Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella. ... Diseases caused by P. syringae tend to be favoured by wet, cool conditions ...
This bacterium also causes disease in snap bean (Phaseolus vulgaris) and lima bean (Phaseolus lunatus), however it is more commonly seen in soybean. [4] Pseudomonas syringae pv. glycinea attacks all of the above-ground parts of soybean, but symptoms are typically seen on the mid-upper canopy of leaves and pods. [5]
In the past few years, the bacterial pathogen Pseudomonas syringae pv. aesculi has emerged as a new and virulent agent for this disease in Western Europe. Specific to horse chestnut trees, this pathogen infects the bark around the trunk and main branches. As it spreads, it cuts off the water supply to the crown; and when it completely encircles ...
Halo blight of bean is a bacterial disease caused by Pseudomonas syringae pv. phaseolicola. Halo blight’s pathogen is a gram-negative, aerobic, polar-flagellated and non-spore forming bacteria. This bacterial disease was first discovered in the early 1920s, and rapidly became the major disease of beans throughout the world.

Notably, the Pseudomonas syringae family is linked to diseases affecting a wide range of agricultural plants, with different strains showing adaptations to specific host species. In particular, the virulent strain Pseudomonas tolaasii is responsible for causing blight and degradation in edible mushroom species. [47]
