Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus Geranium. The family includes both the genus Geranium and the garden plants called geraniums, which modern botany classifies as genus Pelargonium, along with other related genera.
Variegation is the appearance of differently coloured zones in the leaves and sometimes the stems and fruit of plants. Species with variegated individuals are sometimes found in the understory of tropical rainforests, and this habitat is the source of a number of variegated houseplants. Variegation is caused by mutations that affect chlorophyll production or by viruses, such as mosaic viruses, which have been studied by scientists. The striking look of variegated plants is desired by many gardeners, and some have deliberately tried to induce it for aesthetic purposes. There are a number of gardening books about variegated plants, and some gardening societies specialize in them.
Caulimoviridae is a family of viruses infecting plants. There are 94 species in this family, assigned to 11 genera. Viruses belonging to the family Caulimoviridae are termed double-stranded DNA (dsDNA) reverse-transcribing viruses i.e. viruses that contain a reverse transcription stage in their replication cycle. This family contains all plant viruses with a dsDNA genome that have a reverse transcribing phase in their lifecycle.
Petuvirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There is only one species in this genus: Petunia vein clearing virus. Diseases associated with this genus include: plants: chlorotic vein clearing, leaf malformation.
Carnation vein mottle virus is a plant pathogenic virus of the family Potyviridae.
Cassava vein mosaic virus (CsVMV) is a plant pathogenic virus of the family Caulimoviridae.
Chilli veinal mottle virus (ChiVMV) is a plant pathogenic virus of the family Potyviridae.
Peanut green mosaic virus is a plant pathogenic virus of the family Potyviridae. A virus belonging to the potyvirus group known as the peanut green mosaic virus can be observed in the Chittoor district in Andhra Pradesh, India. Infection can be seen across groundnut, French bean, and soy bean plants. Three virus isolates produced different symptoms within the host. Based on tests performed on Phaseolus vulgaris or green beans, it was concluded that all three strains cause local lesions on inoculated leaves. However, one virus caused a non-systemic infection (NS), another caused systemic mosaic (SM), and the third caused systemic venial necrosis (SN). Infection is predominantly established in young leaflets. NS strains produced light and dark spots on its host, but no effect on growth and leaflet size observed. SM strains produced chlorotic spots and did impair leaflet size and plant growth. SN strains produced severe vein clearing and impaired growth in leaflet and plant size. Various types of antisera work on this virus.
Pelargonium line pattern virus (PLPV) is a plant pathogenic virus of the family Tombusviridae.
Pelargonium zonate spot virus (PZSV) is a plant pathogenic virus, classified in the Bromoviridae family, genus Anulavirus.
Sowthistle yellow vein virus (SYVV) is a plant-pathogenic virus of the family Rhabdoviridae. It infects the sowthistle, Sonchus oleraceous. As of May 2022, the formal species name is Betanucleorhabdovirus venasonchi.
Strawberry vein banding virus (SVBV) is a plant pathogenic virus and a member of the family Caulimoviridae.
Raspberry vein chlorosis virus (RVCV) is a plant pathogenic virus of the family Rhabdoviridae.
Carlavirus, formerly known as the "Carnation latent virus group", is a genus of viruses in the order Tymovirales, in the family Betaflexiviridae. Plants serve as natural hosts. There are 53 species in this genus. Diseases associated with this genus include: mosaic and ringspot symptoms.
Malva vein clearing virus also known as MVCV is a species of Potyvirus in the family Potyviridae that was isolated in 1957 from Malva sylvestris in Germany which is transmitted by the aphids Aphis umbrella and Myzus persicae. The insects mechanically inoculate the malvaceous hosts.
Soybean vein necrosis orthotospovirus is a plant pathogenic virus of soybeans. SVNV is a relatively new virus, which was discovered in Tennessee in 2008 and has recently been found in many US states from the Southeast and East coast to some western states including CA. This pathogen initially causes intraveinal chlorosis (yellowing) in leaves. This chlorosis then spreads throughout the leaf and eventually these chlorotic areas can become necrotic. It is a member of the order Bunyavirales, family Tospoviridae and genus Orthotospovirus, which is the only genus within this virus family that infects plants. Like other members of Bunyavirales, this virus is enveloped and has a negative sense single-stranded RNA (−ssRNA) genome composed of three genomic segments. It encodes proteins on the M and S segments in an ambisense manner.
Holocacista varii is a moth of the family Heliozelidae. It was described by Wolfram Mey in 2011. It is found in South Africa.
Badnavirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are 67 species in this genus. Diseases associated with this genus include: CSSV: leaf chlorosis, root necrosis, red vein banding in young leaves, small mottled pods, and stem/root swelling followed by die-back. Infection decreases yield by 25% within one year, 50% within two years and usually kills trees within 3–4 years.
Cavemovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are three species in this genus. Diseases associated with this genus include: vein-clearing or banding mosaic.
Solendovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are two species in this genus. Diseases associated with this genus include: TVCV: vein-clearing symptoms in N. edwardsonii.
