The sugarcane was modified for resistance to sugarcane borer (Diatraea saccharalis) through the expression of Bacillus thuringiensis Cry1Ac. The sugarcane additionally contains Streptomyces hygroscopicus phosphinothricin N-acetyltransferase gene as a selectable marker.

Notes regarding the genetic elements introduced or modified in this LMO
Genetic cassettes:
The modified sugarcane contains two gene cassettes: Bacillus thuringiensis cry1Ac and Streptomyces hygroscopicus phosphothricin N-acetyltransferase (pat). Both gene cassettes are under transcriptional control of the Zea mays ubiquitin promoter and the Agrobacterium tumefaciens nopaline synthase terminator.

- The coding sequence for cry1Ac was optimized for expression in sugarcane (sugarcane preferred codons).
- High levels of transcription are expected due to the constitutive nature of the ubiquitin promoter.
LMO characteristics

  • Selectable marker genes and reporter genes
Common use(s)
  • Food
  • Biofuel
Detection method(s)
Additional information
The Cry1Ac encodes a 615 amino acid protein with an estimated molecular weight of 68 kDa. The insecticidal core of the protein is 52 kDA.

DNA and protein on sugar samples produced from this modified sugarcane were unable to detection Cry1Ac or PAT (below the levels of detection) according Gianotto et al. (2019) (see attached document).
