ComM is required for integration of DNA during natural transformation. (A) Chitin-dependent natural transformation assays in the indicated strains using a linear PCR product or a replicating plasmid as tDNA. (B) Chitin-independent transformation assays of the indicated strains with linear PCR product as tDNA. (C) Complementation of comM in trans tested in chitin-dependent transformation assays using a linear PCR product as tDNA. All data are shown as the mean ± SD and are the result of at least three independent biological replicates. **P < 0.01, ***P < 0.001, NS = not significant.
