Banana resistant to Xanthomonas wilt disease
EN
HRAP-PFLP
No
The modified banana was a result of a stacked event and expresses Capsicum annuum plant ferredoxin-like protein and hypersensitive response-assisting protein for resistance to the bacterium Xanthomonas campestris pv. musacearum, the causal agent of Xanthomonas wilt disease. Both proteins intensify the hypersensitive response and increase reactive oxygen species in response to the pathogen associated molecular pattern, harpinPSS, and thus confer resistance to Gram negative bacterial pathogens, such as X. campestris. When challenged with X. campestris during glasshouse experiments, the modified banana plants did not exhibit wilting or signs of successful infection. In addition, the modified banana also contains a selectable marker, Escherichia coli neomycin phosphotransferase II, for kanamycin selection during transformation.
EN
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.

Gene expression
Transcription of Escherichia coli neomycin phosphotransferase II is under control of the Agrobacterium tumefaciens nopaline synthase (nos) promoter and terminator. (clockwise direction)

Transcription of Capsicum annuum plant ferredoxin-like protein (pflp) is under control of the Cauliflower Mosaic Virus (CaMV) 35S promoter and the nos terminator. (counterclockwise direction)

Transcription of C. annuum hypersensitive response assisting protein (hrap) is under control of the CaMV 35S promoter and the nos terminator. (clockwise direction)

Note:
- The coding sequence of pflp and hrap are cDNA copies of the natural transcript and thus introns are not present.
- Elevated levels of the Pflp and Hrap are expected due to the constitutive nature of the CaMV promoter.
- PFLP contains an N-terminal peptide for localization to the chloroplasts of the cells.
- The transformation vector was derived from the pBI-HRAP vector, which was obtained by using a BamHI and SacI restriction digest to remove the GUS reporter. A further HindIII digest allowed for the insertion of the pflp cassette in the opposite orientation.
