The tomato will be the edible berry of your plant Solanum lycopersicum, generally called a tomato plant. The species originated in western South The usa and Central The us.[2][3] The Nahuatl (the language used by the Aztecs) word tomatl gave increase to your Spanish word tomate, from which the English term tomato derived.[3][4] Its domestication and use like a cultivated foodstuff could have originated Along with the indigenous peoples of Mexico.[2][5] The Aztecs utilized tomatoes inside their cooking at some time of your Spanish conquest on the Aztec Empire, and after the Spanish encountered the tomato for the first time immediately after their contact with the Aztecs, they introduced the plant to Europe. From there, the tomato was launched to other portions of the ecu-colonized earth in the 16th century.[2]
Tomatoes are a big source of umami flavor.[six] The tomato is consumed in various techniques, Uncooked or cooked, in several dishes, sauces, salads, and beverages. Whilst tomatoes are fruits—botanically categorised as berries—they are generally utilized for a vegetable ingredient or facet dish.[three]
Quite a few sorts of the tomato plant are greatly grown in temperate climates the world over, with greenhouses allowing to the production of tomatoes throughout all seasons of the yr. Tomato crops normally develop to 1–3 meters (three–10 ft) in top. They can be vines which have a weak stem that sprawls and normally demands aid.[two] Indeterminate tomato vegetation are perennials in their native habitat, but are cultivated as annuals. (Determinate, or bush, vegetation are annuals that cease escalating at a certain height and produce a crop unexpectedly.) The dimensions on the tomato differs according to the cultivar, with A variety of 1–10 cm (1/2–four in) in width.[two]

Etymology
The phrase tomato originates from the Spanish tomate, which consequently originates from the Nahuatl term tomatl ['tomat??], meaning 'the swelling fruit'.[four] The indigenous Mexican tomatillo is tomate (Nahuatl: tomatl About this soundpronunciation (support·facts), that means 'Unwanted fat drinking water' or 'Body fat factor').[seven] When Aztecs started to cultivate the fruit being much larger, sweeter and crimson, they called the new selection xitomatl (or jitomates) (pronounced [?i?'tomat?]),[two] ('plump with navel' or 'Excess fat drinking water with navel'). The scientific species name lycopersicum (from your 1753 e-book, Species Plantarum) is of Greek origin (????pe?s????; lykopersikon), meaning 'wolf peach'.
Pronunciation
The standard pronunciations of tomato are /t?'me?to?/ (usual in American English) and /t?'m??to?/ (common in British English).[8] The word's twin pronunciations have been immortalized in Ira and George Gershwin's 1937 music "Let's Contact The full Matter Off" ("You like /p?'te?to?/ and I like /p?'t??to?/ / You prefer /t?'me?to?/ And that i like /t?'m??to?/") and became a image for nitpicking pronunciation disputes.[citation desired] Within this potential, it's got even turn out to be an American and British slang time period: saying "/t?'me?to? t?'m??to?/" when presented with two choices can mean "What is actually the main difference?" or "It is really all the identical to me".[citation necessary]

Tomatoes are viewed as a fruit or vegetable according to context. In accordance with Encyclopedia Britannica, tomatoes are a fruit labeled in grocery shops for a vegetable as a consequence of (the flavor) and nutritional purposes.[three]
Tomatoes basic and sliced
Botanically, a tomato can be a fruit—a berry, consisting of your ovary, along with its seeds, of a flowering plant. Nevertheless, the tomato is considered a "culinary vegetable" since it features a Considerably lessen sugar material than culinary fruits; it is typically served as A part of a salad or major class of the food, in lieu of like a dessert. Tomatoes are usually http://thinktomato.com not the only food stuff supply using this ambiguity; bell peppers, cucumbers, eco-friendly beans, eggplants, avocados, and squashes of all kinds (like zucchini and pumpkins) are all botanically fruit, still cooked as veggies. This has led to legal dispute in the United States. In 1887, U.S. tariff rules that imposed a duty on vegetables, but not on fruit, brought on the tomato's status to be a make a difference of lawful relevance. In Nix v. Hedden, the U.S. Supreme Courtroom settled the tariff controversy on May possibly 10, 1893, by declaring the tomato is really a vegetable, determined by the popular definition that classifies greens by use—They're generally served with evening meal and not dessert.[9] The Keeping of this case applies only into the interpretation of the Tariff of 1883, and the courtroom didn't purport to reclassify the tomato for botanical or other needs.
Botany
Description
Tomato flower
An unripe tomato escalating on the vine
Tomato vegetation are vines, in the beginning decumbent, normally increasing one hundred eighty cm (6 ft) or maybe more over the ground if supported, Though erect bush types are bred, typically 100 cm (three ft three in) tall or shorter. Indeterminate varieties are "tender" perennials, dying every year in temperate climates (These are originally indigenous to tropical highlands), Despite the fact that they will Dwell up to 3 many years inside a greenhouse sometimes. Determinate types are annual in all climates.[citation desired]
Tomato plants are dicots, and improve as being a number of branching stems, having a terminal bud at the idea that does the actual rising. When that tip at some point stops escalating, whether as a result of pruning or flowering, lateral buds just take in excess of and mature into other, completely practical, vines.[10]
Tomato vines are typically pubescent, indicating protected with wonderful shorter hairs. These hairs facilitate the vining system, turning into roots where ever the plant is in contact with the ground and moisture, especially if the vine's relationship to its first root continues to be damaged or severed.[citation needed]
Most tomato plants have compound leaves, and so are named standard leaf (RL) plants, but some cultivars have simple leaves often called potato leaf (PL) style on account of their resemblance to that individual relative. Of RL plants, there are versions, including rugose leaves, that are deeply grooved, and variegated, angora leaves, that have additional shades exactly where a genetic mutation results in chlorophyll to get excluded from some parts of the leaves.[11]
The leaves are 10–25 cm (four–ten in) extended, odd pinnate, with five to nine leaflets on petioles,[12] Every single leaflet around eight cm (three in) very long, that has a serrated margin; both the stem and leaves are densely glandular-hairy.[citation wanted]
Their bouquets, showing within the apical meristem, hold the anthers fused together the perimeters, forming a column encompassing the pistil's design and style. Bouquets in domestic cultivars may be self-fertilizing. The bouquets are one–two cm (1/two–3/4 in) throughout, yellow, with five pointed lobes over the corolla; They can be borne inside of a cyme of a few to twelve with each other.[citation needed]
Despite the fact that in culinary terms, tomato is considered a vegetable, its fruit is classed botanically as a berry.[13] As a real fruit, it develops through the ovary of the plant following fertilization, its flesh comprising the pericarp partitions. The fruit is made up of hollow spaces packed with seeds and dampness, named locular cavities. These vary, among cultivated species, Based on form. Some smaller types have two cavities, world-formed types usually have three to five, beefsteak tomatoes have a great range of scaled-down cavities, when paste tomatoes have very few, incredibly small cavities.[fourteen][15][16]
For propagation, the seeds need to come from a mature fruit, and be dried or fermented right before germination.[citation required]
Classification
In 1753, Linnaeus positioned the tomato during the genus Solanum (alongside the potato) as Solanum lycopersicum. In 1768, Philip Miller moved it to its have genus, naming it Lycopersicon esculentum.[17] This identify arrived into extensive use, but was technically in breach from the plant naming policies for the reason that Linnaeus's species name lycopersicum still experienced priority. Even though the name Lycopersicum lycopersicum was proposed by Karsten (1888), this is simply not utilized since it violates the Intercontinental Code of Nomenclature[18] barring the usage of tautonyms in botanical nomenclature. The corrected title Lycopersicon lycopersicum (Nicolson 1974) was technically valid, because Miller's genus identify and Linnaeus's species identify vary in specific spelling, but due to the fact Lycopersicon esculentum is becoming so renowned, it was formally mentioned as being a nomen conservandum in 1983, and might be the correct identify for your tomato in classifications which tend not to area the tomato from the genus Solanum.
Genetic proof has now proven that Linnaeus was appropriate to put the tomato within the genus Solanum, creating Solanum lycopersicum the right identify.[one][19] Both of those names, on the other hand, will probably be located in the literature for a while. Two of the main motives for contemplating the genera individual would be the leaf composition (tomato leaves are markedly various from some other Solanum), as well as the biochemistry (a lot of the alkaloids widespread to other Solanum species are conspicuously absent during the tomato). Conversely, hybrids of tomato and diploid potato is usually produced inside the lab by somatic fusion, and are partially fertile,[twenty] giving proof on the shut partnership involving these species.
Genetic modification
Key post: Genetically modified tomato
Tomatoes that were modified applying genetic engineering are produced, and although none are commercially accessible now, they are previously. The primary commercially readily available genetically modified food items was many different tomato named the Flavr Savr, which was engineered to possess a more time shelf lifestyle.[21] Experts are continuing to produce tomatoes with new features not present in organic crops, including enhanced resistance to pests or environmental stresses. Other tasks purpose to complement tomatoes with substances which could give health and fitness Added benefits or present improved nourishment.
A global consortium of scientists from 10 international locations, between them researchers from your Boyce Thompson Institute for Plant Investigation, began sequencing the tomato genome in 2004, which is developing a databases of genomic sequences and data to the tomato and related plants.[22][23] A prerelease Edition on the genome was produced obtainable in December 2009.[24] The genomes of its mitochondria and chloroplasts may also be getting sequenced as Element of the undertaking. The entire genome for the cultivar Heinz 1706 was released on 31 May possibly 2012 in Nature.[twenty five] Considering that all kinds of other fruits, like strawberries, apples, melons, and bananas share a similar properties and genes, scientists stated the published genome could support to enhance meals top quality, food items security and lower expenditures of every one of these fruits.[26]

The Tomato Genetic Resource Middle, Germplasm Resources Information and facts Community, AVRDC, and diverse seed banking companies around the world store seed symbolizing genetic versions of value to modern agriculture. These seed shares are available for legitimate breeding and investigation endeavours. When unique breeding efforts can make useful final results, the bulk of tomato breeding operate is at universities and key agriculture-similar companies. These efforts have resulted in important regionally tailored breeding traces and hybrids, like the Mountain sequence from North Carolina. Businesses which include Heinz, Monsanto, BHNSeed, and Bejoseed have breeding courses that attempt to strengthen production, dimension, form, color, taste, condition tolerance, pest tolerance, nutritional worth, and various other features.[citation essential]
Historical past
Solanum lycopersicum var. lycopersicum: the oldest surviving tomato fruit and leaves. Web page from the En Tibi Herbarium, 1558. Naturalis Leiden.
The wild ancestor with the tomato is indigenous to western South The us.[27] These wild versions ended up the dimensions of peas.[27] Aztecs and other peoples in Mesoamerica were the main to acquire domesticated the fruit and used in their cooking. The Spanish initially launched tomatoes to Europe, the place they became Utilized in Spanish foods. In France, Italy and northern Europe, the tomato was to begin with developed being an ornamental plant. It absolutely was regarded with suspicion for a food stuff for the reason that botanists identified it as a nightshade, a relative from the toxic belladonna.[3] This was exacerbated because of the conversation in the tomato's acidic juice with pewter plates.[28] The leaves and immature fruit is made up of tomatine, which in significant portions can be poisonous. However, the ripe fruit includes no tomatine.[29]
Mesoamerica
The exact day of domestication is unidentified; by five hundred BC, it had been now being cultivated in southern Mexico and doubtless other parts.[30]:13 The Pueblo individuals are considered to get believed that individuals that witnessed the ingestion of tomato seeds were being blessed with powers of divination.[31] The massive, lumpy selection of tomato, a mutation from the smoother, more compact fruit, originated in Mesoamerica, and would be the direct ancestor of some modern-day cultivated tomatoes.[thirty]:fifteen
The Aztecs lifted a number of forms of tomato, with pink tomatoes identified as xictomatl and green tomatoes referred to as tomatl (Tomatillo).[32] Based on Bernardino de Sahagún he noticed a great assortment of tomatoes within the Aztec industry at Tenochtitlán (Mexico City): “. . . massive tomatoes, little tomatoes, leaf tomatoes, sweet tomatoes, massive serpent tomatoes, nipple-shaped tomatoes,” and tomatoes of all shades through the brightest pink into the deepest yellow.[33] Bernardino de Sahagún pointed out Aztecs cooking many sauces, some with and devoid of tomatoes of various dimensions, serving them in city marketplaces: "foods sauces, sizzling sauces; fried [foodstuff], olla-cooked [foods], juices, sauces of juices, shredded [foodstuff] with chile, with squash seeds [most likely Cucurbita pepo], with tomatoes, with smoked chile, with hot chile, with yellow chile, with moderate red chile sauce, yellow chile sauce, warm chile sauce, with "hen excrement" sauce, sauce of smoked chile, heated [sauces], bean sauce; [he sells] toasted beans, cooked beans, mushroom sauce, sauce of little squash, sauce of huge tomatoes, sauce of regular tomatoes, sauce of assorted styles of sour herbs, avocado sauce."[34]
Spanish distribution
Spanish conquistador Hernán Cortés may well are already the very first to transfer a small yellow tomato to Europe after he captured the Aztec city of Tenochtitlan, now Mexico Town, in 1521. The earliest discussion in the tomato in European literature appeared in a very herbal penned in 1544 by Pietro Andrea Mattioli, an Italian medical professional and botanist, who instructed that a completely new variety of eggplant had been brought to Italy that was blood red or golden shade when mature and will be divided into segments and eaten like an eggplant—that's, cooked and seasoned with salt, black pepper, and oil. It was not until eventually ten several years later on that tomatoes have been named in print by Mattioli as pomi d'oro, or "golden apples".[thirty]:13
After the Spanish colonization in the Americas, the Spanish dispersed the tomato throughout their colonies in the Caribbean. In addition they took it to your Philippines, from wherever it spread to southeast Asia and afterwards the complete Asian continent. The Spanish also brought the tomato to Europe. It grew effortlessly in Mediterranean climates, and cultivation began within the 1540s. It was likely eaten Soon after it had been introduced, and was absolutely being used as food from the early 17th century in Spain.
China
The tomato was introduced to China, very likely by using the Philippines or Macau, while in the 1500s. It was presented the title fanqié (barbarian eggplant), since the Chinese named lots of foodstuffs introduced from abroad, but referring precisely to early introductions.[35]
Italy
The recorded record of tomatoes in Italy dates back again to at the least 31 Oct 1548, when your house steward of Cosimo de' Medici, the grand duke of Tuscany, wrote to your Medici non-public secretary informing him that the basket of tomatoes sent within the grand duke's Florentine estate at Torre del Gallo "experienced arrived properly".[citation essential] Tomatoes ended up grown mostly as ornamentals early on following their arrival in Italy. For instance, the Florentine aristocrat Giovanvettorio Soderini wrote how they "were being sought only for his or her natural beauty", and have been grown only in gardens or flower beds. The tomato's power to mutate and generate new and distinct versions aided add to its achievement and distribute all through Italy. However, even in spots the place the local climate supported developing tomatoes, their practice of increasing to the ground prompt low status. They weren't adopted to be a staple of the peasant populace because they were not as filling as other fruits currently offered. Additionally, each toxic and inedible versions discouraged many people from trying to take in or put together every other varieties.[36] In specified regions of Italy, for instance Florence, the fruit was utilised only being a tabletop decoration, until eventually it absolutely was integrated in the regional cuisine while in the late seventeenth or early 18th century.[37] The earliest learned cookbook with tomato recipes was published in Naples in 1692, although the creator experienced apparently attained these recipes from Spanish sources.[30]:seventeen

Exceptional varieties were being developed above the following various hundred a long time for makes use of such as dried tomatoes, sauce tomatoes, pizza tomatoes, and tomatoes for extended-expression storage. These kinds are often recognized for their spot of origin up to by a variety identify. As an example, Pomodorino del Piennolo del Vesuvio is definitely the "hanging tomato of Vesuvius" or maybe the Pomodoro di Pachino
