Dinodnavirus

From WikiMD.com - Food, Medicine & Wellness Encyclopedia

Dinodnavirus is a genus of viruses in the family Parvoviridae. Dinodnaviruses are known to infect dinoflagellates, a group of single-celled organisms found in marine and freshwater environments. The name "Dinodnavirus" is derived from "dinoflagellate DNA virus".

Taxonomy[edit | edit source]

The genus Dinodnavirus is part of the subfamily Densovirinae, within the family Parvoviridae. The Parvoviridae family is composed of small, non-enveloped viruses with a linear, single-stranded DNA genome. The family is divided into two subfamilies: the Densovirinae, which infect invertebrates, and the Parvovirinae, which infect vertebrates.

Structure[edit | edit source]

Dinodnaviruses are non-enveloped viruses with icosahedral symmetry. The capsid is composed of 60 capsomers and is approximately 18-26 nm in diameter. The genome is linear, non-segmented, and around 4-6 kilobases in length.

Life Cycle[edit | edit source]

The life cycle of Dinodnavirus involves attachment to the host cell, penetration into the cell, uncoating of the virus, replication of the viral genome, assembly of new virus particles, and release of the new viruses from the host cell. The virus attaches to the host cell using a viral attachment protein, which binds to a receptor on the host cell surface. The virus then enters the cell through receptor-mediated endocytosis.

Pathogenicity[edit | edit source]

Dinodnaviruses are known to cause disease in dinoflagellates, leading to population declines in some species. The impact of these viruses on dinoflagellate populations can have significant effects on marine and freshwater ecosystems, as dinoflagellates play a crucial role in these environments.
