An Electron-Microscopic Study of Spores of Morphological Variants of Streptomyces erythreus strains

Abstract

THE morphological heterogeneity of lower fungi based on the different intensity of formation of aerial mycelium and conidia, was found in most of the representatives of the Fungi Imperfecti and was described by Hansen1 as the ‘dual phenomenon’. According to Lindegreen and Andrews2 the ‘dual phenomenon’ represents a case of simple heterocaryosis. Heterocaryosis is exhibited by Actinomycetes as well, as shown by Bradley and Lederberg3.
