Rhizidiovirus
Encyclopedia
The Rhizidiovirus genus consists of dsDNA virus

The genome is non segmented, linear double stranded DNA and ~25.5 kilobases in length. It has a guanine
+ cytosine
content of 42%. It encodes at least 14 protein with molecular weights between 84.5 to 26 kiloDalton
s.
The virus seems to remain latent within the host until the host is stressed. Virons first appear in the nucleus
. This is followed by the disintegration of the host nucleus and cytoplasm
and their replacement by paracrystalline structures composed of virons. These structures first appear in association with the mitochondria. After the nucleus and cytoplasm have been replaced the cell wall breaks down followed with release of virons into the medium. Vertical transmission also appears to be possible.
Virus
A virus is a small infectious agent that can replicate only inside the living cells of organisms. Viruses infect all types of organisms, from animals and plants to bacteria and archaea...

Virology
The viron is non enveloped, isosahedral with a diameter of 60 nanometers (nm).The genome is non segmented, linear double stranded DNA and ~25.5 kilobases in length. It has a guanine
Guanine
Guanine is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine . In DNA, guanine is paired with cytosine. With the formula C5H5N5O, guanine is a derivative of purine, consisting of a fused pyrimidine-imidazole ring system with...
+ cytosine
Cytosine
Cytosine is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine . It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached . The nucleoside of cytosine is cytidine...

Cell nucleus
In cell biology, the nucleus is a membrane-enclosed organelle found in eukaryotic cells. It contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these...

Cytoplasm
The cytoplasm is a small gel-like substance residing between the cell membrane holding all the cell's internal sub-structures , except for the nucleus. All the contents of the cells of prokaryote organisms are contained within the cytoplasm...
