MON 809 is an Insect Resistant maize under license from Monsanto. [5] MON 810 is an Insect resistant maize expressing the CryIAc protein for lepidopteran insect pest protection. Under license from Monsanto. [6] MON 832 is an herbicide tolerant maize under license from Monsanto. MON 863 is an Insect Resistant maize under license from Monsanto. [7]
Pesticide application can artificially select for resistant pests. In this diagram, the first generation happens to have an insect with a heightened resistance to a pesticide (red) After pesticide application, its descendants represent a larger proportion of the population, because sensitive pests (white) have been selectively killed.
For cultivation, environmental approval determines whether a crop can be legally grown. Separate approval is generally required to use GM crops in food for human consumption or as animal feed. [2] [3] GM crops were first planted commercially on a large scale in 1996, in the US, China, Argentina, Canada, Australia, and Mexico. [1]
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 ...
In 2013, a second issue being seen across the world, was the development of Bt resistant pests limiting the usefulness of Bt crops. [ 15 ] Main drivers for the widespread resistance in India and China included the high proportion of Bt cotton being planted, 90% and 95% respectively in 2011, [ 9 ] [ 16 ] and few refuge areas.
In 2015, Oxitec developed GM-diamondback moths which produce non-viable female larvae to control populations able to develop resistance to insecticides. The GM-insects were initially placed in cages for field trials. Earlier, the moth was the first crop pest to evolve resistance to DDT [27] and eventually became resistant to 45 other ...
Consequently, the regulatory framework governing the approval of transgenic crops does not apply for Clearfield. [3] As of 2011, herbicide-resistant GM corn was grown in 14 countries. [4] By 2012, 26 varieties of herbicide-resistant GM maize were authorised for import into the European Union, [5] but such imports remain controversial. [6]
RNA silencing-based resistance is a powerful tool for engineering resistant crops. The advantage of RNAi as a novel gene therapy against fungal, viral, and bacterial infection in plants lies in the fact that it regulates gene expression via messenger RNA degradation, translation repression and chromatin remodelling through small non-coding RNAs.
