The earliest visual changes of leaf senescence occur in the chloroplast as chlorophyll is degraded and photosynthesis declines. Yet, a comprehensive understanding of the sequence of catabolic events occurring in chloroplasts during natural leaf senescence is still missing. Here, we combined confocal and electron microscopy together with proteomics and biochemistry to follow structural and molecular changes during Arabidopsis leaf senescence.

Article Synopsis
- Exposure of cyanobacterial or red algal cells to high light can cause a phenomenon known as excitonic decoupling, where the phycobilisome antennae (PBSs) become detached from their reaction centers.
- Research on Synechocystis sp. PCC 6803 demonstrates that strong light at specific wavelengths prompts this decoupling, often resulting in the disassembly or detachment of the PBSs from thylakoid membranes.
- The study suggests that local heat generated within PBSs disrupts energy transfer processes, which may affect how cyanobacteria adapt to light variations and other environmental challenges.
