PFP-ALPHA — Solanum tuberosum

Summary

PGSC0003DMG400010007, designated StPFP-ALPHA on potato chromosome 4, encodes the alpha subunit of the pyrophosphate-dependent phosphofructokinase complex, a member of the phosphofructokinase domain family with diphosphate-fructose-6-phosphate 1-phosphotransferase and 6-phosphofructokinase activities. The gene is associated with carbohydrate metabolism, including sucrose and starch anabolism and breakdown, fructose 6-phosphate metabolism, the pentose-phosphate shunt, and responses to fructose, glucose, and sucrose. It is linked to regulation of growth, cell communication, RNA transport, and pH reduction. The protein localises to the cytosol, chloroplast stroma, mitochondria, plasmodesmata, and the pyrophosphate-dependent phosphofructokinase complex. Associations with agronomic traits include starch content, amylose content, sucrose content, glucose content, chlorophyll content, photosynthetic rate, respiration rate, and root morphology.
