The E3 ligase HRD1 enhances plant antiviral immunity by targeting viral movement proteins.

Summary: Plants have a clever way to fight off viruses! Just like humans have immune systems, plants have special tools to protect themselves. Scientists discovered a plant protein called HRD1 that acts like a security guard. When a virus tries to spread from one plant cell to another using special "movement proteins," HRD1 grabs these viral proteins and tags them for destruction. The plant's waste disposal system then chops them up. By boosting this security guard protein, plants can stop viruses in their tracks, keeping the plant healthy!
