Description
Ilya Naydov and co-authors report a 2024 plant study on what happens inside leaves after the light goes off. A pool of fat-like molecules in the leaf stores charge from light work, then drains in the dark. That drain needs oxygen, but the exact routes have long been debated.
Working with pea leaf parts, the team tracked a glow signal that mirrors the state of the pool over seconds and minutes. The drain came in two phases: a fast one tied to flow onward in the chain, and a slow one tied to oxygen. A blocker of one leaf enzyme slowed the slow phase. Tests with a common reactive gas showed it can speed the drain when it builds up.
