作物多样性的表型限制:功能性状空间的数据探索。
作物遗传多样性与功能多样性之间的关系是应对当代农业挑战的关键。然而,很少有方法可以量化遗传多样性与作物功能性状表达之间的关系。在此,我们引入了 "功能空间累积曲线",以分析性状空间如何随物种内作物基因型数量的增加而增加。我们探讨了功能空间累积曲线量化大麦(Hordeum vulgare)、水稻(Oryza sativa)、大豆(Glycine max)和硬质小麦(Triticum durum)这四种常见一年生作物的基因型-性状空间关系的潜力。我们还利用这些曲线来描述野生拟南芥的基因型-性状空间关系,这种植物没有经过人工选择。所有五个物种都表现出渐近的功能空间积累曲线,这表明种内作物功能多样性是有限的,其原因可能是:多个基因型所代表的显性表型;或基因型之间可能存在的功能冗余。我们的研究结果表明,随着基因型数量的增加,功能多样性的回报率会逐渐降低。我们的分析证明了功能空间累积曲线在量化作物性状空间占有率方面的功效,对管理农业生态系统中的作物多样性和作物育种计划中的遗传多样性具有重要意义。

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.
