PPC — Sorghum bicolor

Summary

SbPPC (SORBI_3002G167000) on sorghum chromosome 2 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 phloem sucrose loading, stomatal opening, seed germination, leaf development, cell division, TCA cycle, amino acid anabolism, autotrophy, brassinosteroid-mediated signalling, and cellular response to phosphate starvation. It localises to the cytosol, chloroplast stroma, mitochondria, plasmalemma, apoplast, plant-type vacuole, Golgi complex, and plasmodesmata. SbPPC is linked to photosynthetic rate, grain filling period, anthesis time, amino acid content, nitrate uptake, leaf chlorosis, stomatal resistance, root morphology, and seedling growth traits. Studies of related genes in other species connect the family to salt tolerance, drought tolerance, phosphate starvation response, seed development, malate synthesis, starch and sucrose accumulation, and nitrogen metabolism.
