摘要

Ribulose-1,5-bisphosphate (RuBP) carboxylase/oxygenase (Rubisco) catalyzes two competing reactions, photosynthetic CO_2 fixation and photorespiratory carbon oxidation. Rubisco has a low rate of catalysis, and the in vivo rate of CO_2 fixation by Rubisco is additionally decreased by its low affinity for CO_2 and the competing -oxygenation reaction with O_2 (for a review, see Lorimer 1981). Because of this inefficiency, Rubisco is a rate-limiting factor for photosynthesis under some environmental conditions, such as high light and low CO_2. In addition, Rubisco is the most abundant leaf protein, and large amounts of N are invested in this protein. Therefore, genetic modification to enhance Rubisco efficiency in crops would have great agronomic importance as a prospect to improve potential photosynthesis. This paper discusses the possible approaches to photosynthetic improvement by the enhancement of Rubisco efficiency in rice.
