Lenape (potato)
Lenape (B5141-6) is a potato cultivar first released in 1967 and named after the Lenape Native American tribe, but it had to be pulled from the market in 1970 after findings of its high glycoalkaloid content. It was bred by Wilford Mills of Pennsylvania State University in collaboration with the Wise Potato Chip Company. The Lenape potato was produced by crossing Delta Gold with a wild Peruvian potato (''Solanum chacoense'') known for its resistance to insects. It was selected for its high specific gravity (percentage dry matter) and low sugar content which made it ideal for producing potato chips but it was also immune to potato virus A and resistant to common strains of late blight. It is of medium-late maturity and produces round, white tubers with shallow eyes. Glycoalkaloid content After the Lenape variety was released for commercial production, a potato breeder in Ontario ate some to see if they might be suitable as new potatoes but soon felt nauseated.

Potato
The potato is a starchy food, a tuber of the plant ''Solanum tuberosum'' and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations,University of Wisconsin-Madison, ''Finding rewrites the evolutionary history of the origin of potatoes'' (2005/ref> but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the ''Solanum brevicaule'' complex. Lay summary: In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated. Potatoes were introduced to Europe from the Americas by the Spanish in the second half of the 16 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Genetically Engineered Crops
Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of ''Agrobacterium'' for the delivery of sequences hosted in T-DNA binary vectors. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. Examples in food crops include resistance to certain pests, diseases, environmental conditions, reduction of spoilage, resistance to chemical treatments (e.g. resistance to a herbicide), or improving the nutrient profile of the crop. Examples in non-food crops include production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation. Farmers have widely adopted GM technology. Acreage increased from 1.7 million hectares in 1996 to 185.1 million hectares in 2016, some 12% of global cropland. As of 2016, major crop (soybean, maize, canola a ...

Plant Breeding
Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. It has been used to improve the quality of nutrition in products for humans and animals. The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications. The most frequently addressed agricultural traits are those related to biotic and abiotic stress tolerance, grain or biomass yield, end-use quality characteristics such as taste or the concentrations of specific biological molecules (proteins, sugars, lipids, vitamins, fibers) and ease of processing (harvesting, milling, baking, malting, blending, etc.). Plant breeding can be performed through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to methods that make use of knowledge of genetics and chromosomes, to more complex molecular techniques. Genes in a plant are what determine what type of qualit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chaconine
α-Chaconine is a steroidal glycoalkaloid that occurs in plants of the family Solanaceae. It is a natural toxicant produced in green potatoes and gives the potato a bitter taste. Tubers produce this glycoalkaloid in response to stress, providing the plant with insecticidal and fungicidal properties. It belongs to the chemical family of saponins. Since it causes physiological effects on individual organism, chaconine is considered to be defensive allelochemical. Solanine is a related substance that has similar properties. Symptoms and treatment These are similar to symptoms from ingesting solanine. There are a wide variety of symptoms including: abdominal pain, diarrhea, headache etc. There is no medicine for detoxification but if it is just after consumption, taking laxative or Gastric lavage could be effective. The symptoms could last several days. Toxicity The presence of more than 20 mg/100g tuber glycoalkaloids is toxic for humans. There have been instances of ...

Solanine
Solanine is a glycoalkaloid poison found in species of the nightshade family within the genus ''Solanum'', such as the potato (''Solanum tuberosum''), the tomato (''Solanum lycopersicum''), and the eggplant (''Solanum melongena''). 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 (''Solanum nigrum''), after which it was named. It belongs to the chemical family of saponins. Solanine poisoning Symptoms Solanine poisoning is primarily displayed by gastrointestinal and neurological disorders. Symptoms include nausea, diarrhea, vomiting, stomach cramps, burning of the throat, cardiac dysrhythmia, nightmares, headache, dizziness, itching, eczema, thyroid problems, and inflammation and pain in the joints. In more severe cases, hallucinations, loss of sensation, paralysis, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Glycoalkaloids
Glycoalkaloids are a family of chemical compounds derived from alkaloids to which sugar groups are appended. Several are potentially toxic, most notably the poisons commonly found in the plant species ''Solanum dulcamara'' (bittersweet nightshade) and other plants in the genus ''Solanum'', including potato. A prototypical glycoalkaloid is solanine (composed of the sugar solanose and the alkaloid solanidine), which is found in the potato. The alkaloidal portion of the glycoalkaloid is also generically referred to as an aglycone. The intact glycoalkaloid is poorly absorbed from the gastrointestinal tract but causes gastrointestinal irritation. The aglycone is absorbed and is believed to be responsible for observed nervous system signs. Glycoalkaloids are typically bitter tasting, and produce a burning irritation in the back of the mouth and side of the tongue. The Aymara people of Bolivia use taste to detect the levels of glycoalkaloids in potatoes to determine the safety of vario ...

Late Blight
''Phytophthora infestans'' is an oomycete or water mold, a fungus-like 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 1845–1852 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 in water-saturated or nearly saturated environments, and zoospore production is favored at temperatures below . Lesion growth rates are typically optimal at a slightly warmer temperature range of . Etymology The genus name ''Phytophthora'' comes from the Greek –(), meaning : "plant" – plus the Greek (), meaning : "decay, ruin, perish". The species name ''infestans'' is the present participle of the Latin verb , meaning : "attacking, destroying", from which we ...

Potato Chip
A potato chip (North American English; often just chip) or crisp (British and Irish English) is a thin slice of potato that has been either deep fried, baked, or air fried until crunchy. They are commonly served as a snack, side dish, or appetizer. The basic chips are cooked and salted; additional varieties are manufactured using various flavorings and ingredients including herbs, spices, cheeses, other natural flavors, artificial flavors, and additives. Potato chips form a large part of the snack food and convenience food market in Western countries. The global potato chip market generated total revenue of US$16.49 billion in 2005. This accounted for 35.5% of the total savory snacks market in that year ($46.1 billion). History The earliest known recipe for something similar to today's potato chips is in William Kitchiner's book '' The Cook's Oracle'' published in 1817, which was a bestseller in the United Kingdom and the United States. The 1822 edition's recipe for "Pota ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
