What is Pseudomonas syringae pv actinidiae?

What is Pseudomonas syringae pv actinidiae?

Pseudomonas syringae pv. actinidiae (Psa) is a gram-negative bacterium that infects several Actinidia species, being responsible for the kiwifruit bacterial canker (KBC) (Vanneste et al., 2014; Kisaki et al., 2018). Following the first outbreaks of Psa in A. chinensis var.

What is Pseudomonas syringae pv Lachrymans?

Angular leaf spot, caused by Pseudomonas syringae pv. lachrymans, affects all species of cucurbits and is one of the most serious diseases of cucumber. The pathogen overwinters primarily on contaminated seed, where bacterial cells survive under the seed coat. During germination, primary infections appear.

Where do you find Pseudomonas syringae?

Pseudomonas syringae is one of the most common plant pathogens that infect the phyllosphere. P. syringae can live on the plant surface as an epiphyte. To cause disease, it enters the plant, through wounds or natural openings such as stomata, and multiplies within the apoplast.

Is Pseudomonas syringae gram positive?

Pseudomonas syringae is a Gram-negative, aerobic, rod-shaped bacteria. One distinguishing characteristic is its polar flagella.

What kills Pseudomonas syringae?

The most common strategy for controlling diseases caused by Pseudomonas syringae is, as it has been for more than 5 decades, to spray bactericides. These mainly include a variety of copper compounds or other heavy metals, with or without various combinations of fungicides or other pest-control chemicals.

Is Pseudomonas syringae harmful to humans?

Based on extensive testing and the methods used in applying the bacteria to the fruit, these bacterial strains are not expected to harm either humans or the environment when used in pesticide products.

What is Pseudomonas syringae pv syringae?

Abstract. Pseudomonas syringae is one of the best studied plant pathogens and it serves as a model for understanding host-microbe interactions, bacterial virulence mechanisms, host adaptation of pathogens, as well as microbial evolution, ecology and epidemiology.

What kind of bacteria is Pseudomonas syringae?

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, all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.

How does Pseudomonas syringae work?

Pseudomonas syringae produces highly efficient biological ice nuclei (IN) that were proposed to influence precipitation by freezing water in clouds. This bacterium may be capable of dispersing through the atmosphere, having been reported in rain, snow, and cloud water samples.

What disease does Pseudomonas syringae cause?

The organism Pseudomonas syringae causes a disease known as “bacterial canker” on almond trees.

How is Pseudomonas syringae treated?

What is Pseudomonas syringae common name?

bacterial canker or blast
