Banana modified for Xanthomonas wilt disease resistance
EN
PFLP
No
The banana was modified for resistance to Xanthomonas wilt disease caused by Xanthomonas campestris pv. musacearum. The modified banana expresses Capsicum annuum plant ferredoxin-like protein (pflp), which intensifies the host plant's hypersensitive response triggered by invading bacterial pathogens and leads to an increased production of reactive oxygen species. The modified banana plants did not demonstrate wilting when challenged with X. campestris. In addition to pflp, 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.

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

Transcription of Capsicum annuum plant ferredoxin-like protein (pflp) is under control of the Cauliflower Mosaic Virus (CaMV) 35S promoter and the nos terminator. Elevated levels transcription are expected due to the constitutive nature of the CaMV promoter.

Notes:
- The coding sequence of pflp is a cDNA copy of the natural transcript and thus introns are not present.
- PFLP contains an N-terminal peptide for localization to the chloroplasts of the cells. However, research has demonstrated that the transgenic protein may also be present in the cytoplasm.
- The transformation vector was derived from the pBI121 vector using a BamHI and SacI restriction digest.
