Biological control of important fungal diseases of potato and raspberry by two strains.

Stem canker and black scurf caused by are the important diseases in potato, while spur blight caused by is a major disease in red raspberry. In Western Siberia, both crops are grown predominantly in small-scale farming that requires maximal usage of biological products for plant protection instead of chemicals. We evaluated two promising strains BZR 336 g and BZR 517 isolated in the south of Russia (45°1'N, 38°59'E) for their biological control potentials against the potato and red raspberry diseases under the more severe weather conditions of Western Siberia (55°1'N, 82°55' E).

Draft Genome Sequence of Bacillus velezensis BZR 277, a Prospective Biocontrol Agent against Phytoparasitic Nematodes.

strain BZR 277 is a rhizobacterium isolated from the rhizoplane of a winter oilseed rape plant from the Krasnodar region in Russia. This study presents the genome sequence of the rhizobacterium BZR 277, which exhibited high antagonistic activity against the root-knot nematode Kof. The data on the genome sequence can help to identify pathways for the biosynthesis of metabolites responsible for nematicidal activity in order to improve crop protection against plant-parasitic nematodes.

Draft Genome Sequence of the Plant Growth-Promoting Bacterium Bacillus subtilis Strain BZR 517, Isolated from Winter Wheat, Now Reclassified as Bacillus velezensis Strain BZR 517.

strain BZR 517 is a prospective plant growth-promoting rhizobacterium with known biocontrol properties, which may be used to improve soil quality. The genome sequencing was conducted as part of new biological agent development in order to determine the biocontrol potential of the strain, including the production of biologically active compounds.

Draft Genome Sequence of Bacillus velezensis BZR 336g, a Plant Growth-Promoting Antifungal Biocontrol Agent Isolated from Winter Wheat.

strain BZR 336g is a plant growth-promoting rhizobacterium isolated from a winter wheat rhizoplane from the Krasnodar region in Russia. In this study, we report the genome, including genes with known phenotypic function, i.e.

Optimization of laboratory cultivation conditions for the synthesis of antifungal metabolites by bacillus subtilis strains.

In order to achieve the optimal number of colony forming units and a high level of antifungal metabolites synthesis, we carried out the periodic cultivation of the BZR 336 g and BZR 517 strains at various pH and temperature levels. In the experiment for determining the optimal temperature, the maximum titer of BZR 336 g bacterium (1.6-1.

Adaptation of primocane fruiting raspberry plants to environmental factors under the influence of Bacillus strains in Western Siberia.

In geographical locations with a short vegetative season and continental climate that include Western Siberia, growing primocane fruiting raspberry varieties becomes very important. However, it is necessary to help the plants to overcome the environmental stress factors. This study aimed to evaluate the impact of the pre-planting treatment of primocane fruiting raspberry root system with Bacillus strains on the following plant development under variable environmental conditions.

Possibility of biological control of primocane fruiting raspberry disease caused by Fusarium sambucinum.

Biological control agents are a promising alternative to chemical pesticides for plant disease suppression. The main advantage of the natural biocontrol agents, such as antagonistic bacteria compared with chemicals, includes environmental pollution prevention and a decrease of chemical residues in fruits. This study is aimed to evaluate the impact of three Bacillus strains on disease of primocane fruiting raspberry canes caused by Fusarium sambucinum under controlled infection load and uncontrolled environmental factors.
