Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella.As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, [2] all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.
Pseudomonas syringae pv. Aesculi is a bacterium that causes bleeding canker of horse chestnut. The pathogen overwinters in the soil and can survive in the soil for about a year. [2] It is spread by water, rain, and tools that were used on the infected tree. [3] It causes lesions on the bark of the tree that can be near the base of the trunk or ...
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
Pseudomonas andropogonis. Chocolate spot: Pseudomonas syringae pv. coronafaciens. Goss's bacterial wilt and blight (leaf freckles and wilt) [1] Clavibacter michiganensis subsp. nebraskensis [2] = Corynebacterium michiganense pv. nebraskense. Holcus spot: Pseudomonas syringae pv. syringae van Hall. Purple leaf sheath: Hemiparasitic bacteria ...
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]
Halo Blight is an important disease to beans, a money crop, which allow the pathogen Pseudomonas syringae to continue its lifespan. Beans are only one cash crop that can be affected by halo blight. Fields that are affected by this bacteria are at risk for the spread of it by way of rain, wind, or organisms but a widespread infection isn’t ...
P. syringae is a prolific plant pathogen. It exists as over 50 different pathovars, many of which demonstrate a high degree of host-plant specificity. Numerous other Pseudomonas species can act as plant pathogens, notably all of the other members of the P. syringae subgroup, but P. syringae is the most widespread and best-studied. [citation needed]
The most common cause of bacterial leaf spots are by bacteria in the genera Pseudomonas and Xanthomonas. For example, Pseudomonas syringae pv. tabaci is known to cause angular leaf spots of cucumber, Pseudomonas syringae pv. phaseolicola to cause bean leaf spot and Xanthomonas campestris pv. phaseoli, angular leaf spot of cotton.
