Figure 1. Barcode gaps for candidate targets.

Barcode gap analysis of potential barcodes derived from the 16S rRNA and cpn60 genes. Each panel shows the distribution of inter- (red) and intra-specific (green) distances in terms of percent of the total number of comparisons made (see Table 2). In cases where percent values exceed 20, the actual value is indicated above an arrow on the relevant bar in the chart. For both V6-alternate and cpn60 UT, only distances up to 1.00 are plotted.
