The tomato is definitely the edible berry of your plant Solanum lycopersicum, commonly known as a tomato plant. The species originated in western South America and Central The usa.[two][3] The Nahuatl (the language used by the Aztecs) word tomatl gave rise towards the Spanish word tomate, from which the English term tomato derived.[three][4] Its domestication and use as being a cultivated food stuff may have originated Together with the indigenous peoples of Mexico.[two][5] The Aztecs utilised tomatoes within their cooking at time from the Spanish conquest of your Aztec Empire, and after the Spanish encountered the tomato for The very first time immediately after their connection with the Aztecs, they brought the http://thinktomato.com plant to Europe. From there, the tomato was released to other aspects of the European-colonized world in the sixteenth century.[2]
Tomatoes are a major source of umami flavor.[6] The tomato is consumed in various means, raw or cooked, in many dishes, sauces, salads, and beverages. Although tomatoes are fruits—botanically categorized as berries—they are commonly used to be a vegetable component or aspect dish.[3]
Quite a few styles of the tomato plant are greatly developed in temperate climates around the world, with greenhouses letting to the production of tomatoes in the course of all seasons in the yr. Tomato crops commonly develop to one–three meters (three–10 ft) in top. They're vines that have a weak stem that sprawls and typically wants support.[two] Indeterminate tomato vegetation are perennials in their native habitat, but are cultivated as annuals. (Determinate, or bush, vegetation are annuals that quit rising at a particular peak and develop a crop unexpectedly.) The scale of the tomato may differ based on the cultivar, with A variety of one–10 cm (1/2–four in) in width.[2]

Etymology
The phrase tomato arises from the Spanish tomate, which subsequently comes from the Nahuatl word tomatl ['tomat??], that means 'the swelling fruit'.[4] The indigenous Mexican tomatillo is tomate (Nahuatl: tomatl Relating to this soundpronunciation (aid·data), meaning 'Fats drinking water' or 'Unwanted fat matter').[7] When Aztecs began to cultivate the fruit to be larger, sweeter and pink, they known as the new wide range xitomatl (or jitomates) (pronounced [?i?'tomat?]),[2] ('plump with navel' or 'Unwanted fat water with navel'). The scientific species title lycopersicum (from the 1753 guide, Species Plantarum) is of Greek origin (????pe?s????; lykopersikon), that means 'wolf peach'.
Pronunciation
The standard pronunciations of tomato are /t?'me?to?/ (usual in American English) and /t?'m??to?/ (regular in British English).[eight] The term's dual pronunciations ended up immortalized in Ira and George Gershwin's 1937 tune "Let us Simply call The entire Factor Off" ("You want /p?'te?to?/ and I like /p?'t??to?/ / You want /t?'me?to?/ And that i like /t?'m??to?/") and have become a image for nitpicking pronunciation disputes.[citation wanted] In this capacity, it's got even become an American and British slang expression: expressing "/t?'me?to? t?'m??to?/" when introduced with two alternatives can indicate "What is actually the primary difference?" or "It is really all the identical to me".[citation essential]

Tomatoes are considered a fruit or vegetable determined by context. In accordance with Encyclopedia Britannica, tomatoes are a fruit labeled in grocery shops like a vegetable due to (the taste) and nutritional purposes.[3]
Tomatoes basic and sliced
Botanically, a tomato is a fruit—a berry, consisting with the ovary, along with its seeds, of the flowering plant. Having said that, the tomato is taken into account a "culinary vegetable" since it has a Considerably lower sugar content material than culinary fruits; it is typically served as A part of a salad or most important training course of the food, rather then as being a dessert. Tomatoes are usually not the one food resource using this type of ambiguity; bell peppers, cucumbers, green beans, eggplants, avocados, and squashes of all kinds (for example zucchini and pumpkins) are all botanically fruit, however cooked as veggies. This has led to authorized dispute in America. In 1887, U.S. tariff legislation that imposed a responsibility on vegetables, but not on fruit, triggered the tomato's status to be a make any difference of authorized worth. In Nix v. Hedden, the U.S. Supreme Court docket settled the tariff controversy on May perhaps ten, 1893, by declaring the tomato is a vegetable, according to the favored definition that classifies greens by use—They're usually served with meal and not dessert.[nine] The Keeping of the circumstance applies only into the interpretation of your Tariff of 1883, and the court didn't purport to reclassify the tomato for botanical or other functions.
Botany
Description
Tomato flower
An unripe tomato increasing within the vine
Tomato plants are vines, originally decumbent, commonly developing 180 cm (six ft) or more over the ground if supported, Whilst erect bush types are bred, generally one hundred cm (three ft 3 in) tall or shorter. Indeterminate sorts are "tender" perennials, dying on a yearly basis in temperate climates (They are really originally indigenous to tropical highlands), Despite the fact that they might live up to three a long time within a greenhouse occasionally. Determinate forms are yearly in all climates.[citation required]
Tomato vegetation are dicots, and expand like a series of branching stems, by using a terminal bud on the tip that does the actual increasing. When that tip sooner or later stops rising, irrespective of whether as a consequence of pruning or flowering, lateral buds consider around and expand into other, absolutely useful, vines.[10]
Tomato vines are generally pubescent, which means coated with wonderful limited hairs. These hairs facilitate the vining approach, turning into roots anywhere the plant is in connection with the ground and moisture, particularly if the vine's relationship to its initial root has actually been ruined or severed.[citation wanted]
Most tomato plants have compound leaves, and therefore are termed normal leaf (RL) vegetation, but some cultivars have straightforward leaves known as potato leaf (PL) fashion as a consequence of their resemblance to that individual relative. Of RL vegetation, you will discover versions, which include rugose leaves, which happen to be deeply grooved, and variegated, angora leaves, which have supplemental colours where a genetic mutation results in chlorophyll to generally be excluded from some parts of the leaves.[eleven]
The leaves are ten–twenty five cm (4–10 in) long, odd pinnate, with 5 to nine leaflets on petioles,[twelve] Each individual leaflet as much as 8 cm (three in) prolonged, with a serrated margin; each the stem and leaves are densely glandular-hairy.[citation needed]
Their flowers, appearing to the apical meristem, hold the anthers fused along the perimeters, forming a column surrounding the pistil's fashion. Flowers in domestic cultivars could be self-fertilizing. The bouquets are 1–two cm (1/two–3/4 in) across, yellow, with five pointed lobes over the corolla; They are really borne inside of a cyme of three to twelve jointly.[citation essential]
Whilst in culinary phrases, tomato is viewed as a vegetable, its fruit is classified botanically being a berry.[thirteen] As a true fruit, it develops from the ovary on the plant immediately after fertilization, its flesh comprising the pericarp partitions. The fruit is made up of hollow Areas filled with seeds and dampness, called locular cavities. These change, between cultivated species, In keeping with style. Some smaller sized types have two cavities, globe-formed kinds generally have a few to five, beefsteak tomatoes have a great variety of lesser cavities, though paste tomatoes have not many, quite modest cavities.[fourteen][fifteen][sixteen]
For propagation, the seeds should come from a mature fruit, and be dried or fermented in advance of germination.[citation needed]
Classification
In 1753, Linnaeus positioned the tomato inside the genus Solanum (along with the potato) as Solanum lycopersicum. In 1768, Philip Miller moved it to its own genus, naming it Lycopersicon esculentum.[seventeen] This identify arrived into extensive use, but was technically in breach of your plant naming procedures because Linnaeus's species title lycopersicum still experienced precedence. Although the name Lycopersicum lycopersicum was prompt by Karsten (1888), this is not used mainly because it violates the Intercontinental Code of Nomenclature[eighteen] barring the use of tautonyms in botanical nomenclature. The corrected identify Lycopersicon lycopersicum (Nicolson 1974) was technically legitimate, considering that Miller's genus name and Linnaeus's species identify vary in specific spelling, but considering the fact that Lycopersicon esculentum has grown to be so well-known, it had been officially listed being a nomen conservandum in 1983, and might be the right title for your tomato in classifications which never position the tomato inside the genus Solanum.
Genetic evidence has now revealed that Linnaeus was suitable to put the tomato from the genus Solanum, creating Solanum lycopersicum the correct title.[one][19] The two names, even so, will most likely be found in the literature for quite a while. Two of the major factors for thinking of the genera different would be the leaf structure (tomato leaves are markedly various from another Solanum), plus the biochemistry (many of the alkaloids frequent to other Solanum species are conspicuously absent during the tomato). Alternatively, hybrids of tomato and diploid potato can be made while in the lab by somatic fusion, and therefore are partially fertile,[20] delivering proof with the near romance between these species.
Genetic modification
Major write-up: Genetically modified tomato
Tomatoes which were modified applying genetic engineering are actually made, and Despite the fact that none are commercially out there now, they have been in past times. The first commercially readily available genetically modified foodstuff was various tomato named the Flavr Savr, which was engineered to possess a lengthier shelf lifestyle.[21] Experts are continuing to acquire tomatoes with new features not located in pure crops, like greater resistance to pests or environmental stresses. Other projects purpose to complement tomatoes with substances which could offer you health and fitness Advantages or give better nourishment.
A world consortium of scientists from ten countries, among the them researchers within the Boyce Thompson Institute for Plant Investigate, began sequencing the tomato genome in 2004, and is also making a databases of genomic sequences and knowledge within the tomato and relevant vegetation.[22][23] A prerelease Edition with the genome was built out there in December 2009.[24] The genomes of its mitochondria and chloroplasts are also staying sequenced as A part of the challenge. The whole genome for the cultivar Heinz 1706 was revealed on 31 May 2012 in Nature.[25] Given that a number of other fruits, like strawberries, apples, melons, and bananas share the exact same properties and genes, scientists mentioned the released genome could assist to improve foods quality, food stuff safety and lower costs of most of these fruits.[26]

The Tomato Genetic Useful resource Center, Germplasm Means Information and facts Network, AVRDC, and numerous seed financial institutions world wide retail outlet seed representing genetic variants of worth to fashionable agriculture. These seed stocks can be found for genuine breeding and exploration attempts. While personal breeding efforts can produce handy results, the majority of tomato breeding perform is at universities and significant agriculture-similar corporations. These endeavours have resulted in sizeable regionally adapted breeding strains and hybrids, such as the Mountain series from North Carolina. Firms together with Heinz, Monsanto, BHNSeed, and Bejoseed have breeding programs that try to strengthen creation, size, form, colour, taste, illness tolerance, pest tolerance, nutritional worth, and diverse other attributes.[citation needed]
Record
Solanum lycopersicum var. lycopersicum: the oldest surviving tomato fruit and leaves. Page with the En Tibi Herbarium, 1558. Naturalis Leiden.
The wild ancestor in the tomato is native to western South The usa.[27] These wild versions were being the size of peas.[27] Aztecs and also other peoples in Mesoamerica were being the primary to own domesticated the fruit and applied within their cooking. The Spanish very first released tomatoes to Europe, the place they became Employed in Spanish foodstuff. In France, Italy and northern Europe, the tomato was to begin with developed as an ornamental plant. It absolutely was regarded with suspicion as a foodstuff due to the fact botanists acknowledged it for a nightshade, a relative of the toxic belladonna.[3] This was exacerbated by the conversation of your tomato's acidic juice with pewter plates.[28] The leaves and immature fruit is made up of tomatine, which in big portions can be toxic. Having said that, the ripe fruit contains no tomatine.[29]
Mesoamerica
The precise day of domestication is not known; by five hundred BC, it absolutely was now becoming cultivated in southern Mexico and possibly other parts.[30]:thirteen The Pueblo folks are believed to possess believed that individuals who witnessed the ingestion of tomato seeds have been blessed with powers of divination.[31] The large, lumpy assortment of tomato, a mutation from a smoother, smaller sized fruit, originated in Mesoamerica, and will be the immediate ancestor of some modern day cultivated tomatoes.[thirty]:fifteen
The Aztecs elevated quite a few kinds of tomato, with purple tomatoes referred to as xictomatl and inexperienced tomatoes named tomatl (Tomatillo).[32] In line with Bernardino de Sahagún he observed an excellent a number of tomatoes inside the Aztec current market at Tenochtitlán (Mexico Metropolis): “. . . big tomatoes, little tomatoes, leaf tomatoes, sweet tomatoes, big serpent tomatoes, nipple-formed tomatoes,” and tomatoes of all shades through the brightest purple on the deepest yellow.[33] Bernardino de Sahagún mentioned Aztecs cooking several sauces, some with and without having tomatoes of different measurements, serving them in metropolis marketplaces: "foods sauces, sizzling sauces; fried [food], olla-cooked [foodstuff], juices, sauces of juices, shredded [food] with chile, with squash seeds [most certainly Cucurbita pepo], with tomatoes, with smoked chile, with sizzling chile, with yellow chile, with gentle pink chile sauce, yellow chile sauce, hot chile sauce, with "chook excrement" sauce, sauce of smoked chile, heated [sauces], bean sauce; [he sells] toasted beans, cooked beans, mushroom sauce, sauce of compact squash, sauce of huge tomatoes, sauce of common tomatoes, sauce of various kinds of bitter herbs, avocado sauce."[34]
Spanish distribution
Spanish conquistador Hernán Cortés may perhaps have already been the first to transfer a small yellow tomato to Europe after he captured the Aztec city of Tenochtitlan, now Mexico City, in 1521. The earliest dialogue of your tomato in European literature appeared in a herbal published in 1544 by Pietro Andrea Mattioli, an Italian medical professional and botanist, who instructed that a brand new type of eggplant had been brought to Italy that was blood crimson or golden color when mature and could be divided into segments and eaten like an eggplant—that may be, cooked and seasoned with salt, black pepper, and oil. It was not right until ten many years afterwards that tomatoes ended up named in print by Mattioli as pomi d'oro, or "golden apples".[thirty]:13
Following the Spanish colonization of the Americas, the Spanish distributed the tomato during their colonies in the Caribbean. Additionally they took it towards the Philippines, from the place it unfold to southeast Asia after which you can all the Asian continent. The Spanish also brought the tomato to Europe. It grew quickly in Mediterranean climates, and cultivation commenced while in the 1540s. It was in all probability eaten Soon immediately after it absolutely was launched, and was absolutely getting used as food with the early 17th century in Spain.
China
The tomato was released to China, probably by means of the Philippines or Macau, during the 1500s. It had been specified the name fanqié (barbarian eggplant), as the Chinese named several foodstuffs released from abroad, but referring precisely to early introductions.[35]
Italy
The recorded history of tomatoes in Italy dates back again to no less than 31 October 1548, when the house steward of Cosimo de' Medici, the grand duke of Tuscany, wrote towards the Medici personal secretary informing him that the basket of tomatoes sent from your grand duke's Florentine estate at Torre del Gallo "had arrived safely".[citation necessary] Tomatoes were developed predominantly as ornamentals early on soon after their arrival in Italy. By way of example, the Florentine aristocrat Giovanvettorio Soderini wrote how they "were to be sought only for his or her splendor", and ended up developed only in gardens or flower beds. The tomato's power to mutate and develop new and distinct versions served add to its achievement and distribute in the course of Italy. Having said that, even in regions exactly where the local climate supported growing tomatoes, their practice of increasing to the ground advised reduced standing. They were not adopted being a staple in the peasant populace because they were not as filling as other fruits previously readily available. Moreover, each toxic and inedible kinds discouraged Many of us from seeking to eat or put together another versions.[36] In specific regions of Italy, such as Florence, the fruit was utilised exclusively being a tabletop decoration, right up until it had been included in to the area Delicacies from the late 17th or early 18th century.[37] The earliest identified cookbook with tomato recipes was printed in Naples in 1692, nevertheless the author had apparently received these recipes from Spanish resources.[30]:seventeen

Distinctive types ended up developed above the next many hundred years for works by using for example dried tomatoes, sauce tomatoes, pizza tomatoes, and tomatoes for extensive-time period storage. These types are generally known for their put of origin about by a range name. For example,
