Query: What family does the purple heart plant belong to?
Tradescantia pallida is a species of spiderwort (a genus of New World plants) more commonly known as wandering jew or walking jew, a name it shares with the closely related species "T. fluminensis" and "T. zebrina". Other common names include purple secretia, purple-heart, and purple queen. It is native to the Gulf Coast region of eastern Mexico. Edward Palmer collected the type specimen near Ciudad Victoria, Tamaulipas in 1907.
Pomelo (the Asian fruit that was crossed with an orange to produce grapefruit) contains high amounts of furanocoumarin derivatives. Grapefruit relatives and other varieties of pomelo have variable amounts of furanocoumarin.
The pomelo, Citrus maxima or Citrus grandis, is the largest citrus fruit from the Rutaceae family. It is a natural (non-hybrid) citrus fruit, similar in appearance to a large grapefruit, native to South and Southeast Asia. The pomelo is one of the original citrus species from which the rest of cultivated citrus hybridized. The popular fruit is used in many Chinese festive celebrations throughout Southeast Asia.
"Stemphylium solani" is of greatest concern in tomatoes, potatoes, peppers, garlic, onions, and cotton, though a wide range of over 20 species have proven susceptible. In tomatoes and potatoes, the resulting disease is known as grey leaf spot. In alliums it is known as leaf blight. Additional hosts are listed below.In alliums, infection is first visible as oval white spots, 1–3 mm in length, scattered irregularly over the leaf surface. These spots grow into red or purple colored lesions with a yellow margin and finally progress to leaf wilting and necrosis. Experimentally infected plants have been shown to progress from initial infection to leaf necrosis within eight days. Infection is found only on the stems and leaves of plants. In tomatoes, "S. solani" symptoms begin as round to oval dark specks on both sides of the leaf with older leaves being affected first. Young lesions may have a yellow halo. As lesions age, they become gray, dry and brittle, eventually falling away to create shot-holing in the leaf. Severe infection results in leaf drop.
The pomelo ("Citrus maxima"), a second of the core species from which most citrus hybrids have derived, is native to southeast Asia. Among the hybrids deriving from mandarin/pomelo crosses, there is a direct correlation between the proportion of pomelo DNA in the hybrid and fruit size, while the more palatable mandarins are those that have received specific genes from pomelos that alter their acidity. Some of the more common pomelos are genetically pure, while a number have a single small region of introgressed mandarin DNA on one chromosome, the result of a cross followed by extensive backcrossing with pomelo.
The ponderosa lemon originated in roughly 1887, and is believed to come from a chance seedling grown in Hagerstown, Maryland. It was later named and introduced to the nursery trade in 1900. Though often referred to as a cross between the lemon and citron, a recent genomic analysis showed it to solely contain pomelo ("Citrus maxima") and citron ("Citrus medica") DNA, perhaps being an F2 hybrid. Thus they cannot derive from true lemons, which have a mandarin orange component.
Banksia petiolaris is a species of flowering plant of the family Proteaceae native to Western Australia, where it is found in sandy soils in the south coastal regions from Munglinup east to Israelite Bay. It was first described by Victorian state botanist Ferdinand von Mueller in 1864, and no subspecies are recognised. "B. petiolaris" is one of several closely related species that all grow as prostrate shrub, with horizontal stems and thick, leathery upright leaves. Those of this species can be viable for up to 13 years—the longest-lived of any flowering plant recorded. It bears yellow cylindrical flower spikes, known as inflorescences, up to high in spring. As the spikes age, they turn grey and develop up to 20 woody seed pods, known as follicles, each.
Common lemons are the product of orange/citron hybridization, and hence have pomelo ancestry, and although Key limes are papeda/citron hybrids, the more commercially prevalent Persian limes and similar varieties are crosses of the Key lime with lemons, and hence likewise have pomelo ancestry. These limes can also inhibit drug metabolism. Other less-common citrus species also referred to as lemons or limes are genetically distinct from the more common varieties, with different proportions of pomelo ancestry.
The citron ("Citrus medica") is a large fragrant citrus fruit with a thick rind. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used widely in Asian cuisine, and also in traditional medicines, perfume, and for religious rituals and offerings. Hybrids of citrons with other citrus are commercially prominent, notably lemons and many limes.
The fruit is thought to have arisen in Southern China, where its name was recorded in the records of Jianchang during the Ming Dynasty, and its agricultural growth is widespread in Jiangxi province. Japanese oranges were cultivated from the cherry orange about 700 years ago. Genetic studies have found it to be closely related to the Huanglingmiao mandarin, carrying the same pomelo ("Citrus maxima") introgression, indicating that the two diverged from the same backcrossed domesticated ancestor. Under the Tanaka system of citrus taxonomy, it is a separate species, "Citrus kinokuni", while the Swingle system groups it with other pure and hybrid mandarins as a single species, "Citrus reticulata".
The Chinese government recently ranked the fruit as one of the best fruits in China.
Phytophthora infestans is an oomycete or water mold, a microorganism that causes the serious potato and tomato disease known as late blight or potato blight. (Early blight, caused by "Alternaria solani", is also often called "potato blight".) Late blight was a major culprit in the 1840s European, the 1845 Irish, and the 1846 Highland potato famines. The organism can also infect some other members of the Solanaceae. The pathogen is favored by moist, cool environments: sporulation is optimal at 12–18 °C in water-saturated or nearly saturated environments, and zoospore production is favored at temperatures below 15 °C. Lesion growth rates are typically optimal at a slightly warmer temperature range of 20 to 24 °C.
The hairpin banksia ("Banksia spinulosa") is a species of woody shrub, of the genus "Banksia" in the family Proteaceae, native to eastern Australia. Widely distributed, it is found as an understorey plant in open dry forest or heathland from Victoria to northern Queensland, generally on sandstone though sometimes also clay soils. It generally grows as a small shrub to in height, though can be a straggly tree to . It has long narrow leaves with inflorescences which can vary considerably in coloration; while the spikes are gold or less commonly yellowish, the emergent styles may be a wide range of colours – from black, purple, red, orange or yellow.
The dress is augmented by a long 5 metre (16-ft) veil, hand-embroidered with a variety of flowers on its hem, and symbolic crops of wheat. It was 3 metres wide. The veil took longer to create than the dress itself. Markle chose two favourite flowers – wintersweet ("Chimonanthus praecox"), which grows outside Nottingham Cottage at Kensington Palace, where she and Harry lived, and the California poppy ("Eschscholzia californica"), from where she was born – along with individual flowers representing the 53 countries of the Commonwealth, reflecting the couple's interest in the work of the Commonwealth. The countries and flowers are:Elizabeth Emanuel, co-designer of Diana, Princess of Wales's wedding gown, thought that the gown made a "really solid fashion statement" and thought that Waight Keller "should be pleased because Meghan looked absolutely stunning and beautiful." Waight Keller stated that Prince Harry told her "Oh my God. Thank you. She is absolutely magnificent."
All of these hybrids have in turn been bred back with their parent stocks or with other pure or hybrid citrus to form a broad array of fruits. Naming of these is inconsistent, with some bearing a variant of the name of one of the parents or simply another citrus with superficially-similar fruit, a distinct name, or a portmanteau of ancestral species. The Ponderosa lemon ("Citrus limon" × "medica") and Florentine citron ("Citrus x limonimedica") are both true lemon/citron hybrids, the Bergamot orange is a sweet orange/lemon hybrid and the Oroblanco is a grapefruit/pomelo mix, while tangelos are tangerine (mandarin)/pomelo or mandarin/grapefruit hybrids, orangelos result from grapefruit backcrossed with sweet orange, and a sweet orange backcrossed with a tangerine gives the tangor. One lumia, a member of the sweet lemons, is the product of crossing a lemon with a pomelo/citron hybrid, though another lumia variety, the Pomme d'Adam, is a micrantha/citron cross, like the Key lime. The most common and commercially popular 'limes', the Persian limes, are Key lime/lemon hybrids that combine the genetic lineages of four ancestral citrus species: mandarin, pomelo, citron and micrantha.
BABA was first found to increase the resistance of plants to disease in 1960, when it was observed that it decreased late blight of tomato. Further tests were made in the 1960s, but it was not until the 1990s that interest in the compound was renewed. Since then, it has been shown to be effective in many different pathosystems under controlled conditions. Both perennial and annual plants have been shown to respond, as well as both monocot and dicot plants in the Solanaceae, Cucurbitaceae, Compositae, Fabaceae, Brassicaceae, Graminae, Malvaceae, Rosaceae, and Vitaceae families. Pathogen groups that have shown a response include viruses, bacteria, nematodes, fungi and oomycetes. It has also been shown to be effective in the field at protecting potato and tomato plants from late blight, grape vines from "Plasmopara viticola" and melons from "Monosporascus cannonballus".
Research has shown that "Pantoea agglomerans" can serve as a plant pathogen competitor for the management of plant diseases. Fire blight, a plant disease caused by bacterium "Erwinia amylovora," is commonly found in pear and apple crops. After coming in contact with "Erwinia amylovora", "Pantoea agglomerans" produces antibiotic properties that are toxic to the fire blight-inducing bacterium. It has been identified that it is possible that habitat modification or exclusion may also play a role in the effectiveness of the antibiosis of the fire blight biological control.
Indigenous plant life include numerous species of flowering plants including the endangered phayom, "Hopea ferrea" and "Dalbergia oliveri", the vulnerable "Hopea odorata" and Sumatran pine, and a variety of conifers and clubmosses. Near threatened birds include the Siamese fireback and Oriental darter. The Siamese fireback has been nominated to be the national bird of Thailand.
The fruit's English name "citron" derives ultimately from Latin, "citrus", which is also the origin of the genus name.
Plants vs. Zombies Heroes is a digital collectible card game in the "Plants vs. Zombies" series, developed by PopCap Games and published by Electronic Arts. On March 10, 2016, it underwent a soft launch in some countries on iOS, before being internationally released on October 18, 2016. This is the first mobile release in the "Plants vs Zombies" series in which players can play as either a Plant or a Zombie.
Algae comprise several different groups of organisms which produce food by photosynthesis and thus have traditionally been included in the plant kingdom. The seaweeds range from large multicellular algae to single-celled organisms and are classified into three groups, the brown, red and green algae. There is good evidence that the brown algae evolved independently from the others, from non-photosynthetic ancestors that formed endosymbiotic relationships with red algae rather than from cyanobacteria, and they are no longer classified as plants as defined here.
Research and development in managing "P. ramorum" in nursery settings extends from "P. ramorum" in the individual plant, to "P. ramorum" in the nursery environment, to the pathogen’s movement across state and national borders in infected plants.
Lythrum salicaria (purple loosestrife) is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife, or purple lythrum.
Galactites tomentosa (purple milk thistle) is a biennial herbaceous plant belonging to the genus "Galactites" of the Asteraceae family.
Caladenia hillmanii, commonly known as purple-heart fingers, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It is a ground orchid with a single leaf and one or two bright pink flowers with a reddish-purple labellum with darker bars.
Triphysaria micrantha is a species of flowering plant in the broomrape family known by the common name purplebeak owl's-clover. It is endemic to California, where it is known from the grasslands of the Central Valley and the foothills to the east and west. It an annual herb producing a hairy, glandular, purple-colored stem up to about 15 centimeters in maximum height. Like many species in its family it is a facultative root parasite on other plants, attaching to their roots via haustoria to tap nutrients. Its greenish to red-purple leaves are up to 2.5 centimeters long and are sometimes divided into a few narrow, pointed lobes. The inflorescence is a spike of flowers a few centimeters in length. Each flower has a narrow purple upper lip and a wide lower lip which is divided into yellowish or white pouches, often with purple markings on the lower parts.
