The electrophoretic patterns of proteins extracted from spores and mycelium of two Drechslera species

Abstract

Electrophoresis of protein extracts from spores and mycelium of two Drechslera species (D. erythrospilum and D. teres) was carried out on polyacrylamide gels. Spores were harvested from V-8 juice agar and mycelium from V-8 juice broth cultures. One or two band differences were found between electrophoretic patterns of spore extract and mycelial extract depending on the species. Interspecies differences in patterns were no greater than intraspecies differences. The results are discussed, and it is suggested that the method of polyacrylamide gel electrophoresis of proteins is unsuitable as an aid to fungal taxonomy in its present state of development.
