PGK — Brassica napus

Summary

BnPGK (DARMORV10_C06P53420.1) on chromosome C06 of oilseed rape encodes a phosphoglycerate kinase family protein with ADP and ATP binding, protein kinase activity, and metal binding. The gene is associated with the reductive pentose-phosphate cycle, glycolytic process, gluconeogenesis, starch and sucrose metabolism, galactolipid and lipogenesis, thylakoid membrane organization, stomatal closure, and responses to light, heat, glucose, bacterial molecules, cadmium, and ABA signaling. It localizes to the chloroplast stroma, cytosol, mitochondria, membrane, apoplast, vacuole, and plasmodesmata. BnPGK is linked to drought tolerance, proline content, salt tolerance, plant growth, autophagy regulation, and pollen tube growth polarity. Studies of related genes in other species connect the phosphoglycerate kinase family to carbohydrate, starch, and lignin content, and virus resistance.
