Dot matrix view of the BLAST results showing regions of similarity of the five isolates. The query sequence is represented on the X-axis and the numbers represent the bases/residues of the query. The subjects are represented on the Y-axis and again the numbers represent the bases/residues of the subject. Alignments are shown in the plot as lines. Minus strand matches are slanted from the upper left to the lower right. The number of lines (n = 1) shown in the plot is the same as the number of alignments (n = 1) found by BLAST. Query coverage was 96% and maximum identity was 99%.
