Light doesn’t just help plants grow, it also strengthens their internal structure by tightening the connection between tissues. This added rigidity can actually slow growth, revealing a hidden balance between strength and expansion.

Light is widely recognized as a key factor in plant growth, but scientists are still uncovering the details of how it works. Researchers at Osaka Metropolitan University have now identified a previously unknown process that helps explain how light influences plant development.

Light increases adhesion between plant tissues.
