| 摘要: |
| 石松类和蕨类植物作为古老的维管植物类群，其基因组具有独特特征和重要研究价值，在植物演化中占据关键地位。本文综述了石松类和蕨类植物基因组的核心特征，包括基因组大小与染色体数目显著相关、重复序列比例高、全基因组复制与多倍化频繁等；同时，梳理探讨了基因组进化机制，阐述了基因组解析在水平基因转移等方面的关键发现。此外，本文还展望了未来研究方向和策略，以期推动石松类和蕨类植物基因组研究，为理解陆地植物演化、促进相关学科发展及蕨类资源利用提供参考。 |

| Abstract: |
| As ancient vascular plant groups,lycophytes and ferns occupy a crucial position in plant evolution,and their genomes possess unique characteristics and significant research value.This article reviews the core features of lycophyte and fern genomes,including the significant correlations between genome sizes and chromosome counts,a high proportion of repetitive sequences,and frequent whole-genome duplication and polyploidization events.Meanwhile,this article sorts out and discusses the mechanisms of genome evolution and expounds on the key findings of genome analysis in aspects such as horizontal gene transfer.In addition,this article makes an outlook on the future research directions and strategies to advance the study of lycophyte and fern genomes,providing references for understanding the evolution of terrestrial plants,promoting the development of related disciplines,and facilitating the utilization of fern resources. |
