Chaetoceros salsugineum DNA virus 01
Bacilladnavirus is a genus of single stranded DNA viruses. Species in this genus infect diatoms. The name is derived from the phrase: ssDNA virus infecting Bacillariophytes. Although other single-stranded DNA viruses which infect diatoms have been discovered (Chaetoceros debilis DNA virus (CdebDNAV), C. tenuissimus DNA virus (CtenDNAV), C. lorenzianus DNA virus (ClorDNAV), C. sp. strain TG07-C28 DNA virus (Csp05DNAV), C. setoensis DNA virus (CsetDNAV), and Thalassionema nitzschioides DNA virus (TnitDNAV)), the only species officially classified in this genus is Chaetoceros salsugineum DNA virus 01 (CsalDNAV01.) It was suggested that the family Bacillariodnaviridae be used to classify these viruses, but this classification has not been officially accepted.
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.
These viruses have been isolated from diatoms of the Chaetoceros genus.
The virions are ~34 nanometers (nm) in diameter.
The virions accumulate in the nucleus.
Mature virions are released by lysis of the host.
