🌱🧬How do plant cells sense low water? A protein called SAM8. Normally hydrated and dispersed. Under water deficit, hydration weakens and SAM8 condenses.
These condensates trap RNA export factors, reprogramming translation. A direct water potential sensor. @nature.com www.nature.com/articles/s41...
Plants sense water deficiency through SAM8 protein condensation, which responds to reduced hydration and triggers stress adaptation by altering RNA export and gene translation.
