Comparative genomic and phylogenetic approaches to characterize the role of genetic recombination in mycobacterial evolution.

Specifically, whereas events 27 and 39 yielded only marginally significant evidence that the tree topologies obtained using the recombinant fragments fitted the data significantly better than the tree topology determined from the 720,090 nt long original alignment ( i.e., yielded test p-values between 0.05 and 0.01), events 7 and 10 only yielded statistically significant p-values for the AU test, events 8, 13, 16, 28, 33, 34, and 74 only yielded significant p-values for the AU and WSH tests and none of these yielded significant p-values with the SH test.
