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.
