Late blight pathogen on a leaf
Sebastian Schornack
NRP-159

This image, from research carried out in The Sainsbury Laboratory on the Norwich Research Park, shows an infection site of the potato late blight pathogen on a leaf. The spreading pathogen hyphae are red-fluorescently labelled. Living leaf tissues are green, dead tissues are dark. Microscopic analysis of infection structures allows us to understand the lifestyles of different pathogens. This pathogen colonises living tissues first, but later kills the plant cells and therefore is classified as a hemibiotrophic pathogen.
