Figure 1From: Phylogenetic detection of horizontal gene transfer during the step-wise genesis of Mycobacterium tuberculosisPhylogeny of Mycobacterium genus and schematic representation of acquisition of foreign genes at different strata of M. tuberculosis evolution. The radial tree was generated using MEGA 4.1. The different mycobacterial lineages, based on slow-growing versus rapid-growing organisms, are also indicated. The arrow indicates schematically the positions of the different list of HGT, detected in this study (A, B, C and D), during the step-wise evolution of slow-growing mycobacteria. The scale represents the number of amino acid differences.Back to article page
