''Carmotetraviridae'' is a family of
positive-strand RNA viruses. There is only one genus in this family, ''Alphacarmotetravirus'', which has one species: Providence virus (''Alphacarmotetravirus providencense'').
Lepidopteran insects serve as natural hosts.
Structure
Viruses in ''Carmotetraviridae'' are
non-enveloped, with
icosahedral geometries, and
T = 4 symmetry. The virion diameter is around 40 nm.
Genome
Genomes are linear, around 6.1kb in length. The genome codes for two proteins, and has three
open reading frames.
Life cycle
Viral replication is
cytoplasm
The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell a ...
ic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the
positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by suppression of termination. Lepidopteran insects serve as the natural
host. Transmission routes are oral and tissue tropism is the midgut.
