Group designation and original plant source are given, with GenBank accession numbers for sequences used in phylogenetic tree construction (Borschinger et al., 2016).
∧Pathogenicity designations taken from significant log rank post hoc pairwise comparisons of survival data. In aphids, there is one overlap between the highest ‘Low’ strain and the lowest ‘Medium’ strain (pv. japonica and pv. aptata were not significantly different). In whiteflies, pv. syringae overlaps with pv. aceris and pv. phaseolicola.
‡Pathovar is renamed as Pseudomonas savastanoi, not P. syringae.
¥Strain is renamed as Pseudomonas cannabina pv. asilensis.
♢JGI project id, not GenBank accession.
