FIGURE 1.

A phylogenetic tree showing all 12 strains used in the study, alongside their virulence to both whiteflies and aphids. White boxes denote where data is not available for those strains. Separate keys indicate virulence to each insect as percentage dead at 72 h post-infection. The phylogenetic tree was constructed in PhyloPhlAn (Segata et al., 2013) using 399 of the most conserved protein sequences across the genomes of the 12 strains, encompassing 1969 informative sites. Protein sequences were obtained from GenBank (see Table 1).
