摘要

豆科植物与根瘤菌建立了固氮共生关系。为了研究这种权衡，我们使用了一个三方系统，包括模式豆科植物日本莲、其根瘤菌共生体中根瘤菌（Mesorhizobium loti）和土传病原体赤霉病菌（Ralstonia solanacearum）。我们研究了互生对植物防御的影响，以及植物防御对互生的相互影响。我们发现，莲花与根瘤菌的相互作用提高了莲花与年龄相关的对 Ralstonia 的抗性，尤其是在引发结瘤的情况下。相反，年龄相关抗性并不影响病原体侵袭下的结核器官发生或功能。这种抗性质疑了高效防御反应与互惠相互作用之间的干扰概念，对农业用途具有重大意义，因为它不仅限制了病原体的定植，还能保持固氮作用和产量。

Lotus resistance against Ralstonia is enhanced by Mesorhizobium and does not impair mutualism

Legumes establish nitrogen-fixing symbioses with rhizobia. On the contrary, they can be attacked concomitantly by pathogens, raising the question of potential trade-offs between mutualism and immunity.
In order to study such trade-offs, we used a tripartite system involving the model legume Lotus japonicus, its rhizobial symbiont Mesorhizobium loti and the soilborne pathogen Ralstonia solanacearum. We investigated the impact of mutualism on plant defense and the reciprocal influence of plant defense on mutualism.
We found that Lotus age-related resistance against Ralstonia was improved by the interaction with rhizobia especially when nodulation is triggered. Conversely, age-related resistance did not compromise nodule organogenesis or functioning under pathogen attack. Proteomic characterization indicates that this resistance is associated with distinct proteome modifications in roots and nodules.
This resistance questions the concept of interference between efficient defense reactions and mutualistic interactions and is of great interest for agricultural purposes as it not only restricts pathogen colonization, but would also preserve nitrogen fixation and yield.

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.
