Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

MON 863
MON 863 is a genetically engineered variety of maize produced by Monsanto. It is genetically altered to express a modified version of Cry3Bb1, a delta endotoxin which originates from ''Bacillus thuringiensis''. This protects the plant from corn rootworm. Unlike MON 810, Bt 11, and Bt 176 which each produce a modified Cry1Ab, MON 863 instead produces a modified Cry3Bb1 toxin and contains nptII, a marker gene for antibiotic resistance. History In 2004, Monsanto sought approval in Europe to introduce MON 863. Approval was granted in 2005 for use in feed and in 2006 for use in food. There was controversy over acceptance by regulatory bodies of industry-funded toxicity studies and over the design of those studies led by Pr Gilles-Éric Séralini, who was on the committee that reviewed MON863 for the French government. See Genetically modified food controversies for details of this controversy, which extended beyond MON 863. Following legal action by parties including the Swedish ...

Cry34Ab1
Cry34Ab1 is one member of a binary ''Bacillus thuringiensis'' (Bt) crystal protein set isolated from Bt strain PS149B1. The protein exists as a 14 kDa aegerolysin that, in presence of Cry35Ab1, exhibits insecticidal activity towards Western Corn Rootworm. The protein has been transformed into maize plants under the commercialized events 4114 (DP-ØØ4114-3) by Pioneer Hi-Bred and 59122 (DAS-59122-7) by Dow AgroSciences. These events have, in turn, been bred into multiple trait stacks in additional products. Cry34/35Ab1 binary toxins bind to the insect's brush border membrane vesicles (BBMVs) of cells in the epithelial lining of midgut, where they form pores; this leads to necrosis and, eventually, the insect's death. The Cry35Ab1 (45 kDa) protein does not convey specificity in the absence of Cry34Ab1, indicating that the smaller 14 kDa Cry34Ab1 protein is critical for BBMV binding and recruitment of Cry35Ab1 to induce insecticidal effect. Cry34Ab1 is unrelated to Bt delta-endo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycogen Seeds
Mycogen Seeds, headquartered in Indianapolis, Indiana, United States, provides seeds for agriculture. Mycogen produces, markets and sells hybrid seed corn. The company also markets and sells sorghum, sunflower, soybean, alfalfa, and canola. The Mycogen Corporation was formed in 1982 by members of the San Diego business and scientific communities, including David H. Rammler, a partner in the venture capital firm of Vanguard Associates, who served as the first chairman of the company, and Andrew C. Barnes, a biochemist with an MBA from the Stanford School of Business. The original concept was to develop environmentally safe herbicides from fungi using genetic engineering, thus the name Mycogen, coined from the Greek words for fungus and genetics. In 1998, the company was acquired by Dow Chemical Company. It then became a subsidiary of Corteva Agriscience Corteva, Inc. (also known as Corteva Agriscience) is a major American agricultural chemical and seed company that was th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DuPont Pioneer
Pioneer Hi-Bred International, Inc. is a U.S.-based producer of seeds for agriculture. They are a major producer of genetically modified organisms (GMOs), including genetically modified crops with insect and herbicide resistance.

Wallace, along with a group of Des Moines, Iowa businessmen, founded the Hi-Bred Corn Company. Wallace had been experimenting with hybridization of corn and became convinced that hybrid seed corn would become important.

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cry1F
Delta endotoxins (δ-endotoxins) are pore-forming toxins produced by ''Bacillus thuringiensis'' species of bacteria. They are useful for their insecticidal action and are the primary toxin produced by Bt maize/corn. During spore formation the bacteria produce crystals of such proteins (hence the name Cry toxins) that are also known as parasporal bodies, next to the endospores; as a result some members are known as a parasporin. The Cyt (cytolytic) toxin group is a group of delta-endotoxins different from the Cry group. Mechanism of action When an insect ingests these proteins, they are activated by proteolytic cleavage. The N-terminus is cleaved in all of the proteins and a C-terminal extension is cleaved in some members. Once activated, the endotoxin binds to the gut epithelium and causes cell lysis by the formation of cation-selective channels, which leads to death. For many years there was no clarity as to the relationship between aminopeptidase N and Bt toxins. Althou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imidazolinone
Imidazolidinones or imidazolinones are a class of 5-membered ring heterocycles structurally related to imidazole. Imidazolidinones feature a saturated C3N2 nucleus, except for the presence of a urea or amide functional group in the 2 or 4 positions. 2-Imidazolidinones The 2-imidazolidinones are cyclic derivatives of urea. 1,3-Dimethyl-2-imidazolidinone is a polar solvent and Lewis base. Drugs featuring this ring system include emicerfont, imidapril, and azlocillin. Dimethylol ethylene urea is the reagent used in permanent press clothing. 4-Imidazolidinones 4-Imidazolidinones can be prepared from phenylalanine in two chemical steps (amidation with methylamine followed by condensation reaction with acetone): Imidazolidinone catalyst work by forming an iminium ion with carbonyl groups of α,β-unsaturated aldehydes ( enals) and enones in a rapid chemical equilibrium. This iminium activation lower the substrate's LUMO. Several 4-imidazolidinones have been investigated. Dru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
