TheInfoList



OR:

''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family (biology), family Cactaceae. Prickly pears are also known as ''tuna'' (fruit), ''sabra'', ''nopal'' (paddle, plural ''nopales'') from the Nahuatl word for the pads, or nostle, from the Nahuatl word for the fruit; or paddle cactus. The genus is named for the Ancient Greece, Ancient Greek city of Opus, Greece, Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary art, culinary species is the Indian fig opuntia (''O. ficus-indica'').


Description

''O. ficus-indica'' is a large, trunk-forming, segmented cactus that may grow to with a crown of over in diameter and a trunk diameter of . Cladodes (large pads) are green to blue-green, bearing few spines up to or may be spineless. Prickly pears typically grow with flat, rounded cladodes (also called platyclades) containing large, smooth, fixed spines and small, hairlike prickles called glochids that readily adhere to skin or hair, then detach from the plant. The flowers are typically large, axillary, solitary, bisexual, and epiperigynous, with a perianth consisting of distinct, spirally arranged tepals and a hypanthium. The stamens are numerous and in spiral or whorled clusters, and the gynoecium has numerous inferior ovaries per carpel. Placentation is parietal, and the fruit is a berry with arillate seeds. Prickly pear species can vary greatly in habit; most are shrubs, but some, such as ''Opuntia galapageia'' of the Galápagos, are trees.

Chemistry

''Opuntia'' contains a range of phytochemicals in variable quantities, such as polyphenols, dietary minerals and betalains. Identified compounds under basic research include gallic acid, vanillic acid and catechins, as examples. The Sicilian prickly pear contains betalain, betanin, and indicaxanthin, with highest levels in their fruits.


Taxonomy

When Carl Linnaeus published ''Species Plantarum'' in 1753 – the starting point for modern botanical nomenclature – he placed all the species of cactus known to him in one genus, ''Cactus''. In 1754, the Scottish botanist Philip Miller divided them into several genera, including ''Opuntia''. He distinguished the genus largely on the form of its flowers and fruits. Considerable variation of taxonomy occurs within ''Opuntia'' species, resulting in names being created for variants or subtypes within a species, and use of DNA sequencing to define and isolate various species.


Species

''Opuntia'' Hybrid (biology), hybridizes readily between species. This can make classification difficult, yielding a reticulate phylogeny where different species come together in hybridization. ''Opuntia'' also has a tendency for polyploidy. The ancestral diploid state was 2n=22, but many species are hexaploid (6n = 66) or octaploid (8n = 88).

Chollas

Chollas, now recognized to belong to the distinct genus ''Cylindropuntia'', are distinguished by having cylindrical, rather than flattened, stem segments with large barbed spines. The stem joints of several species, notably the jumping cholla (''C. fulgida''), are very brittle on young stems, readily breaking off when the barbed spines stick to clothing or animal fur as a method of vegetative reproduction. The barbed spines can remain embedded in the skin, causing discomfort and sometimes injury.


Breeding

One of the ancient homes of the cactus pear, Mexico, ran a crop breeding program, breeding program in the 1960s. This effort at the Antonio Narro Agrarian Autonomous University (Universidad Autónoma Agraria Antonio Narro, UAAAN) produced improvements in some traits including cold-hardiness.


Distribution and habitat

Like most true cactus species, prickly pears are native only to the Americas. Through human actions, they have since been introduced to many other areas of the world. Prickly pear species are found in abundance in Mexico, especially in the central and western regions, and in the Caribbean islands (West Indies). In the United States, prickly pears are native to many areas of the arid, semiarid, and drought-prone Western United States, Western and South Central United States, South Central United States, including the lower elevations of the Rocky Mountains and southern Great Plains, where species such as ''Opuntia phaeacantha, O. phaeacantha'' and ''Opuntia polyacantha, O. polyacantha'' become dominant, and to the desert Southwest, where several types are endemic. Prickly pear cactus is also native to sandy coastal beach scrub environments of the East Coast of the United States, East Coast from Florida to southern Connecticut, where ''Opuntia humifusa, O. humifusa'', ''Opuntia stricta, O. stricta'', and ''Opuntia pusilla, O. pusilla'', are found from the East Coast south into the Caribbean and the Bahamas. Additionally, the eastern prickly pear is native to the midwestern "sand prairies" nearby major river systems, such as the Mississippi, Illinois, and Ohio rivers. The plant also occurs naturally in hilly areas of southern Illinois, and sandy or rocky areas of northern Illinois. ''Opuntia'' species are the most cold-tolerant of the lowland cacti, extending into western and southern Canada; one subspecies, Opuntia fragilis, ''O. fragilis'' var. ''fragilis'', has been found growing along the Beatton River in central British Columbia, southwest of Cecil Lake at 56° 17’ N latitude and 120° 39’ W longitude. Others are seen in the Kleskun Hills Natural Area of north-west Alberta at 55° 15’ 30’’ N latitude and 118° 30’ 36’’ W longitude. Prickly pears also produce a fruit, commonly eaten in Mexico and in the Mediterranean region, known as ''tuna''; it also is used to make ''aguas frescas''. The fruit can be red, wine-red, green, or yellow-orange. In the Galápagos Islands, the Galápagos prickly pear, Opuntia galapageia, ''O. galapageia'', has previously been treated as a number of different species, but is now only divided into varieties and subvarieties. Most of these are confined to one or a few islands, so they have been described as "an excellent example of adaptive radiation". On the whole, islands with tall, trunked varieties have giant tortoises, and islands lacking tortoises have low or prostrate forms of ''Opuntia''. Prickly pears are a prime source of food for the common giant tortoises in the Galápagos Islands, so they are important in the food web. Charles Darwin was the first to note that these cacti have thigmotaxis, thigmotactic anthers; when the anthers are touched, they curl over, depositing their pollen. This movement can be seen by gently poking the anthers of an open ''Opuntia'' flower. The same trait has convergent evolution, evolved convergently in other species (e.g. ''Lophophora''). The first introduction of prickly pears into Australia is ascribed to Governor Arthur Phillip, Phillip and the earliest colonists in 1788. Brought from Brazil to Sydney, prickly pear grew in Sydney, New South Wales, where they were rediscovered in a farmer's garden in 1839. They appear to have spread from New South Wales and caused great ecological damage in the eastern states. They are also found in the Mediterranean region of Northern Africa, especially in Algeria, Morocco and Tunisia, where they grow all over the countryside, and in parts of Southern Europe, especially Spain, where they grow in the east, south-east, and south of the country, and also in Malta, where they grow all over the islands. They can be found in enormous numbers in parts of South Africa, where they were introduced from South America. Prickly pears are considered an invasive species in Prickly pears in Australia, Australia, Ethiopia, South Africa, and Hawaii, among other locations. Prickly pears (mostly ''O. stricta'') were originally imported into Europe during the 1500s and Australia in the 18th century for gardens, and were later used as a natural agricultural fencingPatterson, Ewen K. 1936. The World's First Insect Memorial. "The Review of the River Plate", December pp. 16–17 and in an attempt to establish a cochineal dye industry. In Australia, they quickly became a widespread invasive weed, eventually converting of farming land into an impenetrable green jungle of prickly pear, in places high. Scores of farmers were driven off their land by what they called the "green hell"; their abandoned homes were crushed under the cactus growth, which advanced at a rate of per year. In 1919, the Government of Australia, Australian federal government established the Commonwealth Prickly Pear Board to coordinate efforts with state governments to eradicate the weed. Early attempts at mechanical removal and poisonous chemicals failed, so in a last resort, biological control was attempted. The moth ''Cactoblastis cactorum'', from South America, whose larvae eat prickly pear, was introduced in 1925 and rapidly reduced the cactus population. Alan Parkhurst Dodd, Alan Dodd, the son of the noted entomologist Frederick Parkhurst Dodd, was a leading official in combating the prickly pear menace. A memorial hall in Chinchilla, Queensland, commemorates the moth. The release of cochineal insects that eat the cactus and simultaneously kill the plant has proven an effective measure for combatting the spread. Natural distribution occurs via consumption and seed dispersal by many animals, including antelopes, nonhuman primates, elephants, birds, and humans. When ingested by elephants, the sharp components of the plant cause harm to the mouth, stomach, and intestines.


Ecology

''O. ficus-indica'' thrives in regions with mild winters having a prolonged dry spell followed by hot summers with occasional rain and relatively low humidity. A mean annual rainfall of provides good growth rates. ''O. ficus-indica'' proliferates in various soils ranging from subacid to subalkaline, with clay content not exceeding 15–20% and the soil well-drained. The shallow root system enables the plant to grow in shallow, loose soils, such as on mountain slopes. ''Opuntia'' spreads into large clonal colonies, which contribute to its being considered a noxious weed in some places. Animals that eat ''Opuntia'' include the prickly pear island snail and ''Cyclura'' rock iguanas. The fruit are relished by many arid-land animals, chiefly birds, which thus help distribute the seeds. ''Opuntia'' pathogens include the sac fungus ''Colletotrichum coccodes'' and Sammons' Opuntia virus, Sammons' ''Opuntia'' virus. The ant ''Crematogaster opuntiae'' and the spider ''Theridion opuntia'' are named because of their association with prickly pear cactus.


Toxicity

Although the plants are edible, the pointed hairs should not be eaten, and similar species with milky sap are suspect.


Uses


Nutrition

Raw opuntia leaves are 88% water, 10% carbohydrates, and less than 1% both of protein and fat. In a reference serving, raw leaves provide of food energy, 17% of the Daily Value (DV) for vitamin C, and 24% DV for magnesium, with no other micronutrients in significant content.


Regional food uses

The fruit of prickly pears, commonly called cactus fruit, cactus fig, Indian fig (meaning "Indigenous peoples of the Americas, Native American", not India), ''nopales'' or ''tuna'' in Spanish, is edible, although it must be peeled carefully to remove the small spines on the outer skin before consumption. If the outer layer is not properly removed, glochids can be ingested, causing discomfort of the throat, lips, and tongue, as the small spines are easily lodged in the skin. Indigenous peoples of the Americas, Native Americans like the Tequesta would roll the fruit around in a suitable medium (e.g. wikt:grit, grit) to "sandpaper, sand" off the glochids. Alternatively, rotating the fruit in the flame of a campfire or torch has been used to remove the glochids. Today, Parthenocarpy, parthenocarpic (seedless) cultivars are also available. The seeds can be used for flour. In Mexico, prickly pears are often used to make appetizers, soups, salads, entrees, vegetable dishes, breads, desserts, beverages, candy, fruit preserves, jelly, and drinks. The young Plant stem, stem segments, usually called pads or ''nopales'', are also edible in most species of ''Opuntia''. They are commonly used in Mexican cuisine in dishes such as ''huevos con nopales'' (egg (food), eggs with nopal), or ''tacos de nopales''. ''Nopales'' are also an important ingredient in New Mexican cuisine. In 2009 it was introduced as a cheaper alternative to corn for the production of tortillas and other corn products. They can also be pickled. ''Opuntia ficus-indica'' has been introduced to Europe, and flourishes in areas with a suitable climate, such as the south of France and southern Italy: In Sicily, they are referred to as ''fichi d'India'' (Italian literal translation of Indian fig) or ''ficurinia'' (Sicilian language literal translation of Indian fig). In Sardinia, they are called ''figumorisca'' – Moorish figs), the same denomination they receive along the Catalan_language, Catalan-speaking regions of the Western Mediterranean, ''figa de moro''. They can be found also in the Struma River in Bulgaria, in southern Portugal and Madeira (where they are called ''tabaibo'', ''figo tuno'', or "Indian figs"), in Andalusia, Spain (where they are known as ''higos chumbos''). In Greece, it grows in such places as the Peloponnese region, Ionian Islands, or Crete, and its figs are known as ''frangosyka'' (Frankish, i.e. Western European, figs) or ''pavlosyka'' (Paul's figs), depending on the region. In Albania, they are called ''fiq deti'' translated as 'sea figs', and are present in the south-west shore. The figs are also grown in Cyprus, where they are known as ''papoutsósyka'' or ''babutsa'' (shoe figs). The prickly pear also grows widely on the islands of Malta, where it is enjoyed by the Maltese as a typical summer fruit (known as ''bajtar tax-xewk'', literally 'spiny figs'), as well as being used to make the popular liqueur known as ''bajtra''. The prickly pear is so commonly found in the Maltese islands, it is often used as a dividing wall between many of Malta's characteristic terraced fields in place of the usual rubble walls. The prickly pear was introduced to Eritrea during the period of Italian colonisation between 1890 and 1940. It is locally known there as ''beles'' and is abundant during the late summer and early autumn (late July through September). The ''beles'' from the holy monastery of Debre Bizen is said to be particularly sweet and juicy. In Morocco, Tunisia, Libya, Saudi Arabia, Jordan, and other parts of North Africa and the Middle East such as Israel, prickly pears of the yellow and orange varieties are grown by the side of farms, beside railway tracks and other otherwise noncultivable land. It is sold in summer by street vendors, and is considered a refreshing fruit for that season. In Libya, it is a popular summer fruit and called by the locals ''Hindi'', which literally means ''Indian''. ''Tungi'' is the local Saint Helena, St. Helenian name for cactus pears. The plants (Opuntia ficus-indica, Indian fig opuntia) were originally brought to the island by the colonial ivory traders from East Africa in the 1850s. ''Tungi'' cactus now grows wild in the dry coastal regions of the island. Three principal cultivars of ''tungi'' grow on the island: the 'English' with yellow fruit; the 'Madeira' with large red fruit; and the small, firm 'spiny red'.Tungi also gives its name to a local Spirit distilled at The St Helena distillery at Alarm Forest, the most remote distillery in the world, made entirely from the opuntia cactus. Cactus pear is being promoted and researched by ICARDA for India, Jordan, and Pakistan especially. It is an underappreciated crop in these countries and has undergone recent expansion in cultivated area. In some particularly promising areas of India and Pakistan it has given a 30% increase in milk yield /hectare (/acre).


Folk medicine

In Mexican folk medicine, its pulp and juice are considered treatments for wounds and inflammation of the digestive tract, digestive and urinary tracts, although there is no evidence-based medicine, high-quality evidence for any clinical benefit of using opuntia for these purposes. Prior to modern medicine, Native Americans and Mexicans primarily used ''Opuntia'' as a coagulant for open wounds, using the pulp of the stem either by splitting the stem or scraping out the pulp. In one recent study, it was found that ''Opuntia'' aided in the prevention or slow down of diabetes, obesity, metabolic syndrome, cardiovascular disease, and some cancers. The results of the group that was taking ''Opuntia'' showed a reduction in BMI, body composition, and waist circumference when compared to the placebo group.


Other uses


In dye production

''Dactylopius coccus'' is a scale insect from which cochineal dye is derived. ''D. coccus'' itself is native to tropical and subtropical South America and Mexico. This insect, a primarily Sessility (zoology), sessile parasite, lives on cactus, cacti from the genus ''Opuntia'', feeding on moisture and nutrients in the cactus sap. The insect produces carminic acid, which deters predation by other insects. The carminic acid can be extracted from the insect's body and eggs to make the red dye. Cochineal is used primarily as a red food colouring and for cosmetics. The cochineal dye was used by the Aztec and Maya civilization, Maya peoples of Central and North America, and by the Inca in South America. Produced almost exclusively in Oaxaca, Oaxaca, Oaxaca, Mexico, by indigenous producers, cochineal became Mexico's second-most valued export after silver. The dyestuff was consumed throughout Europe, and was so highly valued, its price was regularly quoted on the London and Amsterdam Commodity Exchanges. The biggest producers of cochineal are Peru, the Canary Islands, and Chile. Current health concerns over artificial food additives have renewed the popularity of cochineal dyes, and the increased demand is making cultivation for insect farming an attractive opportunity in other regions, such as in Mexico, where cochineal production had declined again owing to the numerous natural enemies of the scale insect. Apart from cochineal, the red dye betanin can be extracted from some ''Opuntia'' plants themselves.


For animal fodder

Cactus is used as a fodder crop for animals in arid and dryland regions. Some farmers prepare it with a fermentation produce, to remove the spines, and increase the digestibility.


As a source of "vegan leather"

The thick skin of nopal cactus can be harvested as an environmentally-friendly leather replacement.


For fuel

Bioethanol can be produced from some ''Opuntia'' species.


For bioplastic

Nopal juice can be used to produce bioplastic.


Culture

The prickly pear cactus has been used for centuries both as a food source and a natural fence that keeps in livestock and marks the boundaries of family lands. They are resilient and often grow back following removal. The 1975–1988 version of the Coat of arms of Malta#Emblem between 1975 and 1988, emblem of Malta also featured a prickly pear, along with a Dgħajsa, traditional ''dgħajsa'', a shovel and pitchfork, and the rising sun. The cactus lends its name to a song by British jazz/classical group Portico Quartet. The song "My Rival", on the album ''Gaucho (album), Gaucho'' by the American jazz-pop group Steely Dan begins with the words, "The wind was driving in my face/The smell of prickly pear." In the fall of 1961, Cuba had its troops plant an barrier of ''Opuntia'' cactus along the northeastern section of the fence surrounding the Guantanamo Bay Naval Base to stop Cubans from escaping Cuba to take refuge in the United States. This was dubbed the "Cactus Curtain", an allusion to Europe's Iron Curtain and the Bamboo Curtain in East Asia. Uruguayan-born footballer Bruno Fornaroli is nicknamed prickly pear due to his sometimes spiky hairstyles.


Mexico

The coat of arms of Mexico depicts a Mexican golden Eagle (heraldry), eagle, perched upon an ''Opuntia'' cactus, holding a rattlesnake. According to the official history of Mexico, the coat of arms is inspired by an Aztec legend regarding the founding of Tenochtitlan. The Aztecs, then a nomadic tribe, were wandering throughout Mexico in search of a divine sign to indicate the precise spot upon which they were to build their capital. Their god Huitzilopochtli had commanded them to find an eagle devouring a snake, perched atop a cactus that grew on a rock submerged in a lake. After 200 years of wandering, they found the promised sign on a small island in the swampy Lake Texcoco. There they founded their new capital, Tenochtitlan. The cactus (''O. ficus-indica''; Nahuatl: ''tenochtli''), full of fruits, is the symbol for the island of Tenochtitlan.


Israeli-born Jew

The cactus fig is called ''tzabar'' in Hebrew ( he, צבר). This cactus is also the origin of the term "''Sabra (person), Sabra''" used to describe any Israeli Jews, Jew born in Israel. The allusion is to a thorny, spiky skin on the outside, but a soft, sweet interior, suggesting, though the Israeli Sabras are rough on the outside, they are sweet and sensitive once one gets to know them. This term is might be derived from an Arabic word for this cactus صبار ''ṣubbār'', where the related term ''sabr'' also translates to "patience" or "tenacity".
