Family:	Yueviridae

Yueviridae is a family of bacteriophages, which are viruses that infect bacteria. This family is part of the order Crassvirales, within the class Caudoviricetes. Members of the Yueviridae family are characterized by their double-stranded DNA genomes and their ability to infect specific bacterial hosts.

Taxonomy

The family Yueviridae is classified under the order Crassvirales, which is known for containing bacteriophages with long, non-contractile tails. The taxonomy of Yueviridae is based on genomic and morphological characteristics, as well as the specific bacterial hosts they infect.

Genera

The family Yueviridae includes several genera, each containing multiple species. The classification into genera is based on genetic similarities and differences, as well as host range.

Morphology

Viruses in the Yueviridae family typically have an icosahedral capsid and a long, non-contractile tail. The capsid is composed of protein subunits that protect the viral DNA. The tail is used to attach to the bacterial host and inject the viral genome into the host cell.

Genome

The genome of Yueviridae viruses is composed of double-stranded DNA. The size of the genome can vary between different genera and species within the family. The genome encodes for proteins necessary for the replication of the virus, as well as structural proteins that make up the capsid and tail.

Life Cycle

The life cycle of Yueviridae bacteriophages involves several key steps:

1. Attachment: The phage attaches to the surface of a susceptible bacterial cell using its tail fibers.
2. Penetration: The phage injects its DNA into the host cell, leaving the capsid outside.
3. Replication: The viral DNA is replicated using the host's cellular machinery.
4. Assembly: New viral particles are assembled within the host cell.
5. Lysis: The host cell is lysed, releasing new phage particles to infect other bacteria.

Ecological Role

Yueviridae bacteriophages play a significant role in regulating bacterial populations in various environments. They contribute to the horizontal gene transfer among bacteria and can influence bacterial evolution.

Research and Applications

Research on Yueviridae and other bacteriophages is important for understanding bacterial ecology and evolution. Bacteriophages are also being explored as potential tools in phage therapy, which involves using phages to treat bacterial infections, especially those resistant to antibiotics.
