MON 863: Difference between revisions

'''MON 863''' is a [[Genetically modified maize|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]]''.<ref name='Greenpeace MON863 chronicle'>{{cite web | url = http://www.greenpeace.org/international/Global/international/planet-2/report/2007/3/mon863_chronicle_of_deception.pdf | title = The MON863 case - a chronicle of systematic deception | access-date = 2010-07-22 | format = PDF | publisher = [[Greenpeace]] | quote = MON863 is a genetically modified corn that expresses a Bt-toxin. This toxin is a modified version of the delta endotoxin Cry3Bb1 which originates from the microorganism Bacillus thuringiensis. The genetic manipulation is aimed at protecting maize plants against a pest called corn rootworm (Diabrotica spp.). MON863 differs from other Bt-corns already placed on the market (MON810, BT11, Bt176), which produce a modified Cry1Ab toxin conferring resistance to a pest called European corn borer (Ostrinia nubilalis), in that it produces an artificial Cry3Bb1 toxin. In addition to the modified Cry3Bb1 toxin gene MON863 contains an antibiotic resistance marker gene.}}</ref><ref name='Doull 2007 genetics'>{{cite journal |doi=10.1016/j.fct.2007.08.033 |title=Report of an Expert Panel on the reanalysis by of a 90-day study conducted by Monsanto in support of the safety of a genetically modified corn variety (MON 863) |year=2007 |last1=Doull |first1=J. |last2=Gaylor |first2=D. |last3=Greim |first3=H.A. |last4=Lovell |first4=D.P. |last5=Lynch |first5=B. |last6=Munro |first6=I.C. |journal=[[Food and Chemical Toxicology]] |volume=45 |issue=11 |pages=2073–85 |pmid=17900781}}</ref> This protects the plant from [[Diabrotica|corn rootworm]].<ref name='Doull 2007 genetics' /><ref name='Coghlan 2010-01-22'>{{cite news | first = Andy | last = Coghlan | title = Engineered maize toxicity claims roundly rebuffed | date = 2010-01-22 | url = https://www.newscientist.com/article/mg20527444.000-engineered-maize-toxicity-claims-roundly-rebuffed.html | work = New Scientist | access-date = 2010-07-21}}</ref> 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]].<ref name='Greenpeace MON863 chronicle' /><ref name='Lorch 2005-09-30'>{{cite web | url = http://www.ifrik.org/files-ifrik/0509_greenpeace_mon863_hybrids.pdf | title = EFSA’sEFSA's Opinion on MON863 hybrids | access-date = 2010-07-22 | last = Lorch | first = Antje | date = 2005-09-30 | format = PDF | work = ifrik | publisher = [[Greenpeace]] | quote = MON863 contains an GM antibiotic resistance gene (nptII) against kanamycin and neomycin. | url-status = dead | archive-url = https://web.archive.org/web/20110726171634/http://www.ifrik.org/files-ifrik/0509_greenpeace_mon863_hybrids.pdf | archive-date = 2011-07-26 }}</ref>
