PGI — Phaseolus vulgaris

Summary

PHAVU_008G180200, designated PvPGI, encodes a glucose-6-phosphate isomerase with monosaccharide and carbohydrate derivative binding activity, belonging to the SIS_PGI domain family. This French bean gene on chromosome 8 is associated with glucose 6-phosphate metabolism, gluconeogenesis, glycolytic processes, starch breakdown and metabolism, nitrogen fixation, nodulation, and upregulation of flower development. The product localises to the chloroplast envelope, stroma, plastid, and cytosol. PvPGI is associated with starch synthesis and accumulation, transitory starch synthesis, carbon partitioning, leaf starch synthesis, photosynthetic capacity, cytokinin biosynthesis, seed development and yield, fatty acid content, flowering time, floral initiation, and growth. Studies of related genes in other species link the family to photosynthesis, plant growth, and fertility.
