolism. Associations with agronomically important traits include starch concentration, amylose content, reducing sugar content, sucrose content, glucose content, and amino acid content. The gene is also linked to net photosynthetic rate, stomatal opening, phosphorus content, and seed weight. The encoded protein localises to the chloroplast stroma and cytosol, and is associated with root gravitropism, seed development, and responses to abiotic stimuli including water.
