Abstract

•Chen et al. found ancient WGDs cluster around major environmental disruptions from Cretaceous to Neogene.•Polyploids are disadvantaged in stable conditions but gain advantages during severe crises.•WGD establishment follows two regimes: background diversity-dependent rates and episodic pulses from crises.•Chen et al. suggest Anthropocene climate change and habitat disruption may foster new polyploids with long-term potential.

这是解决多倍体悖论的里程碑。

•Chen等人发现，从白垩纪到新近纪，古代WGDs聚集在主要环境破坏周围。•多倍体在稳定条件下处于不利地位，但在严重危机期间获得优势。•世界发展目标的建立遵循两种制度：背景多样性依赖率和危机的偶发脉冲。•Chen等人认为，人类世的气候变化和栖息地破坏可能培育出具有长期潜力的新的多倍体。

期刊介绍： Plant Diversity (formerly Plant Diversity and Resources) is an international plant science journal that publishes substantial original research and review papers that advance our understanding of the past and current distribution of plants, contribute to the development of more phylogenetically accurate taxonomic classifications, present new findings on or insights into evolutionary processes and mechanisms that are of interest to the community of plant systematic and evolutionary biologists. While the focus of the journal is on biodiversity, ecology and evolution of East Asian flora, it is not limited to these topics. Applied evolutionary issues, such as climate change and conservation biology, are welcome, especially if they address conceptual problems. Theoretical papers are equally welcome. Preference is given to concise, clearly written papers focusing on precisely framed questions or hypotheses. Papers that are purely descriptive have a low chance of acceptance. Fields covered by the journal include: plant systematics and taxonomy- evolutionary developmental biology- reproductive biology- phylo- and biogeography- evolutionary ecology- population biology- conservation biology- palaeobotany- molecular evolution- comparative and evolutionary genomics- physiology- biochemistry
