Higrevirus is a genus of viruses. Plants serve as natural hosts. There is currently only one species in this genus: the type species Hibiscus green spot virus 2. [1] [2]
Viruses in Higrevirus are non-enveloped, with bacilliform geometries. These viruses are about 30 nm wide and 50 nm long. Genomes are linear and segmented, tripartite, around 38.43.23.1kb in length. [1]

Viral replication is cytoplasmic. 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. Plants serve as the natural host. [1]

Closteroviridae is a family of viruses. Plants serve as natural hosts. There are four genera and 59 species in this family, seven of which are unassigned to a genus. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem.
Closterovirus, also known as beet yellows viral group, is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are 17 species in this genus. Diseases associated with this genus include: yellowing and necrosis, particularly affecting the phloem. This genus has a probably worldwide distribution and includes among other viral species the Beet yellows virus and Citrus tristeza virus, rather economically important plant diseases. At least some species require vectors such as aphids or mealybugs for their transmission from plant to plant.
Tobravirus is a genus of viruses, in the family Virgaviridae. Plants serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: SBWMV: green and yellow mosaic.
Cucumovirus is a genus of viruses, in the family Bromoviridae. Plants serve as natural hosts. There are four species in this genus.
Alphaflexiviridae is a family of viruses in the order Tymovirales. Plants and fungi serve as natural hosts. There are 65 species in this family, assigned to six genera. Diseases associated with this family include: mosaic and ringspot symptoms.
Gammaflexiviridae is a family of viruses in the order Tymovirales. Fungi serve as natural hosts. There is only one genus in the family, Mycoflexivirus, which has one species: Botrytis virus F.
Virgaviridae is a family of positive-strand RNA viruses. Plants serve as natural hosts. The name of the family is derived from the Latin word virga (rod), as all viruses in this family are rod-shaped. There are currently 59 species in this family, divided among seven genera.
Brambyvirus is a genus of viruses, in the family Potyviridae. Plants serve as natural hosts. There is only one species in this genus: Blackberry virus Y.
Alvernaviridae is a family of viruses. Dinoflagellates serve as natural hosts. There is only one genus in this family, Dinornavirus, which contains one species: Heterocapsa circularisquama RNA virus 01. Diseases associated with this family include: control of the host population possibly through lysis of the host cell.
Carmotetraviridae is a family of viruses; there is only one genus in this family, Alphacarmotetravirus, which has one species: Providence virus. Lepidopteran insects serve as natural hosts.
Permutotetraviridae is a family of viruses. Lepidopteran insects serve as natural hosts. The family contains one genus that has two species. Diseases associated with this family include: infection outcome varies from unapparent to lethal.

Velarivirus is a genus of viruses, in the family Closteroviridae. Plants serve as natural hosts. There are eight species in this genus. Diseases associated with this genus include: GLRaV-7: symptomless in white-berried grapevine cultivar from Albania. However, it induces leafroll symptoms onto grafted cv. cabernet.
Zeavirus is a genus of viruses, in the family Tombusviridae. Monocots plants serve as natural hosts. There is only one species in this genus: Maize necrotic streak virus.
