Microscopic and molecular genetic analyses of morphological development of the actinomycete Actinoplanes missouriensis

Abstract

The survival strategy of members of the bacterial genus Actinoplanes is fascinating from morphological and evolutionary perspectives. A brief motile phase is incorporated in the filamentous and resting stages of the life cycle of Actinoplanes missouriensis. Spores either lie dormant or swim under different external conditions. This review presents microscopic observations and molecular genetic analyses of A. missouriensis morphological development. Selected examples of the characterization of developmental genes and their products are also introduced.
