Perspectives on plant photorespiratory metabolism

Plant Biol (Stuttg). 2013 Jul;15(4):748-53. doi: 10.1111/j.1438-8677.2012.00693.x. Epub 2012 Dec 10.


Being intimately intertwined with (C3) photosynthesis, photorespiration is an incredibly high flux-bearing pathway. Traditionally, the photorespiratory cycle was viewed as closed pathway to refill the Calvin-Benson cycle with organic carbon. However, given the network nature of metabolism, it hence follows that photorespiration will interact with many other pathways. In this article, we review current understanding of these interactions and attempt to define key priorities for future research, which will allow us greater fundamental comprehension of general metabolic and developmental consequences of perturbation of this crucial metabolic process.
