Plant pathology: Deadly special deliveries
Nicholas J. Talbot1
Abstract
When attacking a plant, pathogens must deliver proteins into their victim's cells. The causal agent of potato late blight uses a system that is remarkably similar to that used by the malaria parasite in red blood cells.
To infect plants and cause disease, many microorganisms evade or subdue plant defences so that they can proliferate unhindered within the host's tissues1. For this purpose, pathogenic bacteria have systems to deliver 'effector' proteins directly into plant cells, where they interact with plant proteins and suppress defence mechanisms2.
