Abstract
Isozyme variation of 70 endophytic Phyllosticta isolates representing four species from coniferous hosts and two species from angiospermous hosts was examined using starch gel electrophoresis of ten enzymes. All enzymes were polymorphic among species and each electromorph was restricted to a single host. Strains of Phyllosticta pseudotsugae were most diverse and separated into seven phenotypes. In Ph. cryptomeriae five phenotypes and in Ph. abietis two phenotypes were detected. The remaining species (Ph. multicorniculata, Ph. ampelicida, Ph. pyrolae) were monomorphic. Interspecific variation was always very high, with differences in at least 70% of the electromo...
