LMO name
Cotton modified for insect resistance
Transformation event
Unique identifier
Dr Satish Raina
Global Transgenes Ltd (Nath Group Company)
Nath House, Nath Road, Aurangabad - 431005
This modified cotton contains the insecticidal cry1Ab/Ac gene which imparts resistance against Lepidoptera.

NOTE: This LMO was formerly referred to with the UID GTL-GFM311-7.
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.
Gossypium hirsutum - Cotton
Characteristics of the transformation process
pGBI4AB derived from pBI121
Techniques used for the modification
  • Pollen Tube Pathway method (Chinese Patent)
Introduced or modified genetic elements
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
Cry1Ab/Ac - Bacillus thuringiensis - Bt, Bacillus, BACTU
Resistance to diseases and pests - Insects - Lepidoptera (butterflies and moths) - Cotton bollworm (Helicoverpa spp.)
Neomycin Phosphotransferase II - Escherichia coli - ECOLX
Resistance to antibiotics - Kanamycin
Beta-glucuronidase coding sequence - Escherichia coli - ECOLX
Selectable marker genes and reporter genes
Notes regarding the genetic elements introduced or modified in this LMO
This modified cotton contains the insecticidal cry1Ab/Ac gene which imparts resistance against Lepidoptera. The LMO also contains the selectable markers nptII to isolate transformed seedlings and a GUS gene cassette as a reporter gene.

Bt-cotton was generated by Pollen-Tube-Pathway mediated plasmid-DNA delivary into the embryo-sacs/egg apparatus. Following integration with the fertilized egg, the transformed embryos were detected by the nptII kanamycin selection system of the germinating seedlings. Putative transformants were analysed through Southerns and assayed for the level of insect resistance

The Bt transgene in the converted Indian inbred lines behaves as a single dominant Mendelian factor and is stably integrated in the plant genome.

The cry1Ab/Ac gene derived from Bacillus thuringiensis subsp. kurstaki (B.t.k.).
