dc.description.abstract | Commercial production of the ornamental plant dipladenia (Mandevilla spp.) is threatened by dipladenia leaf and stem spot disease, caused by the bacterium Pseudomonas savastanoi. P. savastanoi includes four pathovars of woody hosts differentiated by a characteristic host range in olive, oleander, ash and broom plants. However, isolates from dipladenia have not been ascribed to any particular lineage or P. savastanoi pathovar. Here we report that isolates from dipladenia represent a distinct, clonal lineage. First, dipladenia isolates display very similar plasmid profiles, including a plasmid encoding the iaaM gene for biosynthesis of indole-3-acetic acid. Second, multilocus sequence analysis and core-genome single-nucleotide-polymorphisms phylogenies showed a monophyletic origin for dipladenia isolates, which cluster with isolates from oleander (pathovar nerii) in a distinct clade well separated from other P. savastanoi strains. Metabolic profiling and cross-pathogenicity tests in olive, oleander, ash, broom and dipladenia clearly distinguished dipladenia isolates from the four P. savastanoi pathovars. Comparative genomics of the draft genome sequence of the dipladenia strain Ph3 with the other four pathovars showed that Ph3 encodes very few strain-specific genes, and a similar set of virulence genes to pv. nerii, including its repertoire of type III secretion system effectors. However, hierarchical clustering based on the catalogue of effectors and their allelic variants clearly separated Ph3 from pv. nerii strains. Based on their distinctive pathogenicity profile, we propose a de novo pathovar for P. savastanoi isolates from dipladenia, P. savastanoi pv. mandevillae pv. nov., for which strain Ph3 (CFBP 8832PT) has been designated as the pathotype strain. | en |
