Bootscanning analysis of the 3′ terminal 7.2-kb of the genomes of Australian IBVs. The y-axis shows the percentage of permutated trees using a sliding window of 200 bp wide centered on the position plotted, with a step size between plots of 20 bp. IBV strains VicS and N1/88 were compared to N1/03, with Armidale used as the query strain. The genomic map is shown at the top of the plot. The vertical lines are the breakpoints and the numbers at the bottom of these lines are their positions in the sequence
