PGM — Pisum sativum

Summary

PSAT6G201960 (PGM, also known as PGMP) encodes a phosphoglucomutase (EC 5.4.2.2) with magnesium binding activity, belonging to the alpha-D-phosphohexomutase superfamily. In garden pea (Pisum sativum), this gene is associated with starch and sucrose biosynthesis and metabolism, the pentose-phosphate shunt, lignin anabolism, and glucose metabolism. It is linked to detection of gravity, geotropism, root gravitropism, and hydrotropism, as well as response to cold, signal transduction, and metabolic burst. The encoded protein localizes to the chloroplast stroma, chloroplast envelope, stromule, apoplast, and cytosol. Associations with traits include starch content, sucrose content, seed coat color, flower color, and oxidative stress response. Studies of related genes in other species link the family to starch synthesis and deficiency.
