An unusual biparental mode of plastid inheritance was found in pea, in a cross associated with nuclear-cytoplasmic incompatibility manifested as deficiency of chlorophyll pigmentation. Plastid DNA marker trnK and mitochondrial DNA marker cox1 were analyzed in F1 progeny that received cytoplasm from an accession of a wild subspecies Pisum sativum ssp. elatius. Plants with sectors of green tissue on leaves and seed cotyledons with green patches on an otherwise chlorotic background were found to carry paternally inherited plastid DNA, suggesting that photosynthetic function was affected by nuclear-cytoplasmic conflict and required proliferation of paternally inherited plastids for normal performance. The paternally inherited plastid DNA marker was also observed in the roots. The presence of the paternal marker in cotyledons, roots and leaves was independent of each other. Inheritance of the mitochondrial DNA marker cox1 appeared to be of the maternal type.
在豌豆中发现了一种不寻常的质体双亲遗传模式，该模式出现在一个与核质不相容相关的杂交组合中，表现为叶绿素色素沉着不足。对从野生亚种豌豆（Pisum sativum ssp. elatius）的一个种质中获得细胞质的F1后代进行了质体DNA标记trnK和线粒体DNA标记cox1分析。在叶片上有绿色组织区域以及种子子叶在黄化背景上有绿色斑块的植株被发现携带父本遗传的质体DNA，这表明光合功能受到核质冲突的影响，并且正常功能需要父本遗传的质体增殖。在根中也观察到了父本遗传的质体DNA标记。子叶、根和叶中父本标记的存在相互独立。线粒体DNA标记cox1的遗传似乎是母系类型。
