Bacteriophage genomes can be highly mosaic, i.e. the genome of many phage species appear to be composed of numerous individual modules. These modules may be found in other phage species in different arrangements. Mycobacteriophages, bacteriophages with mycobacterial hosts, have provided
Some phages have been found to be immune to this mechanism as well. In some way or another, the phages have managed to get rid of the sequence that would be replicated. A third way that bacteria have managed to escape the effects of bacteriophages is by abortive infection. This is a last resort option- when the host cell has already been ...
Plant pathogens, organisms that cause infectious plant diseases, include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. [2] In most plant pathosystems, virulence depends on hydrolases and enzymes that degrade the cell wall.
The bacterial phytopathogen Rhodococcus fascians has been demonstrated as one cause of fasciation, such as in sweet pea (Lathyrus odoratus) plants, [7] and in lilies (Lilium longiflorum), [8] but many fasciated plants have tested negative for the bacteria in studies, [9] [better source needed] hence bacterial infection is not an exclusive ...
[9] [10] Currently, the suggested procedure of naming strains is as follows: Cyanophage Xx-YYZaa, where Xx is the first two letters of the genus and species names of the host that the type specimen phage is found in, YY is the origin of the specimen, Z is the virus family, and aa is the reference number of the virus.

In plant immunology, the hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
Transmission electron micrograph of multiple bacteriophages attached to a bacterial cell wall. A phageome is a community of bacteriophages and their metagenomes localized in a particular environment, similar to a microbiome. [1] [2] Phageome is a subcategory of virome, which is all of the viruses that are associated with a host or environment. [3]
A Bacillus phage is a member of a group of bacteriophages known to have bacteria in the genus Bacillus as host species. These bacteriophages have been found to belong to the families Myoviridae, Siphoviridae, Podoviridae, or Tectiviridae.
