From the concatenated ubiquitous gene alignment (numbers indicate nonparametric bootstrap results in percentage out of 1,000 experiments); from the concatenated 1,000 nucleotides regions (± 500 nucleotides) surrounding ubiquitous DNA uptake sequence (DUS) sites in the M-GCAT multiple alignment; and entire concatenated M-GCAT multiple alignment. Distance matrices were computed from the alignments using Tree-Puzzle [85] by maximum likelihood with the HKY+Γ model and trees computed with BIONJ [86].Copyright information:Taken from "The impact of the neisserial DNA uptake sequences on genome evolution and stability"http://genomebiology.com/2008/9/3/R60Genome Biology 2008;9(3):R60-R60.Published online 26 Mar 2008PMCID:PMC2397512.
