PGM — Phaseolus vulgaris

Summary

PHAVU_007G064900, designated PvPGM, encodes a phosphoglucomutase enzyme that requires magnesium binding for its activity. This gene is associated with carbohydrate metabolism, including starch anabolism and breakdown, sucrose anabolism, and glucose metabolism. It is associated with nitrogen fixation, detection of gravity, and response to cold. The protein localizes to the chloroplast stroma and envelope, stromules, apoplast, and cytosol. Associations with phenotypes include photosynthetic capacity, starch metabolism, seed oil content, gravitropic and hydrotropic responses, leaf growth pattern, hexose and raffinose accumulation, and juvenile phase length. Studies of related genes in other species link the family to starch synthesis and deficiency.
