Summary
Researchers sequenced the Bacillus subtilis phage ϕ105 genome, revealing 52 coding sequences. The phage DNA disrupts the radC gene, which is involved in bacterial competence regulation.
Area of Science:
- Microbiology
- Genomics
- Molecular Biology
Background:
- Bacillus subtilis is a model organism for microbial research.
- Temperate phages are viruses that can integrate into the host genome.
- The radC locus is part of the ComK regulon, essential for competence development.
Purpose of the Study:
- To determine the complete genome sequence of the Bacillus subtilis temperate phage ϕ105.
- To investigate the integration site of the ϕ105 prophage in the B. subtilis genome.
Main Methods:
- Whole-genome sequencing of Bacillus subtilis temperate phage ϕ105.
- Bioinformatic analysis of the genome sequence.
- Characterization of the prophage integration site in a lysogenic B. subtilis strain.
Main Results:
- The complete genome sequence of phage ϕ105 is 39,318 bp and contains 52 coding sequences.
- The ϕ105 prophage integrates into the radC locus of the B. subtilis genome.
- The radC locus is confirmed to be part of the competence-induced ComK regulon.
Conclusions:
- The genome sequence provides a foundation for further studies on ϕ105 biology and evolution.
- The integration of ϕ105 into the radC locus may impact bacterial competence and phage-host interactions.
- This study enhances our understanding of phage-host dynamics in Bacillus subtilis.

DNA Bacteriophages
Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...
Lytic Cycle of Bacteriophages
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the lytic replication...
Lysogenic Cycle of Bacteriophages
In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...
Viral Replication: Lytic Cycle
Bacteriophages, or phages, are viruses that specifically infect bacteria. Among them, T-even bacteriophages, such as T4, exhibit a well-characterized lytic replication cycle in Escherichia coli (E. coli). This process ensures the rapid proliferation of the virus while ultimately leading to the destruction of the bacterial host.Attachment and DNA InjectionThe infection process begins with the recognition and binding of the T4 phage to the E. coli cell surface. Tail fibers of the phage...
Bacterial Phylum Tenericutes
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...
Bacterial Phylum Verrucomicrobiota
The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...
