Analysis of ABR in Tn21 Relatives. (A) TnCentral sequence search using the sequence of Tn5060, the proposed ancestor of Tn21, as a query. The query entry box and the customizable BLAST parameters are shown. The display of the parameters can be hidden/shown by clicking on the red double arrowhead. (B) Sequence search results. The query sequence is represented by the width of the alignment column. The red bars represent regions of the matched transposons that are highly similar to regions of Tn5060. (C) ABR genes and targeted antibiotic classes in Tn21 relatives. Red shading in the table cells indicates that the transposon carries at least one gene targeting the antibiotic class; blue shading indicates that it does not. The ABR genes found in each transposon are indicated in the table cells.
