Genus

Bacillariodnavirus

Bacillariodnaviridae is a family of single straned DNA viruses that infect diatoms.[1] The family has only a single genus at present - Bacillariodnavirus

Description[edit]

The genome of these viruses appears to be unique. It consists of a single molecule of covalently closed circular single stranded DNA of ~6 kilobases as well as a segment of linear ssDNA of ~1 kilobase. The linear segment is complementary to a portion of the closed circle creating a partially double stranded region.

There are at least three major open reading frames: one of these has a high similarity to replicase related proteins of the other ssDNA viruses.

Taxonomy[edit]

There is only one genus in this family at present.
