Cry1Ac
Cry1Ac protoxin is a crystal protein produced by the bacterium'' Bacillus thuringiensis'' (Bt) during sporulation. Cry1Ac is one of the delta endotoxins produced by this bacterium which act as insecticides. Because of this, the genes for these have been introduced into commercially important crops by genetic engineering (e.g. cotton and tomato by Monsanto) in order to confer pest resistance on those plants.〔〔〔 Transgenic Bt cotton initially expressed a single Bt gene, which codes for Cry1Ac.〔 Subsequently, Bt cotton has added other delta endotoxins.〔 Products such as Bt cotton, Bt brinjal and genetically modified maize have received attention due to a number of issues, including genetically modified food controversies,〔〔''Pests could overcome GM cotton toxins: Caterpillars reveal a chink in the armour of transgenic crops''. Heidi Ledford ()〕〔 and the Séralini affair.〔〔''Profile of Gilles-Éric Séralini, Author Of Republished Retracted GMO Corn Rat Study''. http://www.forbes.com/sites/jonentine/2014/06/24/profile-of-gilles-eric-seralini-author-of-republished-retracted-gmo-corn-rat-study/〕 Cry1Ac is a mucosal adjuvant (an immune-response enhancer).〔〔〔 It has been used in research to develop a vaccine against the amoeba ''Naegleria fowleri''.〔 This amoeba can invade and attack the human nervous system and brain, causing primary amoebic meningoencephalitis, which is nearly always fatal. ==See also== Genetically modified organism
