We examined the pattern of FtsZ localization in a Bacillus
subtilis minCD mutant. When grown in minimal medium, the majority (~89%) of the minCD mutant cells with an FtsZ ring had a
single, medially positioned FtsZ ring. These results indicate that
genes in addition to minCD function to restrict the number
and position of FtsZ rings. When grown in rich medium, greater than
50% of the minCD mutant cells had multiple FtsZ rings,
indicating significant differences in regulation of FtsZ ring formation
based on growth medium.
