Carlavirus
''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. Description ''Carlavirus'' is described in the 9th report of the ICTV (2009). The genus is characterised by having six ORFs (open reading frames) including a TGB ( Triple Gene Block). The viruses are transmitted by insects. Taxonomy The genus was first proposed in the first report of the ICTV in 1971, as the 'Carnation latent virus group' but was renamed in 1975 as the 'Carlavirus group', and as the genus ''Carlavirus'' in 1995 (6th report). In 2005 (8th report) it was placed in the '' Flexiviridae'' family, having previously been unassigned. The current position in the 9th report (2009) as a genus of the family ''Betaflexiviridae'' derives from the subsequent subdivision of ''Flexivi ...

Garlic Common Latent Virus
''Garlic common latent virus'' (GarCLV) is a plant virus member of the genus ''Carlavirus'' that has been found infecting garlic globally. Detection of the virus in leek and onion has also been reported. Epidemiology GarCLV main transmission is through propagation material. As a result, it is often widespread among garlic crop. The virus single infection in garlic is usually symptomless, but in mixed infections with leek yellow stripe virus (LYSV, ''Potyvirus'') or onion yellow dwarf virus (OYDV, ''Potyvirus'') could form ‘garlic viral complex’ which increases severity of the other viruses infection. Other Allium spp. such as Allium caeruleum, Allium cristophii, Allium cyathophorum, Allium nutans, Allium schoenoprasum, Allium scorodoprasum, Allium senescens subsp. montanum, and Allium sphaerocephalon had also been reported to be infected by GarCLV. Genome The virus complete genome, excluding poly-(A) tail, is 8,353 nt long, and contains six open reading frame (ORFs). O ...

Daphne Virus S
Daphne virus S (DVS) is a plant virus that infects daphnes. Infection causes leaf distortion and chlorotic spot disease symptoms. Its genome is about 8,700 nucleotides in length and contains six open reading frames that encode for a viral replicase, a triple gene block and capsid A capsid is the protein shell of a virus, enclosing its genetic material. It consists of several oligomeric (repeating) structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may ... proteins.

Kalanchoe Latent Virus
''Kalanchoe'' , also written ''Kalanchöe'' or ''Kalanchoë'', is a genus of about 125 species of tropical, succulent plants in the stonecrop family Crassulaceae, mainly native to Madagascar and tropical Africa. A ''Kalanchoe'' species was one of the first plants to be sent into space, sent on a resupply to the Soviet Salyut 1 space station in 1979. The majority of kalanchoes require around 6-8 hours of sunlight a day; a few cannot tolerate this, and survive with bright, indirect sunlight to bright shade. Description Most are shrubs or perennial herbaceous plants, but a few are annual or biennial. The largest, ''Kalanchoe beharensis'' from Madagascar, can reach tall, but most species are less than tall. Kalanchoes open their flowers by growing new cells on the inner surface of the petals to force them outwards, and on the outside of the petals to close them. Kalanchoe flowers are divided into 4 sections with 8 stamens. The petals are fused into a tube, in a similar way to so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrangea Chlorotic Mottle Virus
''Hydrangea'', () commonly named the hortensia, is a genus of over 75 species of flowering plants native to Asia and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs tall, but some are small trees, and others lianas reaching up to by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. ''Hydrangea'' is derived from Greek and means ‘water vessel’ (from ''húdōr'' "water" + ''ángos'' or ''angeîon'' "vessel"), in reference to the shape of its seed capsules. The earlier name, ''Hortensia'', is a Latinised version of the French given name Hortense, honoring French astronomer and mathematician Nicole-Reine Hortense Lepaute. This claim is disputed in page 88 on citation 10 at Nicole-Reine Hortense Lepaute page, which says: "Larousse considers this an injustice, and remarks that it has led many persons to the erroneous notion tha ...

Hippeastrum Latent Virus
''Hippeastrum'' () is a genus of about 90 species and over 600 hybrids and cultivars of perennial herbaceous bulbous plants. They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and large red or purple flowers. ''Hippeastrum'' is a genus in the family Amaryllidaceae (subfamily Amaryllidoideae, tribe Hippeastreae, and subtribe Hippeastrineae). The name ''Hippeastrum'', given to it by William Herbert, means "knight's star", although precisely what Herbert meant by the name is not certain. For many years there was confusion among botanists over the generic names ''Amaryllis'' and ''Hippeastrum'', one result of which is that the common name amaryllis is mainly used for cultivars of this genus, often sold as indoor flowering bulbs particularly at Christmas in the northern hemisphere. By contrast the generic name ''Amaryllis'' applies to bulbs from South Africa, usually grown outdoors. The genus is native to tropical and subtropical regions of the Am ...
