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.
Begomovirus is a genus of viruses, in the family Geminiviridae. They are plant viruses that as a group have a very wide host range, infecting dicotyledonous plants. Worldwide they are responsible for a considerable amount of economic damage to many important crops such as tomatoes, beans, squash, cassava and cotton. There are 445 species in this genus.
Tombusvirus is a genus of viruses, in the family Tombusviridae. Plants serve as natural hosts. There are 17 species in this genus. Symptoms associated with this genus include mosaic. The name of the genus comes from Tomato bushy stunt virus.
Turnip yellow mosaic virus (TYMV) is an isometric Tymovirus of the family Tymoviridae. Its host range is confined almost entirely to plants in the genus Brassica in western Europe, which includes cabbages, cauliflower and broccoli. Infection causes bright yellow mosaic disease showing vein clearing and mottling of plant tissues.
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.
Pelargonium flower break virus (PFBV) is a plant pathogenic virus of the family Tombusviridae.
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.
Potexvirus is a genus of pathogenic viruses in the order Tymovirales, in the family Alphaflexiviridae. Plants serve as natural hosts. There are 48 species in this genus, three of which are assigned to a subgenus. Diseases associated with this genus include: mosaic and ringspot symptoms. The genus name comes from POTato virus X).
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.
Malva mosaic virus is a plant pathogenic virus of the family Alphaflexiviridae. It was discovered in 2008 and infects the common mallow. Its genome is about 6,800 nucleotides in length and it contains five major open reading frames.
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.
Anulavirus is a genus of viruses, in the family Bromoviridae. Pelargonium serve as natural hosts. There are two species in this genus.
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.
Caulimovirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include: vein-clearing or banding mosaic.
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.
