title: Insights into the genetic organization of the Bacillus mycoides cryptic plasmids pDx14.2 and pSin9.7 deduced from their complete nucleotide sequence.
abstract: Bacillus mycoides, a member of the Bacillus cereus group of bacteria, can be easily distinguished from close species because of colony shape, made by filaments of cells, resembling fungal hyphae, curving clock- or counterclockwise depending on the strain. Two plasmids, one from a strain curving to the right (pDx14.2), the other from a strain curving to the left (pSin9.7), were sequenced and analyzed for gene content and replication mode. Rolling-circle replication modules and mobilization proteins were found, very similar to those of other plasmids of the B. cereus group bacilli, mostly Bacillus thuringiensis living in the same ecosystem, suggesting active plasmid exchange in nature.
