Pseudomonas viridiflava is a fluorescent, Gram-negative, soil bacterium that is pathogenic to plants. It was originally isolated from the dwarf or runner bean, in Switzerland. Based on 16S rRNA analysis, P. viridiflava has been placed in the P. syringae group. Following ribotypical analysis misidentified strains of Pseudomonas syringae pv. ribicola (which infects Ribes aureum) and Pseudomonas syringae pv. primulae (which infects Primula species) were incorporated into this species. This pathogen causes bacterial blight of Kiwifruit.
