An RNA virus is a virus that has RNA as its genetic material. This nucleic acid is usually single-stranded RNA (ssRNA) but may be double-stranded RNA (dsRNA). Notable human diseases caused by RNA viruses include the common cold, influenza, SARS, MERS, COVID-19, Dengue Virus, hepatitis C, hepatitis E, West Nile fever, Ebola virus disease, rabies, polio, mumps, and measles.
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Kalanchoe, or kal-un-KOH-ee, or kal-un-kee, also written Kalanchöe or Kalanchoë, is a genus of about 125 species of tropical, succulent flowering plants in the family Crassulaceae, mainly native to Madagascar and tropical Africa. Kalanchoe was one of the first plants to be sent into space, sent on a resupply to the Soviet Salyut 1 space station in 1979.
Bromoviridae is a family of viruses. Plants serve as natural hosts. There are currently 36 species in this family, divided among 6 genera.
Kalanchoe beharensis is a plant species in the succulent genus Kalanchoe, and the family Crassulaceae. Kalanchoe beharensis is native to Madagascar.
White spot syndrome (WSS) is a viral infection of penaeid shrimp. The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world.
Bryophyllum is a group of plant species of the family Crassulaceae native to Madagascar. It is a section or subgenus within the genus Kalanchoe, and was formerly placed at the level of genus. This section is notable for vegetatively growing small plantlets on the fringes of the leaves; these eventually drop off and root. These plantlets arise from mitosis of meristematic-type tissue in notches in the leaves.
Talicada nyseus, the red Pierrot, is a small but striking butterfly found in the Indian subcontinent and South-East Asia belonging to the lycaenids, or blues family. The red Pierrots, often found perching on its larva host plant, Kalanchoe, are usually noticed due to their striking patterns and colors.
Kalanchoe daigremontiana, formerly known as Bryophyllum daigremontianum and commonly called mother of thousands, alligator plant, or Mexican hat plant is a succulent plant native to Madagascar. Like other members of Bryophyllum, it can propagate vegetatively from plantlets that develop on its leaf margins. All parts of this species contain a very toxic steroid known as daigremontianin.
Kalanchoë mosaic virus is a plant pathogenic virus of the family Potyviridae.
Kalanchoe blossfeldiana is a herbaceous and commonly cultivated house plant of the genus Kalanchoe native to Madagascar. It is known by the English common names flaming Katy, Christmas kalanchoe, florist kalanchoe and Madagascar widow's-thrill.
Kalanchoe pinnata, formerly known as Bryophyllum pinnatum, also known as the air plant, cathedral bells, life plant, miracle leaf, and Goethe plant is a succulent plant native to Madagascar, which is a popular houseplant and has become naturalized in tropical and subtropical areas. It is distinctive for the profusion of miniature plantlets that form on the margins of its leaves, a trait it has in common with some other members of Bryophyllum.
Orthotospovirus is a genus of negative-strand RNA viruses, in the family Tospoviridae of the order Bunyavirales, which infects plants. Tospoviruses take their name from the type species tomato spotted wilt orthotospovirus (TSWV) which was discovered in Australia in 1919. The type species remained the only member of the family until the early 1990s when genetic characterisation of plant viruses became more common. There are now at least twenty species in the genus with more being discovered on a regular basis. Member viruses infect over eight hundred plant species from 82 different families.
Kalanchoe gastonis-bonnieri is a species of flowering plant in the family Crassulaceae. They are called "palm beachbells" or "donkey ear plants" as they have leaves resembling the shape of a donkey's ear.
Badnavirus is a genus of viruses, in the family Caulimoviridae order Ortervirales. Plants serve as natural hosts. There are currently 59 species in this genus including the type species Commelina yellow mottle virus. 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.
Kalanchoe longiflora, also known as tugela cliff-kalanchoe or long-flower kalanchoe, is a species of the succulent genus Kalanchoe, in the family Crassulaceae. An obscure shrub native to South Africa, it is known for its multi-coloured foliage and yellow flowers, which bloom in autumn to winter.
Kalanchoe suarezensis is a species of Kalanchoe native to northern Madagascar.
Kalanchoe laetivirens is a species of Kalanchoe. It is most likely a hybrid between K. daigremontiana and K. laxiflora, and therefore a group of invalid names for such a hybrid, including Kalanchoe crenodaigremontiana, Kalanchoe crenato-daigremontiana, Bryophyllum crenodaigremontianum and Bryophyllum crenato-daigremontianum, are just synonyms of K. laetivirens.
Kalanchoe × houghtonii is a hybrid between K. daigremontiana and K. delagoensis. It is often confused with K. daigremontiana which has strongly cordate to auriculate or even peltate leaves, while the leaves of K. × houghtonii are narrower and the leaf base is attenuate, cuneate to weakly cordate or auriculate.
