Phytopathogenic Strains Circulating on Leguminous Plants, Alternative Hosts and Weeds in Russia.

Many bacterial plant pathogens have a broad host range important for their life cycle. Alternate hosts from plant families other than the main (primary) host support the survival and dissemination of the pathogen population even in absence of main host plants. Metabolic peculiarities of main and alternative host plants can affect genetic diversity within and between the pathogen populations isolated from those plants.

Bacteriophage Possum: A Complex Polysaccharide-Deacetylating Tail Fiber as a Tool for Host Recognition in Pectobacterial .

Novel, closely related phages Possum and Horatius infect , a phytopathogen causing soft rot in potatoes and other essential plants. Their properties and genomic composition define them as N4-like bacteriophages of the genus , a part of a recently formed family . It is proposed that the adsorption apparatus of these phages consists of tail fibers connected to the virion through an adapter protein.

Ayka, a Novel Bacteriophage, Provides Protection against Soybean Bacterial Wilt and Tan Spot.

Diseases caused by the Gram-positive bacterium pv. (Cff) inflict substantial economic losses in soybean cultivation. Use of specific bacterial viruses (bacteriophages) for treatment of seeds and plants to prevent the development of bacterial infections is a promising approach for bioprotection in agriculture.

Bacteriophage Arno 160 Infects via Depolymerization of the Bacterial O-Polysaccharide.

Phytopathogenic bacteria belonging to the and genera (soft-rot ) are in the focus of agriculture-related microbiology because of their diversity, their substantial negative impact on the production of potatoes and vegetables, and the prospects of bacteriophage applications for disease control. Because of numerous amendments in the taxonomy of , there are still a few studied sequenced strains among this species. The present work reports on the isolation and characterization of the phage infectious to the type strain of .
