摘要

对大型植物物种表型空间的探索大大增加了我们对植物王国多样化过程的理解。然而，这种进步主要依赖于种间比较，这种比较有几个局限性。在这里，我们在田地里培育了一套独特的179个硬粒小麦自交系，即膨胀小麦。硬粒小麦具有不同程度的人工选择特征。我们测量了地上和地下性状以及农艺性状，以探索功能和农艺性状空间，并研究性状与农艺性能的关系。我们发现，小麦功能性状空间与先前描述的全球跨物种空间具有共性，具有两个主要的变异轴：根系觅食轴和慢速-快速权衡轴。此外，与功能性状不同，我们在农艺性状的变异上检测到了明显的人工选择特征。有趣的是，我们发现了可以优化作物性能的替代表型组合。我们的工作带来了关于驯化植物表型空间结构的深刻知识，以及对人工选择的表型权衡的维持，对植物育种中的无权衡和多标准选择具有启示意义。

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.
