a
Hard, genes present in 100% of the genomes; soft, genes present in 95% of the genomes.
b
Analyses of pv. nerii and pv. savastanoi considering the oleander strains 0485_9 and ICMP 13786 as belonging to pv. nerii, as they were originally classified. The other analyses were done including these two strains in pv. savastanoi, as indicated by the cross-pathogenicity tests.
