Polyphasic study of phytopathogenic bacterial strains associated with deep bark canker of walnut in Serbia revealed a new species, sp. nov.

Serious outbreaks of walnut deep bark canker were observed on young walnut trees ( L.) in two localities in the northern part of Serbia during 2020. From the symptomatic walnut tissues, two types of bacterial colonies were isolated, predominantly, light cream, circular and smooth colonies, as well as small, yellowish, mucoid and convex ones.

Characterization of Strains Associated with Shoot Blight of Raspberry and Blackberry in Serbia.

During May 2016, severe blight symptoms were observed in several raspberry and blackberry fields in Serbia. In total, 22 strains were isolated: 16 from symptomatic raspberry shoots, 2 from asymptomatic raspberry leaves, and 4 from symptomatic blackberry shoots. Additionally, eight raspberry strains, isolated earlier from two similar outbreaks, were included in the study.

Selective Quantification of Erwinia amylovora Live Cells in Pome Fruit Tree Cankers by Viability Digital PCR.

The accurate assessment of Erwinia amylovora live cell populations in fire blight cankers by classic microbiology methods has major limitations. Some of them are the presence of competitive microbiota in samples that inhibit E. amylovora's growth and the release of toxic compounds by plant material during sample processing, which may hamper the pathogen's ability to form colonies on solid media.

Isolation, Characterization and Draft Genome Analysis of Bacteriophages Infecting .

Bacterial fruit blotch and seedling blight, caused by , is one of the most destructive diseases of melon and watermelon in many countries. Pathogen-free seed and cultural practices are major pillars of the disease control. However, use of bacteriophages as natural biocontrol agents might also contribute to the disease management.

Bacteriophage-Mediated Control of Phytopathogenic Xanthomonads: A Promising Green Solution for the Future.

Xanthomonads, members of the family , are economically important plant pathogenic bacteria responsible for infections of over 400 plant species. Bacteriophage-based biopesticides can provide an environmentally friendly, effective solution to control these bacteria. Bacteriophage-based biocontrol has important advantages over chemical pesticides, and treatment with these biopesticides is a minor intervention into the microflora.

New Postharvest Fungal Pathogen in Serbia.

is one of the important species of genus , which has cosmopolitan distribution and is encountered on a wide range of different habitats. This species has not been considered as an important plant pathogen, even though it has been isolated from various plant hosts. Fruits and vegetables with -like mold symptoms were collected from 2015 to 2017 from markets in Serbia.

Complete Genome of the Specific Bacteriophage KΦ1, Its Survival and Potential in Control of Pepper Bacterial Spot.

phage KΦ1, a member of family, was isolated from the rhizosphere of pepper plants showing symptoms of bacterial spot. The phage strain expressed antibacterial activity to all strains tested and did not lyse other spp., nor other less related bacterial species.

Draft Genome Sequences of Agrobacterium nepotum Strain 39/7T and Agrobacterium sp. Strain KFB 330.

Tumorigenic strains of Agrobacterium spp. are responsible for crown gall disease of numerous plant species. We present here draft genome sequences of nonpathogenic Agrobacterium nepotum strain 39/7(T) (CFBP 7436(T), LMG 26435(T)), isolated from crown gall tumor on Prunus cerasifera, and tumorigenic Agrobacterium sp.
