Genetic requirements for potassium ion-dependent colony spreading in Bacillus subtilis.

abstract：:A number of independently derived uracil-requiring mutant strains of the parent strain 168 were mapped by inter-mutant transformation crosses. Only a few of these mutant strains were found to be transformable. Studies were performed in which these transformable uracil-requiring mutant strains were used as the recipien...
