Abstract

Phosphoenolpyruvate carboxykinase (PEPCK) is an enzyme of the lyase family utilized in the gluconeogenesis pathway in plants. It converts oxaloacetate into Phosphoenolpyruvate (PEP) and carbon dioxide. PEPCK acts as a prime decarboxylase cytosolic enzyme and may have exhibited a positive response against salinity (main abiotic stress) stress in certain plants. Transgenic plants (C3) with high-level expression of C4 enzymes PEPC or PEPCK can serve as a perfect example for increasing the crop photosynthetic capacity through genetic engineering. In this review, we have focused on the recent advances in the utilization of the PEPCK gene and its role in increasing photosynthesis as well as in abiotic stress tolerance.
