In contrast to C(3) photosynthesis, the response of C(4) photosynthesis to water stress has been less-well studied in spite of the significant contribution of C(4) plants to the global carbon budget and food security. The key feature of C(4) photosynthesis is the operation of a CO(2)-concentrating mechanism in the leaves, which serves to saturate photosynthesis and suppress photorespiration in normal air. This article reviews the current state of understanding about the response of C(4) photosynthesis to water stress, including the interaction with elevated CO(2) concentration. Major gaps in our knowledge in this area are identified and further required research is suggested.
