Plant photorespiration is an essential prerequisite for oxygenic photosynthesis. This metabolic repair pathway bestrides four compartments, which poses the requirement for several metabolites transporters for pathway function. However, in contrast to the well-studied enzymatic steps of the core photorespiratory cycle, only few photorespiratory translocators have been identified to date. In this review, we give an overview of established and unknown plastidic transport proteins involved in photorespiration and intertwined nitrogen and sulfur metabolism, respectively. Furthermore, we discuss the evolutionary origin of the dicarboxylate translocators and the recently identified glycolate glycerate translocator.
植物光呼吸是有氧光合作用的必要前提。这种代谢修复途径跨越四个区室，这就对途径功能所需的几种代谢物转运体提出了要求。然而，与核心光呼吸循环中已被充分研究的酶促步骤不同，迄今为止仅鉴定出少数光呼吸转运体。在本综述中，我们分别概述了参与光呼吸以及相互交织的氮和硫代谢的已确定和未知的质体转运蛋白。此外，我们还讨论了二羧酸转运体的进化起源以及最近鉴定出的乙醇酸甘油酸转运体。
