Young leaves of salt‐depleted Aeluropus litoralis Parl. plants show CO 2 fixation by the C 3 ‐carbon fixation pathway. No detectable activity of phosphoenol pyruvate (PEP) carboxylase was found. When A. litoralis plants were exposed to a NaCl solution, the leaves showed a high activity of PEP carboxylase as well as a significant CO 2 fixation by the C 4 ‐pathway. — Also in Zea mays L. and Chloris gayana Kunth., the presence of NaCl in the medium influences the balance between phosphoenol pyruvate carboxylase and ribulose‐1,5‐diphosphate carboxylase.
