Abstract excerpt

Photorespiration is essential for maintaining plant photosynthesis and growth under aerobic conditions. While environmental factors like light-dark transitions and high light modulate this pathway, the underlying molecular regulatory mechanisms remain unclear. Here, we report that the activity of phosphoglycolate phosphatase (PGLP), the first enzyme in the photorespiratory pathway, is redox-regulated in response...
