title: Look before you leap: memoirs of a "cell biological" plant pathologist.
abstract: In this article, I recount how I became a plant pathologist and used clues derived from light and electron microscopy to direct my research on the interactions between plants and biotrophic fungi. Examples of the value of microscopic examination are described for investigations of host compatibility, the hypersensitive response, nonhost resistance, and the evolution of host-parasite specificity.
