PPC — Sorghum bicolor

Summary

SbPPC (SORBI_3003G100600) on sorghum chromosome 3 encodes a phosphoenolpyruvate carboxylase (EC 4.1.1.31) with phosphoenolpyruvate carboxylase activity, protein phosphorylated amino acid binding, and protein binding functions. This gene is associated with C4 photosynthesis, phloem sucrose loading, stomatal opening, leaf development, seed germination, cell division, TCA cycle, brassinosteroid-mediated signalling, and cellular response to phosphate starvation. It localises to the cytosol, chloroplast stroma, plasmalemma, mitochondria, apoplast, Golgi complex, plant-type vacuole, and plasmodesmata. Associations include grain filling period, photosynthetic rate, stomatal resistance, anthesis time, leaf chlorosis, nitrate uptake, root morphology, seedling growth, and plant stress response. Related genes in other species link the family to salt stress tolerance, phosphate deficiency response, and nitrate response.
