## TL;DR

This paper explains how a protein called plastid lipocalin helps plants manage excess light energy by stabilizing a mismatch between a light-harvesting complex and the thylakoid membrane.

## Contribution

The paper introduces a novel mechanism involving lipocalin-mediated hydrophobic mismatch for sustained nonphotochemical quenching.

## Key findings

- Plastid lipocalin stabilizes hydrophobic mismatch between the light-harvesting complex and the thylakoid membrane.
- This stabilization sustains nonphotochemical quenching in plants.

## Abstract

The plastid lipocalin sustains nonphotochemical quenching by stabilizing hydrophobic mismatch between the major light harvesting complex and the thylakoid membrane.
