摘要
最近的两项研究重新研究了光呼吸作为一种光保护机制的现象。Smith 等人提出，叶绿体 ATP 合酶的负反馈调节减轻是一种替代假说。Von Bismarck 等人讨论了光呼吸功能受损的突变体如何通过下调光合作用和复杂的新陈代谢重新安排，更好地应对波动光（FL）环境。
Photorespiration - emerging insights into photoprotection mechanisms.
Two recent studies reinvestigated the phenomenon of photorespiration as a photoprotective mechanism. Smith et al. suggest alleviated negative feedback regulation of chloroplast ATP synthase as an alternative hypothesis. Von Bismarck et al. discuss how photorespiration-impaired mutants cope somewhat better with fluctuating light (FL) environments because of downregulated photosynthesis and complex metabolic re-routing.
