Consensus tree based on tmRNA sequences determined in this study. For details on the Lactococcus lactis group see Table 2. The sequence of E. coli was used for setting the root. The bar represents 10% estimated sequence divergence. *Sequences of bacteria presented without a strain number were taken from the tmRNA databases (references 16, 17).
