Plantain Virus X
''Plantain virus X'' is a species of virus, part of the Potexvirus viral family. It infects the weed plaintain (''Plantago lanceolata''). DNA sequencing has shown it to be synonymous with Actinidia virus X, infecting kiwifruit (''Actinidia'' spp.) and blackcurrants (''Ribes nigrum''). The same research also found ''Plantain virus X'' infecting ''Capsicum annuum'' (sweet pepper) and the ornamental flower ''Browallia americana ''Browallia americana'', the Jamaican forget-me-not, amethyst flower, or bush violet, is a species of flowering plant. It is native to tropical Latin America, from Mexico and the Caribbean, south to Peru and Brazil. Forms are variable. Pictured ...''.

Potexvirus
''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''). Taxonomy ''Potexvirus'' contains one subgenus that has three species and 45 additional species unassigned to a subgenus. The following 48 species are assigned to the genus: * Subgenus: '' Mandarivirus'' ** '' Citrus yellow mottle-associated virus'' ** '' Citrus yellow vein clearing virus'' ** '' Indian citrus ringspot virus'' The following species are unassigned to a subgenus: *'' Allium virus X'' *'' Alstroemeria virus X'' *'' Alternanthera mosaic virus'' *''Ambrosia asymptomatic virus 1'' *'' Asparagus virus 3'' *''Babaco mosaic virus'' *'' Bamboo mosaic virus'' *'' Cactus virus X'' *'' Cassava Colombian symptomless virus'' *'' Cass ...

Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Spri ...

Plantago Lanceolata
''Plantago lanceolata'' is a species of flowering plant in the plantain family Plantaginaceae. It is known by the common names ribwort plantain, narrowleaf plantain, English plantain, ribleaf, lamb's tongue, and buckhorn. It is a common weed on cultivated or disturbed land. Description The plant is a rosette-forming perennial herb, with leafless, silky, hairy flower stems (). The basal leaves are lanceolate spreading or erect, scarcely toothed with 3-5 strong parallel veins narrowed to a short petiole. The flower stalk is deeply furrowed, ending in an ovoid inflorescence of many small flowers each with a pointed bract. Each inflorescence can produce up to two hundred seeds. Flowers are (calyx green, corolla brownish), 4 bent back lobes with brown midribs and long white stamens. It is native to temperate Eurasia, widespread throughout the British Isles, but scarce on the most acidic soils ( pH < 4.5). It is present and widespread in the Americas and Australia as an

Kiwifruit
Kiwifruit (often shortened to kiwi in North American, British and continental European English) or Chinese gooseberry is the edible berry of several species of woody vines in the genus '' Actinidia''. The most common cultivar group of kiwifruit (''Actinidia deliciosa'' 'Hayward') is oval, about the size of a large hen's egg: in length and in diameter. It has a thin, fuzzy, fibrous, tart but edible light brown skin and light green or golden flesh with rows of tiny, black, edible seeds. The fruit has a soft texture with a sweet and unique flavour. Kiwifruit is native to central and eastern China. The first recorded description of the kiwifruit dates to the 12th century during the Song dynasty. In the early 20th century, cultivation of kiwifruit spread from China to New Zealand, where the first commercial plantings occurred. The fruit became popular with British and American servicemen stationed in New Zealand during World War II, and later became commonly exported, first to ...

Blackcurrant
The blackcurrant (''Ribes nigrum''), also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically. It is winter hardy, but cold weather at flowering time during the spring may reduce the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. Breeding is common in Scotland, Poland, Lithuania, Latvia, Norway, and New Zealand to produce fruit with better eating qualities and bushes with greater hardiness and disease resistance. The raw fruit is particularly rich in vitamin C and polyphenols. Blackcurrants can be eaten raw but are usually cooked in sweet or savoury dishes. They are used to make jams, preserves, and syrups and are grown commercially for the ju ...

Capsicum Annuum
''Capsicum annuum'' is a species of the plant genus '' Capsicum'' native to southern North America, the Caribbean, and northern South America. This species is the most common and extensively cultivated of the five domesticated capsicums. The species encompasses a wide variety of shapes and sizes of peppers, including sweet bell peppers and some chili pepper varieties such as jalapeños, New Mexico chile, and cayenne peppers. Cultivars descended from the wild American bird pepper are still found in warmer regions of the Americas. In the past, some woody forms of this species have been called '' C. frutescens'', but the features that were used to distinguish those forms appear in many populations of ''C. annuum'' and are not consistently recognizable features in ''C. frutescens'' species. Characteristics Although the species name ''annuum'' means 'annual' (from the Latin ''annus'' "year"), the plant is not an annual but is frost tender. In the absence of winter frosts it ca ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, whic ...

National Center For Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics. GenBank NCBI had responsibility for making available the GenBan ...
