Host-pathogen interactions between an obligate biotrophic pathogen, the powdery mildew Blumeria graminis tritici, and susceptible and resistant strains of wheat. This image shows a scanning electron micrograph (SEM) of a Blumeria spore(s) that has produced a germtube (gt) and appressorium (app). This specimen was rapidly frozen and freeze dried. We are combining SEM imaging with energy dispersive spectroscopy to study events critical to host penetration.
This image was collected by Brandon van Leer, FEI, Hillsboro OR, on uncoated material, using a Nova NanoLab 600 Dual Beam that uses a Sirion FEG electron column and is equipped with EDS chemical analysis.
Pictured: spore, germ tube and appressorium
