The mode of submerged spore (SS) formation in Kitasatosporia setae was studied. A time course study of SS formation with pulse-labeling and radioautography demonstrated that at the tips of the hyphal branches, premature spore chains were produced and grew into short spore chains. Then the short spore chains were fragmented to yield SS. This was supported by the morphological changes observed by Nomarski differential interference microscopy, which showed that K. setae differs from Streptomyces griseus in the way SSs are formed.
