大多数被子植物的线粒体（mt）DNA显示母系遗传，虽然相对罕见的双亲或父系传递已被记录。瓜属（葫芦科）植物的线粒体DNA在种内和种间杂交中由父系传递。本研究以黄瓜（Cucumis sativus）的mt突变体为材料，筛选出罕见的mt DNA的母本或双亲传递，然后采用常规PCR和滴状数字（dd）PCR研究多态性mt标记在三代间的传递。我们观察到的证据，偶尔母亲和双亲传输的线粒体DNA在黄瓜。母体mtDNA特定区域的传递率可能高达17.8%，尽管这些母体区域的数量通常比父系传递区域低得多。不同组合的母亲和父亲的mt多态性检测后代跨世代，表明相对罕见的母亲区域可以成为主要的，并传递给后代，以增加几代人的mt DNA多样性。
The mitochondrial (mt) DNAs of most angiosperms show maternal inheritance, although relatively rare biparental or paternal transmission has been documented. The mt DNAs of plants in the genus Cucumis (family Cucurbitaceae) are paternally transmitted in intra- and inter-specific crosses. We used a mt mutant of cucumber (Cucumis sativus) to screen for rare maternal or biparental transmission of the mt DNA, and then used normal and droplet-digital (dd) PCR to study transmission of polymorphic mt markers across three generations. We observed evidence for occasional maternal and biparental transmission of the mt DNA in cucumber. The transmission of specific regions of the maternal mt DNA could be as high as 17.8%, although the amounts of these maternal regions were often much lower relative to paternally transmitted regions. Different combinations of maternal and paternal mt polymorphisms were detected in progenies across generations, indicating that relatively rare maternal regions can become predominant and be transmitted to progenies to increase mt DNA diversity over generations.
