从两个独立的原生质体融合实验中筛选出29个具有颠茄核基因组和烟草质粒组的杂交种。与前面描述的具有烟草核基因组和阿托罗亚细胞体的互惠、绿色和可育的胞质形成鲜明对比(Kushnir等人)。1987)，获得的植株都是完全缺乏叶绿素的。在对照融合实验中，分别将来自这些叶绿素缺乏的杂交种的阿托罗A核基因组和烟草核基因组与阿托罗或Scoplia质体体和烟草核基因组相结合。所有这些核基因组/质体组组合都产生了正常的绿色植物。因此，我们得出结论：烟草的质体组与颠茄核基因组是不亲和的。
SummaryTwenty-nine cybrids possessing an Atropa belladonna nuclear genome and a Nicotiana tabacum plastome were selected from two independent protoplast fusion experiments. In contrast to the previously described reciprocal, green and fertile cybrids with a Nicotiana nuclear genome and an Atropa plastome (Kushnir et al. 1987), the plants obtained were totally chlorophyll-deficient. An Atropa nuclear genome and a Nicotiana plastome from these chlorophyll-deficient cybrids were combined with an Atropa or a Scopolia plastome and a Nicotiana nuclear genome, respectively, in control fusion experiments. All of these nuclear genome/plastome combinations gave rise to normal, green plants. Therefore, we conclude that an N. tabacum plastome is incompatible with an A. belladonna nuclear genome.
