Fig. 6. Molecular dating of blaNDM mobilization by Tn125 and Tn3000.
Posterior density distributions of ancestral sequence age (i.e., root height) for the Tn125 (a) and Tn3000 (b) transposons. The ancestral sequence emergence was estimated using two Bayesian tip-dating approaches implemented in BactDating and BEAST2. Three different population growth priors were used in case of BEAST2: Coalescent Constant Population, Coalescent Exponential Population, and Coalescent Bayesian Skyline as given by the colour scheme and legend at right. Median estimates with 95% highest density interval (HDI) are provided in the panel legends.
