Description
Zeno Guardini and six co-authors pinpoint which light-harvesting parts stack the membranes inside plant cells, in a study from twenty twenty-six. Green plant cells fold their inner membranes into stacks called grana. The stacks keep the two photosystems apart, which balances the flow of light energy between them.
By removing parts of the antenna family that serves the second photosystem, the team could test each part's role. Removing the whole antenna erased the stacks entirely. Removing single subgroups cut stacking by up to two-fifths. One part alone could partly restore stacks, while another made oversized stacks that fell apart in light. Energy spill between the systems tracked antenna loss more than stack shape.
