Previously, a chloroplast-localized Cu,Zn superoxide dismutase (chCu,ZnSOD) was isolated from lily and the sense- and antisense- sequences of the lily chCu,ZnSOD were used to transform potato plants. Two selected lines, the sense- and anti-sense strand of transgenic plants, were further characterized for resistance to Erwinia carotovora, which is a severe pathogen affecting potato plants. Only the sense-strand transgenic potato, which contained less O₂- and more H₂O₂ than wild-type and antisense-strand transgenic plants, showed increased resistance to E. carotovora.
