PPC — Solanum tuberosum

Summary

PPC1 (PGSC0003DMG400015385) on potato chromosome 12 encodes a phosphoenolpyruvate carboxylase (EC 4.1.1.31), a cytosolic enzyme with a PEP_COase domain. In potato, PPC1 is associated with photosynthesis, CAM photosynthesis, phloem sucrose loading, starch metabolism, cell wall polysaccharide anabolism, and amino acid and gibberellin biosynthesis. It has been linked to traits including starch digestibility, carbohydrate, glucose, nitrogen, sugar and chlorophyll content, photosynthetic rate, respiration rate, water use efficiency, stomatal resistance and opening, and seed weight. Studies of related genes in other species connect the family to drought tolerance, net photosynthetic rate, transpiration rate, root and shoot biomass, leaf dimensions, fruit size, pollen fertility, and flavonoid, lycopene, proline and protein content.
