In the current research, we focus on uniparental inheritance of chloroplast genome of the living fossil plant, L., one of the gymnosperms, using genomic data.•Our results provide strong genomic evidence to support plastid maternal inheritance mode of , which is different from most other gymnosperms.•The combination of manually genetic crosses and genomic data is proved to be an efficient way to investigate the inheritance mode of chloroplasts genome in land plants.•The current research also provides a case study for further research of plastid inheritance in gymnosperms using genomic techniques, which will contribute to a better understanding of cytologically uniparental inheritance mode and evolutionary mechanism of plastids in both gymnosperms and angiosperms.
在当前的研究中，我们利用基因组数据，聚焦于裸子植物之一的活化石植物银杏叶绿体基因组的单亲遗传。•我们的结果提供了强有力的基因组证据，支持银杏质体母系遗传模式，这与大多数其他裸子植物不同。•事实证明，人工遗传杂交与基因组数据相结合是研究陆地植物叶绿体基因组遗传模式的有效方法。•当前的研究还为利用基因组技术进一步研究裸子植物质体遗传提供了一个案例研究，这将有助于更好地理解裸子植物和被子植物中质体在细胞学上的单亲遗传模式及进化机制。
