C3 plants lose a significant part of previously fixed CO2 in the process of photorespiration. Reduction in photorespiration is expected to increase the productivity of crop plants and reduce the requirements for irrigation and fertilization. For more than ten years, research at our institute has focused on the genetic engineering of dicotyledonous crops plants toward improved CO2 fixation. In this paper, we summarize results from our work vis-a-vis reports from other laboratories and define future challenges. Furthermore, we introduce an alternative approach based on the installation of bypass of photorespiration in the chloroplast.
