ENGINEERED PEP CARBOXYLASE VARIANTS FOR IMPROVED PLANT PRODUCTIVITY

摘要

Variant phosphoenolpyruvate carboxylase (PEPC) genes are described. The encoded PEPC variants contain amino acid substitutions and have altered kinetic and/or regulatory properties with respect to wild-type PEPC. A variant PEPC gene may be expressed in a plant to improve one or more traits such as CO₂ assimilation rate, water use efficiency, and yield.
