[Phenotypical and genotypical characteristics of the pathogen in lupine bacterial brown spottiness].

It has been determined with the help of analyzing the complex of phenotypical and genotypical properties, that Pseudomonas lupini is not a separate species. It has been shown that lupin's bacterial spot is induced by phytopathogenic bacteria of two species P. syringae and P. savastanoi. On the basis of their high phenotypical and genotypical similarity with a typical strain Pseudomonas syringae pv. syringae B1027 the majority of investigated strains are related to P. syringae. The only exception was the strain 8531, which was referred to Pseudomonas savastanoi pv. glycinea on the basis of its antigenic and genotypical properties.
