PGM — Cicer arietinum

Summary

CaPGM (LOC101500018) on chickpea chromosome 6 encodes a phosphoglycerate mutase, a member of the histidine phosphatase superfamily with a phosphoglycerate mutase domain. In chickpea, this gene is associated with responses to nitrite, nitrate, and water, as well as secretion, and its product localizes to the plastid. Associations with plant dry weight, flower color, seed coat color, and chlorophyll content have been noted. Studies of related genes in other species link the family to sucrose and starch content, seed maturation, low-temperature stress response, photochemical quenching, root morphology, freezing tolerance, and leaf sucrose and starch content, though these relationships are not yet established in chickpea.
