LMO name
WideStrike™ cotton
Transformation event
281-24-236 x 3006-210-23 (MXB-13)
Unique identifier
DAS-24236-5 x DAS-21Ø23-5
Developer(s)
Description
A stacked lepidopteran insect-resistant cotton derived from conventional cross-breeding of DAS-24236-5 and DAS-21Ø23-5, with insect resistance conferred by the cry1F gene from the common soil bacterium Bacillus thuringiensis var. aizawai and the cry1Ac gene from B. thuringiensis var. kurstaki.
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Notes regarding the genetic elements introduced or modified in this LMO
DNA insert from 3006-210-23 vector pMYC3006:
Lepidopteran-resistant cotton, with insect resistance conferred by the cry1Ac gene from the common soil bacterium Bacillus thuringiensis (Bt) var. kurstaki strain HD73. Coding sequences of Cry1A(c) and pat genes altered for optimal expression in plant cells.

DNA insert from 281-24-236 vector pAGM281:
Lepidopteran-resistant cotton, with insect resistance conferred by the cry1F gene from the common soil bacterium Bacillus thuringiensis (Bt) var. aizawai. Coding sequences of Cry1F and pat genes altered for optimal expression in plant cells.

For additional information on this LMO, please refer to the records of the parental LMOs.

Additional Information
Additional Information
Cry proteins act by selectively binding to specific sites localized on the lining of the midgut of susceptible insect species. Following binding, pores are formed that disrupt midgut ion flow, causing gut paralysis and eventual death due to bacterial sepsis. There are no binding sites for delta-endotoxins of B. thuringiensis on the surface of mammalian intestinal cells, therefore, livestock animals and humans are not susceptible to these proteins.
