  • Title: Plastid Transformation in Potato: An Important Source of Nutrition and Industrial Materials.
    Author: Valkov VT, Gargano D, Cardi T, Scotti N.
    Journal: Methods Mol Biol; 2021; 2317():247-256. PubMed ID: 34028773.
    Abstract:
    For a long time, plastid transformation has been a routine technology only in tobacco due to lack of effective selection and regeneration protocols, and, for some species, due to inefficient recombination using heterologous flanking regions in transformation vectors. Nevertheless, the availability of this technology to economically important crops offers new possibilities in plant breeding to manage pathogen resistance or improve nutritional value. Herein we describe an efficient plastid transformation protocol for potato (Solanum tuberosum subsp. tuberosum), achieved by the optimization of the tissue culture procedures and using transformation vectors carrying homologous potato flanking sequences. This protocol allowed to obtain up to one shoot per shot, an efficiency comparable to that usually accomplished in tobacco. Further, the method described in this chapter has been successfully used to regenerate potato transplastomic plants expressing recombinant GFP protein in chloroplasts and amyloplasts or long double-stranded RNAs for insect pest control.
