[Properties of bacteria of pathovars of Pseudomonas syringae affecting cereals].
Antigenic properties of Pseudomonas syringae pv. coronafaciens isolated from the oats have been studied for the first time, and serologic grouping of the strains of P. syringae pv. coronafaciens and P. syringae pv. atrofaciens has been carried out. It has been determined that the strains of P. syringae pv. coronafaciens, as to availability of specific antigenic complexes belong to two serological groups I and V, and thus they are differed from the strains of the pathovar atrofaciens which includes four serological groups of the strain isolated from wheat (II, IV, V, VI) and five serological groups of the strains, isolated from rye (I, II, IV, V, VI). It has been shown that the overwhelming majority of strains of P. syringae pv. coronafaciens isolated from the affected plants of the oats belong to serogroup V, while P. syringae pv. atrofaciens from the rye--to serogroup I. The strains of these bacteria, isolated as epiphytes, dominate in the other serological groups.
