The sugarcane (Saccharum officinarum) event CTC-92015-7 expresses the Cry1Ac protein, which confers resistance to the sugarcane borer (Diatraea saccharalis), and the NPTII protein, used as a kanamycin selectable marker during transformation. This event uses sugarcane variety RB 92579 as the genetic background and thus differs from the other events developed by the Centro de Tecnologia Canavieira.

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.

  • Agrobacterium-mediated DNA transfer
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
The modified sugarcane contains two gene cassettes: Bacillus thuringiensis crystal protein (cry1Ac) and Escherichia coli neomycin phosphotransferase II (nptII).

The cry1Ac coding sequence is under control of an enhanced Cauliflower mosaic virus 35S promoter and 35S terminator. The gene cassette additionally contains a Triticum aestivum 5' untranslated leader from chlorophyll a/b-binding protein and an Oryza sativa actin 1 intron for enhanced expression of cry1Ac. Due to the enhanced promoter and genetic elements, high levels of constitutive expression of Cry1Ac are expected.

The nptII coding sequence is under control of a Zea mays ubiquitin promoter and Agrobacterium tumefaciens nopaline synthase terminator. Expression of NPTII is expected in all plant tissues due to the nature of the ubiquitin promoter.

Note: The modified sugarcane event CTC-92015-7 expresses the same Cry1Ac and NPTII proteins, with 100% sequence homology, expressed by the reference CTC93209-4 modified sugarcane (see https://bch.cbd.int/en/database/record?documentID=115563).
