Name, Synonyms and Lineage

ICTV approved acronym: GV. Virus is of the family 00.006. Baculoviridae.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. During their life cycle, virions can occur in two phenotypes. The infection is initiated by extracellular virions in the gut epithelium (phenotype I) and phenotype II virions generated when the nucleocapsids bud through the plasma membrane at the surface of infected cells (termed budded virions or BV). Virus may be sequestered within inclusion bodies that are occluded by a crystalline protein matrix composed of a single viral protein, granulin. Virus initiating infection is occluded by a crystalline protein matrix of ovicylindrical shape. Each occlusion body measures 0.13-0.5 μm and contains one virion; virions in occlusions consist of a single nucleocapsid (S). Virus capsid is enveloped. Virions are rod-shaped. Virions measure 120-300 nm in diameter; 300-500 nm in length. Intracellular virions are enveloped. The envelope surrounds usually one nucleocapsid (although occasionally multiple nucleocapsids found). Capsid/nucleocapsid is elongated with helical symmetry. The nucleocapsid is rod-shaped with a length with a length of 250-300 nm and a width of 30-60 nm.

Nucleic Acid

The genome is not segmented and contains a single molecule of circular, supercoiled, double-stranded DNA. The complete genome is 100000-180000 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 125600 nucleotides long.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins located in the envelope and capsid (only BV), envelope, capsid, and occlusion bodies (ODV).

Structural Proteins: Envelope protein occlusion protein polyhedrin; has a molecular mass of 25000-33000 Da.

Lipids

Lipids are present and located in the envelope (of ODV and BV).
