Growth and Tuberization of Transgenic Potato Plants Expressing Sense and Antisense Sequences of Cu/Zn Superoxide Dismutase from Lily Chloroplasts

Growth and Tuberization of Transgenic Potato Plants Expressing Sense and Antisense Sequences of Cu/Zn Superoxide Dismutase from Lily Chloroplasts

Overexpression of a chloroplast-localized Cu/Zn superoxide dismutase (chCu/ZnSOD) obtained from lily significantly affects the growth and shape of potato tubers from an in vitro culture system (Kim et al., 2007). Here, we further characterized the sense and antisense transgenic potatoes grown and po...

Zusammenfassung:Overexpression of a chloroplast-localized Cu/Zn superoxide dismutase (chCu/ZnSOD) obtained from lily significantly affects the growth and shape of potato tubers from an in vitro culture system (Kim et al., 2007). Here, we further characterized the sense and antisense transgenic potatoes grown and pots and the greenhouse to investigate the potential for more practical field applications of such phenotypic manipulations. Under in vitro conditions, antisense transgenic plants showed increased shoot growth, delayed tuberization, and altered tuber shapes.
