Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms.
Okavirus is a genus of enveloped positive-strand RNA viruses which infect crustaceans. Host organisms are mostly shrimp. It is the only genus in the family Roniviridae. Viruses associated with the genus include: gill-associated virus (GAV) which causes reddening, biofouling with exoparasites, emaciation, and massive mortality; and yellow head virus (YHV) which causes yellow head, arrest of feeding, and massive mortality. The name is derived from the 'Oka' or lymphoid organ in which the viruses are commonly detected and in which pathology occurs during acute infections. Lymphoid organs are anatomical structures common to penaeid shrimp. There are three species in this genus.
Luteoviridae was a family of viruses. The family was abolished in 2020 based on evidence that its three genera and seven species unassigned to a genus belonged to two other, existing families.
Potyvirus is a genus of positive-strand RNA viruses in the family Potyviridae. Plants serve as natural hosts. The genus is named after member virus potato virus Y. Potyviruses account for about thirty percent of the currently known plant viruses. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, horticultural, and ornamental crops. More than 200 species of aphids spread potyviruses, and most are from the subfamily Aphidinae. The genus contains 190 species.
Ecological competence is a term that has several different meanings that are dependent on the context it is used. The term "Ecological competence" can be used in a microbial sense, and it can be used in a sociological sense.
Groundnut rosette virus (GRV) is a peanut pathogenic virus found in Sub-Saharan Africa. It is transmitted between plants by insect vectors such as the groundnut aphid.
Rudiviridae is a family of viruses with linear double stranded DNA genomes that infect archaea. The viruses of this family are highly thermostable and can act as a template for site-selective and spatially controlled chemical modification. Furthermore, the two strands of the DNA are covalently linked at both ends of the genomes, which have long inverted terminal repeats. These inverted repeats are an adaptation to stabilize the genome in these extreme environments.
Pecluvirus is a genus of viruses, in the family Virgaviridae. Cereal crops and graminaceous weeds serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: (SBWMV): green and yellow mosaic. The name of the genus is derived from Peanut clump virus: Peanut clump virus, giving rise to Pecluvirus.
Cucumovirus is a genus of viruses, in the family Bromoviridae. Plants serve as natural hosts. There are four species in this genus.
Leaky scanning is a mechanism used during the initiation phase of eukaryotic translation that enables regulation of gene expression. During initiation, the small 40S ribosomal subunit "scans" or moves in a 5' --> 3' direction along the 5'UTR to locate a start codon to commence elongation. Sometimes, the scanning ribosome bypasses the initial AUG start codon and begins translation at further downstream AUG start codons. Translation in eukaryotic cells according to most scanning mechanisms occurs at the AUG start codon proximal to the 5' end of mRNA; however, the scanning ribosome may encounter an “unfavorable nucleotide context” around the start codon and continue scanning.
Ampullaviridae is a family of viruses that infect archaea of the genus Acidianus. Only one genus in this family has been described, Bottigliavirus, which contains three species. The name of the family and genus is derived from the Latin word for bottle, ampulla, due to the virions having the shape of a bottle. The family was first described during an investigation of the microbial flora of hot springs in Italy.
Hukuchivirus is a genus of double-stranded DNA viruses that infect thermophilic bacteria. The genus was previously named Gammasphaerolipovirus.
Aphis craccivora, variously known as the cowpea aphid, groundnut aphid or black legume aphid, is a true bug in the family Aphididae. Originally of probable Palearctic origin, it is now an invasive species of cosmopolitan distribution.
Soymovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are four species in this genus.
Tymovirus is a genus of viruses in the order Tymovirales, in the family Tymoviridae. Plants serve as natural hosts. There are 28 species in this genus.
Riboviria is a realm of viruses that includes all viruses that use a homologous RNA-dependent polymerase for replication. It includes RNA viruses that encode an RNA-dependent RNA polymerase, as well as reverse-transcribing viruses that encode an RNA-dependent DNA polymerase. RNA-dependent RNA polymerase (RdRp), also called RNA replicase, produces RNA from RNA. RNA-dependent DNA polymerase (RdDp), also called reverse transcriptase (RT), produces DNA from RNA. These enzymes are essential for replicating the viral genome and transcribing viral genes into messenger RNA (mRNA) for translation of viral proteins.
Arfiviricetes is a class of viruses.
Durnavirales is an order of double-stranded RNA viruses which infect eukaryotes. The name of the group derives from Italian duplo which means double, rna for the type of virus, and -virales which is the suffix for a virus order.
Thaspiviridae is a family of spindle-shaped viruses that is not assigned to any higher taxonomic ranks. The family contains a single genus, Nitmarvirus, which contains a single species, Nitmarvirus NSV1.
Adnaviria is a realm of viruses that includes archaeal viruses that have a filamentous virion and a linear, double-stranded DNA genome. The genome exists in A-form (A-DNA) and encodes a dimeric major capsid protein (MCP) that contains the SIRV2 fold, a type of alpha-helix bundle containing four helices. The virion consists of the genome encased in capsid proteins to form a helical nucleoprotein complex. For some viruses, this helix is surrounded by a lipid membrane called an envelope. Some contain an additional protein layer between the nucleoprotein helix and the envelope. Complete virions are long and thin and may be flexible or a stiff like a rod.
