The cauliflower (Brassica oleracea) was modified for resistance to Lepidoptera pests through the introduction and expression of Bacillus thuringiensis crystal protein, Cry1Ac. The protein forms pores in the midgut lining of susceptible pests, leading to cell lysis and septicemia. Additionally, the cauliflower contains an Escherichia coli neomycin phosphotransferase II cassette for kanamycin selection during transformation.

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.

  • BCH-GENE-SCBD-100366-6 CaMV Enhanced 35S promoter | Cauliflower mosaic virus (CaMV)
    Promoter
The modified cauliflower contains two gene cassettes: Escherichia coli neomycin phosphotransferase II (nptII) and Bacillus thuringiensis cry1Ac.

Transcription of nptII commences from a Cauliflower mosaic virus (CaMV) 35S promoter and terminates at a CaMV 35S terminator. Due to the viral promoters, transcription of nptII is expected to occur at elevated levels in all plant tissues.

Transcription of cry1Ac is controlled by a CaMV enhanced 35S promoter. Transcription is expected to occur at very high levels in all tissues due to the enhanced nature (duplicated enhancer) of the viral promoter.
