The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Eggplant (US), aubergine (UK), or brinjal is a plant species in the nightshade family Solanaceae, Solanum melongena, grown for its often purple edible fruit.
Solanum is a large and diverse genus of flowering plants, which include three food crops of high economic importance, the potato, the tomato and the eggplant. It also contains the nightshades and horse nettles, as well as numerous plants cultivated for their ornamental flowers and fruit.
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. 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.
Solanum carolinense, the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States that has spread widely throughout much of temperate North America. It has also been found in parts of Europe, Asia, and Australia. The stem and undersides of larger leaf veins are covered with spines.
Solanine is a glycoalkaloid poison found in species of the nightshade family within the genus Solanum, such as the potato, the tomato, and the eggplant. It can occur naturally in any part of the plant, including the leaves, fruit, and tubers. Solanine has pesticidal properties, and it is one of the plant's natural defenses. Solanine was first isolated in 1820 from the berries of the European black nightshade, after which it was named. It belongs to the chemical family of saponins.
Lycopersicon was a genus in the flowering plant family Solanaceae. It contained about 13 species in the tomato group of nightshades. First removed from the genus Solanum by Philip Miller in 1754, its removal leaves the latter genus paraphyletic, so modern botanists generally accept the names in Solanum. The name Lycopersicon is still used by gardeners, farmers, and seed companies. Collectively, the species in this group apart from the common cultivated plant are called wild tomatoes.
The term bush tomato refers to the fruit or entire plants of certain nightshade (Solanum) species native to the more arid parts of Australia. While they are quite closely related to tomatoes, they might be even closer relatives of the eggplant, which they resemble in many details. There are 94 natives and 31 introduced species in Australia.
Solanum pimpinellifolium, commonly known as the currant tomato, is a wild species of tomato native to Ecuador and Peru but naturalized elsewhere, such as the Galápagos Islands. Its small fruits are edible, and it is commonly grown in gardens as an heirloom tomato, although it is considered to be wild rather than domesticated as is the commonly cultivated tomato species Solanum lycopersicum. Its genome was recently sequenced.
Solanum ellipticum is known as potato bush and under the more ambiguous name of "bush tomato". The Arrernte name of merne awele-awele might refer to this species, and/or to the similar S. quadriloculatum. Native to Australia, the potato bush is a small fruiting shrub in the Solanaceae family.
The tomato is the edible, often red, berry of the nightshade Solanum lycopersicum, commonly known as a tomato plant. The species originated in western South America. The Nahuatl word tomatl gave rise to the Spanish word tomate, from which the English word tomato derived. Its use as a cultivated food may have originated with the indigenous peoples of Mexico. The Spanish encountered the tomato from their contact with the Aztec during the Spanish colonization of the Americas and brought it to Europe. From there, the tomato was introduced to other parts of the European-colonized world during the 16th century.
Puccinia pittieriana is a species of rust fungus. It is a plant pathogen which infects agricultural crops such as potato and tomato. Its common names include common potato rust and common potato and tomato rust.
Solanum lanceolatum, with the common names orangeberry nightshade and lanceleaf nightshade, is a species of nightshade. It is native to regions of South America, including the Cerrado ecoregion of the Tropical and subtropical grasslands, savannas, and shrublands biome, primarily in Brazil.
Solanum jamesii is a species of nightshade. Its range includes the southern United States. All parts of the plant, and especially the fruit, are toxic, containing solanine when it matures. The tubers were/are eaten raw or cooked by several Native American tribes, but they require leaching and boiling in clay in order to be rendered edible. The tubers are also extremely small when compared to familiar varieties of S. tuberosum. Escalante Valley in Utah boasts the oldest known cultivation sites of the Four Corners potato, dating back over 7,000 years, and the plant is so prevalent there that a former name for area was "Potato Valley". S. jamesii is sometimes grown in yards or gardens as an ornamental plant, and there have been recent experiments in Escalante, Utah to start growing it as a food vegetable again.
Solanum rostratum is a species of nightshade that is native to the United States and northern and central Mexico. Common names include buffalobur nightshade, buffalo-bur, spiny nightshade, Colorado bur, Kansas thistle, Mexican thistle, and Texas thistle.
Solanum erianthum is a species of nightshade that is native to southern North America and northern South America. It has been introduced to other parts of the world and has a nearly pantropical distribution. Common names include potatotree, mullein nightshade, velvet nightshade, and salvadora. The potatoes are not the fruits of the trees, they are the leaves.
Lebia grandis is a ground beetle in the family Carabidae found in North America. It is a specialist predator on the eggs and larvae of Colorado potato beetles, and its larvae are obligate parasitoids of Colorado potato beetle pupae.
Solanum chacoense is a species of wild potato. It is native to South America, where it can be found in Brazil, Bolivia, Argentina, Peru, Uruguay, and Paraguay. It "is one of the most widely distributed wild potato species." It grows as a common weed in disturbed habitat such as crop fields. It can also be found in Australia, China, the United States, England, New Zealand, and elsewhere as an introduced species.
The Solanaceae, or nightshades, are an economically important family of flowering plants. The family ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of important agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers, and tobacco—are widely used. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Trichobaris trinotata, commonly known as the "potato stalk borer", is a species of weevil in the family Curculionidae. It is found in North America where it is a pest of potato plants, the larvae tunnelling inside their stems.
