Description

Nora Flynn writes a 2025 commentary on how membrane fluidity helps plants repair their light-harvesting machinery. Sunlight powers photosynthesis through two photosystems, but the core of one, called PSII, burns out often and must be rebuilt.

A protein complex named FtsH pulls the worn parts from the membrane and shreds them. Flynn discusses a study in Arabidopsis plants missing parts of that complex. In heat, when membranes run more fluid, the worst defects faded away. In cold, when membranes stiffen, the same defects grew worse. The pattern suggests a loose membrane helps the repair crew reach its targets.
