  • strains
  • In most strains of B. thuringiensis, the cry genes are located on a plasmid (cry is not a chromosomal gene in most strains). (wikipedia.org)
  • New strains of Bt are developed and introduced over time as insects develop resistance to Bt, or the desire occurs to force mutations to modify organism characteristics or to use homologous recombinant genetic engineering to improve crystal size and increase pesticidal activity or broaden the host range of Bt and obtain more effective formulations. (wikipedia.org)
  • Iran
  • In 1986, Moazami managed a joint project of the Iranian Research Organisation for Science and Technology (IROST) with UNDP and UNESCO, evaluated "the feasibility of producing and using Bacillus thiringiensis to control malaria vectors in southern Iran. (wikipedia.org)
  • group
  • In 2000, a novel functional group of Cry protein, designated parasporin, was discovered from noninsecticidal B. thuringiensis isolates. (wikipedia.org)
  • vectors
  • In 1986, Moazami managed a joint project of the Iranian Research Organisation for Science and Technology (IROST) with UNDP and UNESCO, evaluated "the feasibility of producing and using Bacillus thiringiensis to control malaria vectors in southern Iran. (wikipedia.org)
  • pests
  • Though Bt based agricultural formulations are being used since many decades, the arrival of genetically modified (GM) Bt seeds and crops heralded a new beginning in agriculture because of efficient control of the pests that increased the yield of the crops and at the same time reduced the use of synthetic and harmful chemical pesticides.
