All isolates of “P. savastanoi” were recently classified by Dye et al. (Plant Pathol. 59:153-168,1980) as members of a single pathovar of P. syringae van Hall. It appears, however, that these isolates differ sufficiently from the other members of P. syringae to justify subspecies rank for them. The following classification and nomenclature are therefore proposed: Pseudomonas syringae subsp. savastanoi (ex Smith) subsp. nov., nom. rev., to include the olive pathogen (pathovar oleae), the ash pathogen (pathovar fraxini), and the oleander pathogen (pathovar nerii). The type strain of P. syringae subsp. savastanoi is ATCC 13522 (= NCPPB 639). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-32-2-166
