Passion Fruit Woodiness Virus
'' Passion fruit woodiness virus '' (PWV) is a plant pathogenic virus in the genus ''Potyvirus'' and the virus family ''Potyviridae''. Like other members of the genus ''Potyvirus'', PWV is a monopartite strand of positive-sense, single-stranded RNA surrounded by a capsid made for a single viral encoded protein. The virus is a filamentous particle that measures about 745 nm in length. This virus is transmitted by at least two species of aphids (''Myzus persicae'' and ''Aphis gossypii'' ) in a non-persistent manner and by mechanical inoculation. There is no evidence that this virus is transmitted in the seed. Like other potyviruses, this virus produces viral inclusions called cylindrical inclusions. These inclusions can be diagnostic in ''Passiflora spp''. (See #External links) Symptoms This virus was named for the symptoms seen in the fruit of infected ''P. edulis'' plants. The fruit can be distorted in appearance and the edible part of the fruit becomes thick and hard or “ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potyvirus
''Potyvirus'' is a genus of positive-strand RNA viruses in the family ''Potyviridae''. Plants serve as natural hosts. The genus is named after member virus ''potato virus Y''. Potyviruses account for about thirty percent of the currently known plant viruses. Like begomoviruses, members of this genus may cause significant losses in agricultural, pastoral, horticultural, and ornamental crops. More than 200 species of aphids spread potyviruses, and most are from the subfamily '' Aphidinae'' (genera ''Macrosiphum'' and ''Myzus''). The genus contains 190 species.

Potyviridae
''Potyviridae'' is a family of positive-strand RNA viruses that encompasses more than 30% of known plant viruses, many of which are of great agricultural significance. The family has 12 genera and 235 species, three of which are unassigned to a genus. Structure Potyvirid virions are nonenveloped, flexuous filamentous, rod-shaped particles. The diameter is around 12–15 nm, with a length of 200–300 nm. Genome Genomes are linear and usually nonsegmented, around 8–12kb in length, consisting of positive-sense RNA, which is surrounded by a protein coat made up of a single viral encoded protein called a capsid. All induce the formation of virus inclusion bodies called cylindrical inclusions (‘pinwheels’) in their hosts. These consist of a single protein (about 70 kDa) made in their hosts from a single viral genome product. Member viruses encode large polypeptides that are cleaved into mature proteins. In 5'–3' order these proteins are * P1 (a serine protea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, colon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passiflora
''Passiflora'', known also as the passion flowers or passion vines, is a genus of about 550 species of flowering plants, the type genus of the family Passifloraceae. They are mostly tendril-bearing vines, with some being shrubs or trees. They can be woody or herbaceous. Passion flowers produce regular and usually showy flowers with a distinctive corona. There can be as many as eight coronal series, as in the case of ''P. xiikzodz''. The flower is pentamerous and ripens into an indehiscent fruit with numerous seeds. List of species Distribution ''Passiflora'' has a largely neotropic distribution, unlike other genera in the family Passifloraceae, which includes more Old World species (such as the genus '' Adenia''). The vast majority of ''Passiflora'' are found in Mexico, Central America, the United States and South America, although there are additional representatives in Southeast Asia and Oceania. New species continue to be identified: for example, '' P. xishuangbannae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Links
An internal link is a type of hyperlink on a web page to another page or resource, such as an image or document, on the same website or domain. Hyperlinks are considered either "external" or "internal" depending on their target or destination. Generally, a link to a page outside the same domain or website is considered external, whereas one that points at another section of the same web page or to another page of the same website or domain is considered internal. These definitions become clouded, however, when the same organization operates multiple domains functioning as a single web experience, e.g. when a secure commerce website is used for purchasing things displayed on a non-secure website. In these cases, links that are "external" by the above definition can conceivably be classified as "internal" for some purposes. Ultimately, an internal link points to a web page or resource in the same root directory. Similarly, seemingly "internal" links are in fact "external" for ...

Passiflora Edulis
''Passiflora edulis,'' commonly known as passion fruit, is a vine species of passion flower native to southern Brazil through Paraguay and northern Argentina. It is cultivated commercially in tropical and subtropical areas for its sweet, seedy fruit. The fruit is a pepo, a type of berry, round to oval, either yellow or dark purple at maturity, with a soft to firm, juicy interior filled with numerous seeds. The fruit is both eaten and juiced, the juice often added to other fruit juices to enhance aroma. Etymology The passion fruit is so called because it is one of the many species of passion flower, the English translation of the Latin genus name, ''Passiflora''. Around 1700, the name was given by missionaries in Brazil as an educational aid while trying to convert the indigenous inhabitants to Christianity; its name was ''flor das cinco chagas'' or "flower of the five wounds" to illustrate the crucifixion of Christ, with other plant components also named after an emblem in the ...

Passiflora Foetida
''Passiflora foetida'' (common names: stinking passionflower, wild maracuja, bush passion fruit, wild water lemon, stoneflower, love-in-a-mist, or running pop) is a species of passion flower that is native to the southwestern United States (southern Texas and Arizona), Mexico, the Caribbean, Central America, and much of South America. It has been introduced to tropical regions around the world, such as Southeast Asia, South Asia, Hawaii, Africa, and The Maldives. It is a creeping vine like other members of the genus, and yields an edible fruit. The specific epithet, ''foetida'', means "stinking" in Latin and refers to the strong aroma emitted by damaged foliage. This passion flower tolerates arid ground, but favours moist areas. It is known to be an invasive species in some areas. This plant is also a widely grown perennial climber, and has been used in traditional medicine. Description The stems are thin and wiry, and are covered with minute sticky yellow hairs. Older stems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passiflora Caerulea
''Passiflora caerulea'', the blue passionflower, bluecrown passionflower or common passion flower, is a species of flowering plant native to South America. It has been introduced elsewhere. It is a vigorous, deciduous or semi-evergreen tendril vine growing to or more. Its leaves are palmate, and its fragrant flowers are blue-white with a prominent fringe of coronal filaments in bands of blue, white,yellow, and brown. The ovoid orange fruit, growing to , is edible, but is variously described as having a bland, undesirable, or insipid taste. In South America, the plant is known for its medicinal properties, and is used by both the Toba and the Maka peoples. Names The specific epithet ''caerulea'' means "blue" and refers to the blue coronal filaments.
