Alternanthera Mosaic Virus
Alternanthera mosaic virus (AltMV) is a plant pathogenic virus. AltMV belongs to the virus genus '' Potexvirus'' and the virus family ''Alphaflexiviridae''. AltMV was first identified in 1999 in Queensland, Australia. The virus was found in ''Alternanthera pugens'' ''(Amaranthaceae)'', a weed found in both the southern USA and Australia. Since then, AltMV has been identified in various ornamental plants in Italy, the United States (Maryland and Pennsylvania, Florida, and New York), and Brazil. This virus has a close serological relationship (ELISA/antiserum to the capsid protein) with another well known ''Potexvirus'' called '' Papaya mosaic virus'' (PapMV). This relationship has led to several examples of misdiagnosis in the past.Eshenaur, B.C., V.E. Jarlfors, K.A. Kelly and J. O'Mara. 1995.

Helichrysum
The genus ''Helichrysum'' consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is '' Helichrysum orientale''. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Ancient Greek words (helios, sun) and (, gold). It occurs in Africa (with 244 species in South Africa), Madagascar, Australasia and Eurasia. The plants may be annuals, herbaceous perennials or shrubs, growing to a height of . The genus was a wastebasket taxon, and many of its members have been reclassified in smaller genera, most notably the Everlastings, now in the genus '' Xerochrysum''. Their leaves are oblong to lanceolate. They are flat and pubescent on both sides. The bristles of the pappus are scabrous, barbellate, or plumose. The receptacle (''base of the flower head'') is often smooth, with a fringed margin, or honey-combed, and resemble daisies. They may be in almost all colors, except blue. There are ...

Carica Papaya
The papaya (, ), papaw, () or pawpaw () is the plant species ''Carica papaya'', one of the 21 accepted species in the genus ''Carica'' of the family Caricaceae, and also the name of its fruit. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. It is grown in several countries in regions with a tropical climate. In 2022, India produced 38% of the world's supply of papayas. Etymology The word ''papaya'' derives from the Caribbean Taíno "paapaía" and is also the name for the plant. Some etymologists argue that the word comes from the Mayan "páapay-ya", which means "mottled sapote". However, the most commonly accepted etymology is the Taíno one, although it is possible that both word origins are interrelated. The name ''papaw'' or ''pawpaw'' is used alternatively for the fruit only in some regions, that name generally referring to ''Asimina triloba'', an unrelated tree and fruit.

Vigna Unguiculata
The cowpea (''Vigna unguiculata'') is an Annual plant, annual Herbaceous plant, herbaceous legume from the genus ''Vigna''. Its tolerance for sandy soil and low rainfall have made it an important crop in the Semi-arid climate, semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to Nitrogen fixation, fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Four subspecies of cowpeas are recognised, of which three are cultivated. A high level of Morphology (biology), morphological diversity is found within the species with large variations in the size, shape, and structure of the plant. Cowpeas can be erect, semierect (Trailing plant, trailing), or Climbing plant, climbing. The crop is mainly grown for its seeds, which are high in Protein (nutrient), ...

Citrullus Lanatus
The watermelon (''Citrullus lanatus'') is a species of flowering plant in the family Cucurbitaceae, that has a large, edible fruit. It is a scrambling and trailing vine-like plant, and is widely cultivated worldwide, with more than 1,000 varieties. Watermelons are grown in favorable climates from tropical to temperate regions worldwide for its large edible fruit, which is a berry with a hard rind and no internal divisions, and is botanically called a ''pepo''. The sweet, juicy flesh is usually deep red to pink, with many black seeds, although seedless varieties exist. The fruit can be eaten raw or pickled, and the rind is edible after cooking. It may also be consumed as a juice or an ingredient in mixed beverages. Kordofan melons from Sudan are the closest relatives and may be progenitors of modern, cultivated watermelons. Wild watermelon seeds were found in Uan Muhuggiag, a prehistoric site in Libya that dates to approximately 3500 BC. In 2022, a study was releas ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinnia Elegans
''Zinnia elegans'' ( syn. ''Zinnia violacea'') known as youth-and-age, common zinnia or elegant zinnia, is an annual flowering plant in the family Asteraceae. It is native to Mexico but grown as an ornamental in many places and naturalised in several places, including scattered locations in South and Central America, the West Indies, the United States, Australia, and Italy. Description The uncultivated plant grows to about in height. It has solitary flower heads about across. The purple ray florets surround black and yellow discs. The lanceolate leaves are opposite the flower heads. Flowering occurs during the summer months. History The species was first collected in 1789 at Tixtla, Guerrero, by Sessé and Mociño. It was formally described as ''Zinnia violacea'' by Cavanilles in 1791.

Helianthus Annuus
The common sunflower (''Helianthus annuus'') is a species of large annual forb of the daisy family Asteraceae. The common sunflower is harvested for its edible oily seeds, which are often eaten as a snack food. They are also used in the production of cooking oil, as food for livestock, as bird food, and as plantings in domestic gardens for aesthetics. Wild plants are known for their multiple flower heads, whereas the domestic sunflower often possesses a single large flower head atop an unbranched stem. Description The plant has an erect rough-hairy stem, reaching typical heights of . The tallest sunflower on record achieved . Sunflower leaves are broad, coarsely toothed, rough and mostly alternate; those near the bottom are largest and commonly heart-shaped. Flower The plant flowers in summer.

Vicia Faba
''Vicia faba'', commonly known as the broad bean, fava bean, or faba bean, is a species of vetch, a flowering plant in the pea and bean family Fabaceae. It is widely cultivated as a crop for human consumption, and also as a cover crop. Varieties with smaller, harder seeds that are fed to horses or other animals are called field bean, tic bean or tick bean. This legume is commonly consumed in many national and regional cuisines. Some people suffer from favism, a hemolytic response to the consumption of broad beans, a condition linked to a metabolic disorder known as G6PDD. Otherwise the beans, with the outer seed coat removed, can be eaten raw or cooked. With young seed pods, the outer seed coat can be eaten, and in very young pods, the entire seed pod can be eaten. Description ''Vicia faba'' is a stiffly erect, annual plant tall, with two to four stems that are square in cross-section. The leaves are long, pinnate with 2–7 leaflets, and glaucous (grey-green). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycopersicon Esculentum
The tomato (, ), ''Solanum lycopersicum'', is a plant whose fruit is an edible berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from and was domesticated in western South America. It was introduced to the Old World by the Spanish in the Columbian exchange in the 16th century. Tomato plants are vines, largely annual and vulnerable to frost, though sometimes living longer in greenhouses. The flowers are able to self-fertilise. Modern varieties have been bred to ripen uniformly red, in a process that has impaired the fruit's sweetness and flavor. There are thousands of cultivars, varying in size, color, shape, and flavor. Tomatoes are attacked by many insect pests and nematodes, and are subject to diseases caused by viruses and by mildew and blight fungi. The tomato has a strong savoury umami flavor, and is an important ingredient in cuisines around the world. It is used in pizz ...
