PFK — Solanum tuberosum

Summary

StPFK (PGSC0003DMG400017413) on potato chromosome 7 encodes a phosphofructokinase with 6-phosphofructokinase and diphosphate-fructose-6-phosphate 1-phosphotransferase activities, metal binding and ATP binding. The gene is associated with glycolytic process, fructose 6-phosphate metabolism, sucrose and starch anabolism, carbohydrate metabolism, response to glucose, cellular response to hypoxia, and NO storage. It has been linked to root epidermal cell differentiation and sugar homeostasis. The product localises to the cytosol, cytoplasm and plasmalemma. Studies of related genes in other species connect the family to hexose content, fruit color, leaf size, photochemical quenching, root morphology traits, and strongly reduced root length with reduced PFK activity.
