PPC1 — Cicer arietinum

Summary

LOC101497901, also known as CaPPC1 or PPC1 on chickpea chromosome 1, encodes a phosphoenolpyruvate carboxylase (PEPC) with phosphoenolpyruvate carboxylase activity, protein phosphorylated amino acid binding, and protein binding functions. It belongs to the PEP_COase family and contains a Pyrv/PenolPyrv_kinase-like domain. This gene is associated with phloem sucrose loading, the TCA cycle, autotrophy, embryogenesis, brassinosteroid-mediated signalling, and cellular response to phosphate starvation. It is linked to photosynthetic rate, nitrate uptake, salt tolerance, root morphology, seedling growth, plant growth and development, carbon and nitrogen metabolism, ammonium assimilation, malate synthesis, and starch and sucrose accumulation. The protein localises to the cytosol, chloroplast stroma, mitochondria, plasmalemma, apoplast, plant-type vacuole, plasmodesma, and Golgi complex. Studies of related genes in other species link the family to salt stress tolerance, phosphate deficiency response, and anaplerobic metabolism.
