Horizontal gene transfer of UlaGL genes to halophilic Archea. A. Alignment of UlaGL sequences from halophilic archea, along with two reference sequences (E. coli UlaG, and the halophilic bacterium Acetohalobium arabaticum). B. Bayesian consensus tree of the same sequences in A, with E. coli UlaG as the outgroup. Bayesian inference posterior probability (BIPP) and maximum-likelihood bootstrap percentage (MLBP) are indicated on nodes. Only branches with > 0.50 BIPP support are labeled with BIPP and MLBP. The SDSF at the end of the MrBayes run was 0.007. The scale bar below the tree shows the evolutionary distance expressed as substitutions per site. Taxon names are prefixed with their NCBI GI numbers. Nexus alignment file is available from the authors on request.
