Photorespiration – emerging insights into photoprotection mechanisms
Trends in Plant Science(2024)
Abstract
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.
