Abstract

Plant-associated microbial diversity encompasses symbionts, protecting their host against various aggressions. Mycorrhizal and rhizospheric microorganisms buffer effects of soil toxic compounds and soil-borne pathogens. Endophytic bacteria and fungi, some of which are vertically inherited through seeds, take part in plant protection by acting directly on aggressive factors (mainly pathogens and herbivores) or by enhancing plant responses. Plant protective microbial symbionts determine the ecological success of plants; they drastically modify plant communities and related trophic webs. This review suggests approaches to improve the inventory of diversity and functions of in situ plant-associated microorganisms.

摘要

与植物相关的微生物多样性包括共生体，可保护其宿主免受各种侵害。菌根和根际微生物可缓冲土壤有毒化合物和土传病原体的影响。内生细菌和真菌，其中一些通过种子垂直遗传，通过直接作用于侵害因子（主要是病原体和食草动物）或增强植物反应来参与植物保护。植物保护性微生物共生体决定了植物的生态成功；它们极大地改变了植物群落和相关的营养网络。本综述提出了改进原位植物相关微生物多样性和功能清单的方法。
