PPC — Solanum tuberosum

Summary

StPPC (PGSC0003DMG400021264) on potato chromosome 10 encodes a phosphoenolpyruvate carboxylase (EC 4.1.1.31) with phosphoenolpyruvate carboxylase activity, belonging to the PEP_COase family. In potato, StPPC is associated with photosynthesis, C4 photosynthesis, malate secretion, phloem sucrose loading, photorespiration, the TCA cycle, autophagy, hormone metabolism, response to water, and Pi homeostasis. It is linked to carbohydrate content, sugar content, photosynthetic rate, respiration rate, stomatal resistance, stomatal opening, and drought tolerance. The protein localises to the apoplast and cytosol. Studies of related genes in other species connect the family to traits including starch content, net photosynthetic rate, water use efficiency, chlorophyll content, plant height, root weight, seed weight, and nitrogen content.
