High temperatures trigger protective mechanism in plants to prevent damage.
The researchers found that at temperatures above 30°C, the parts of the plant responsible for photosynthesis change. The light-harvesting part of Photosystem II separates from the rest of the system and moves to a different location in the plant. This change helps protect the plant from getting damaged by too much light and heat. The separation and movement of these parts are reversible when the temperature is lowered. This process allows the plant to continue functioning well even in high-light conditions with elevated temperatures.
