摘要

具有大基因组的被子植物会受到核、细胞和生物体水平的限制，这可能会限制其表型可塑性和生态位，从而增加其灭绝的风险。因此，我们检验了基因组大的物种比基因组小的物种更有可能面临灭绝威胁的假设，以及基因组大小对三个选定协变量（生命形式、地方性和气候区）的影响各不相同的假设。我们整理了由 3250 个物种组成的被子植物代表性样本的基因组大小和灭绝风险信息，并利用系统发生学框架将这些信息与生命形式、特有性和气候区变量一起进行了分析。基因组大小与灭绝风险呈正相关，这种模式是由草本而非木本物种的信号驱动的，与气候和特有性无关。基因组大小对特有草本物种的影响更大，但在不同气候条件下的影响相对单一。除了通过特有性和气候的间接联系之外，基因组大小还与灭绝风险有直接和显著的联系。基因组大小可作为草本被子植物中与恢复力和脆弱性相关的难以测量参数的替代物。因此，基因组大小作为一种有用的生物属性值得进一步探索，以了解内在的灭绝风险并加强植物保护工作。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
