In sustainable, low-input cropping systems the natural roles of microorganisms in maintaining soil fertility and biocontrol of plant pathogens may be more important than in conventional agriculture where their significance has been marginalised by high inputs of agrochemicals. Better understanding of the interactions between arbuscular mycorrhizal fungi and other microorganisms is necessary for the development of sustainable management of soil fertility and crop production. Many studies of the influence of mycorrhizal colonisation on associated bacterial communities have been conducted, however, the mechanisms of interaction are still poorly understood. Novel approaches including PCR-based methods, stable isotope profiling, and molecular markers have begun to shed light on the activity, identity and spatiotemporal location of bacteria in the mycorrhizosphere. This paper reviews current knowledge concerning the interactions between arbuscular mycorrhizal fungi and other microorganisms, particularly bacteria, and discusses the implications these interactions may have in sustainable agriculture.
在可持续的低投入种植系统中,微生物在维持土壤肥力和对植物病原体进行生物防治方面的自然作用,可能比在传统农业中更为重要。在传统农业中,由于大量投入农用化学品,微生物的重要性已被边缘化。为了实现土壤肥力和作物生产的可持续管理,有必要更好地理解丛枝菌根真菌与其他微生物之间的相互作用。人们已经开展了许多关于菌根定殖对相关细菌群落影响的研究,然而,相互作用的机制仍知之甚少。包括基于PCR的方法、稳定同位素分析和分子标记在内的新方法,已开始揭示菌根际中细菌的活性、身份和时空位置。本文综述了有关丛枝菌根真菌与其他微生物,特别是细菌之间相互作用的现有知识,并讨论了这些相互作用对可持续农业可能产生的影响。
