  2. Bacillus thuringiensis - Wikipedia

    en.wikipedia.org/wiki/Bacillus_thuringiensis

    Bacillus thuringiensis (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies , as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, flour mills and ...

  3. Cry1Ac - Wikipedia

    en.wikipedia.org/wiki/Cry1Ac

    Cry1Ac protoxin is a crystal protein produced by the gram-positive bacterium, Bacillus thuringiensis (Bt) during sporulation.Cry1Ac is one of the delta endotoxins produced by this bacterium which act as insecticides.

  4. Delta endotoxins - Wikipedia

    en.wikipedia.org/wiki/Delta_endotoxins

    Delta endotoxins (δ-endotoxins) are a family of pore-forming toxins produced by Bacillus thuringiensis species of bacteria. They are useful for their insecticidal action and are the primary toxin produced by the genetically modified (GM) Bt maize/corn and other GM crops.

  5. Cry6Aa - Wikipedia

    en.wikipedia.org/wiki/Cry6Aa

    Cry6Aa (Pesticidal crystal protein Cry6Aa) is a toxic crystal protein generated by the bacterial family Bacillus thuringiensis during sporulation. [1] This protein is a member of the alpha pore forming toxins family, which gives it insecticidal qualities advantageous in agricultural pest control.

  6. Cry34Ab1 - Wikipedia

    en.wikipedia.org/wiki/Cry34Ab1

    Cry34Ab1 is one member of a binary Bacillus thuringiensis (Bt) crystal protein set isolated from Bt strain PS149B1. [1] The protein exists as a 14 kDa aegerolysin that, in presence of Cry35Ab1, exhibits insecticidal activity towards Western Corn Rootworm.

  7. Genetically modified brinjal - Wikipedia

    en.wikipedia.org/wiki/Genetically_modified_brinjal

    The genetically modified brinjal is a suite of transgenic brinjals (also known as eggplant or aubergine) created by inserting a crystal protein gene from the soil bacterium Bacillus thuringiensis into the genome of various brinjal cultivars.

  8. Bt cotton - Wikipedia

    en.wikipedia.org/wiki/Bt_cotton

    Strains of the bacterium Bacillus thuringiensis produce over 200 different Bt toxins, each harmful to different insects.Most notably, Bt toxins are insecticidal to the larvae of moths and butterflies, beetles, cotton bollworms and flies but are harmless to other forms of life. [1]

  9. Pore-forming toxin - Wikipedia

    en.wikipedia.org/wiki/Pore-forming_toxin

    These include the Cry23/Cry37 toxin from Bacillus thuringiensis. [28] These toxins have some structural similarity to the Cry34/Cry35 binary toxin but neither component shows a match to established Pfam families and the features of the larger Cry23 protein have more in common with the Etx/Mtx2 family than the Toxin_10 family to which Cry35 belongs.
