Anomalous Genetic Interactions observed in Bacillus subtilis


GENETIC transformation in B. subtilis has recently been reported by Spizizen1, but as yet no paper has appeared discussing genetic interaction between the cells of spore-bearing bacteria. In this communication, a new fact will be described which was discovered while attempting to cross auxotrophic mutants of B. subtilis K. It involves the de novo appearance of characters not present in the parent strains. The complete details of this work will be published elsewhere.
