Abstract

Rhizopus stolonifer is an important post-harvest pathogenic fungus. Recent taxonomic findings based on morphological and growth characteristics led to a dramatic reduction in the number of accepted species within the genus. The aim of this study was to examine this situation with molecular markers. Twenty-nine R. stolonifer strains isolated from various locations and substrates were characterized by random amplified polymorphic DNA (RAPD) analysis. The numerical analysis of the RAPD data revealed four main clusters with extremely high dissimilarity values, but only low or moderate variability was observed within these groups. These results suggest a high genetic heterogeneity in the case of R. stolonifer: isolates of R. stolonifer var. stolonifer, R. stolonifer var. reflexus and R. niveus displayed species-level genetic distances, which gives rise to considerations that they might be separate species.
