苜蓿基因型驱动植物营养策略及其相关根际细菌群落。
通过植物遗传学来控制植物微生物群对那些寻求改善植物营养和健康的人越来越感兴趣。虽然已经开展了全基因组关联研究(GWAS)来确定驱动植物微生物组的植物基因,但需要更多的多学科研究来评估植物遗传学、植物微生物组和植物适应性之间的关系。采用元条形码技术,对155个核心品种的根际细菌群落特征和植物表型进行了分析,并通过GWAS技术对其遗传效应进行了研究。不同基因型的短尾松的生长和营养策略不同,但很少有基因座与这些生理生态性状相关。为了进一步研究,我们描述了其相关的根际细菌群落,以变形菌门、放线菌门和拟杆菌门为主,并定义了一个核心根际细菌群落。接下来,使用随机森林分析确定预测感兴趣的植物生态生理性状的候选细菌的发生率。其中一些是可遗传的,并确定了植物位点,确定了与激素刺激反应、全身获得性抗性、胁迫反应、营养饥饿或运输以及根系发育相关的基因。总之,这些结果表明,植物遗传学可以通过在一个连接良好的相互作用网络中利用关键细菌来影响植物的生长和营养策略。

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.
