The hybrid plants with transformed plastids were regenerated after PEG fusion of chlorophyll-deficient Lycopersicon peruvianum leaf mesophyll protoplasts and leaf mesophyll protoplasts of Solanum rickii, which were previously genetically transformed and as the result were resistant to streptomycine and spectinomycine. The hybrid callus selection was based on the inability of the Lycopersicon peruvianum minicalli to have the green coloration and on the inability of gamma-preirradiated Solanum rickii protoplasts to divide. The hybrids were identified on the base of PCR analyses of nuclear and plastid DNA.
将先前经过基因转化并因此对链霉素和壮观霉素具有抗性的秘鲁番茄叶片叶肉原生质体与里氏茄叶片叶肉原生质体进行聚乙二醇融合后,再生出了具有转化质体的杂交植株。杂交愈伤组织的筛选基于秘鲁番茄微小愈伤组织无法呈现绿色以及经γ射线预辐照的里氏茄原生质体无法分裂这两点。通过对核DNA和质体DNA进行PCR分析来鉴定杂交种。
