The Conserved DNA Binding Protein WhiA Influences Chromosome Segregation in Bacillus subtilis.

abstract：:Cultures of recombination-deficient strains of Escherichia coli are composed of three classes of cells: (i) viable cells, which can undergo 20 or more generations, (ii) residually dividing cells, which can undergo fewer than 20 generations (probably an average of fewer than 6), and (iii) nondividing cells, which are i...
