Characterization of mint virus C, a new member of the genus Carlavirus.

Here, we report the complete genome sequence of a new carlavirus causing mosaic on mint plants in Italy, which we have tentatively named "mint virus C" (MVC). Flexuous particles of around 600 nm were observed using transmission electron microscopy, and next-generation sequencing was performed to determine the nucleotide sequence of the MVC genome, which was found to be 8558 nt long, excluding the poly(A) tail, and shows the typical organization of a carlavirus. The putative proteins encoded by MVC are 44-56% identical to the closest matches in the NCBI database, suggesting that MVC should be considered a member of a new species in the genus Carlavirus.

Evolution of a novel engineered tripartite viral genome of a torradovirus.

Viruses in the include monopartite and bipartite genomes, suggesting the possibility to study members of this family to experimentally address evolutionary transitions resulting in multipartitism. Torradoviruses are bipartite members of the family characterized by a genus-specific 5' open reading frame, named P21, encoded by RNA2. Here, in a study originally intended to verify if P21 can function , we attempted to provide P21 from a third P21-expressing construct under control of the 35S promoter and containing the 5'- and 3'-untranslated regions (UTRs) of wild-type (WT) RNA2.

Natterin-like and legumain insect gut proteins promote the multiplication of a vector-borne bacterial plant pathogen.

Phytoplasmas are phloem-limited plant pathogenic bacteria causing diseases in many plant species. They are transmitted by Hemipteran insect species in a persistent-propagative manner. Phytoplasmas are wall-less, and their membrane proteins are involved in pathogen internalization into host cells.

Isolation, characterization and genome analysis of the orphan phage Kintu infecting Xanthomonas vasicola pv. musacearum.

Background: Xanthomonas vasicola pv. musacearum is responsible for the widespread Banana Xanthomonas Wilt in banana cultivation regions across the globe. Biocontrol measures for disease management remain limited amidst increasing antimicrobial resistance and unsustainable conventional agricultural practices.

Characterization of four phages and their potential in phage biocontrol for lamb's lettuce seed decontamination.

Bacterial black spot, caused by , is responsible for significant yield losses in lamb's lettuce () in many producing countries, especially Europe. Currently, no resistant varieties of are available that effectively control the disease under field conditions. Bacteriophage-based biocontrol has been suggested as a sustainable and natural alternative strategy to combat bacterial pathogens.
