Microbial communities that are associated with plant roots are highly diverse and harbor tens of thousands of species. This so-called microbiome controls plant health through several mechanisms including the suppression of infectious diseases, which is especially prominent in disease suppressive soils. The mechanisms implicated in disease suppression include competition for nutrients, antibiosis, and induced systemic resistance (ISR). For many biological control agents ISR has been recognized as the mechanism that at least partly explains disease suppression. Implications of ISR on recruitment and functioning of the rhizosphere microbiome are discussed.
与植物根系相关的微生物群落具有高度的多样性,蕴藏着成千上万的物种。这个所谓的微生物组通过多种机制控制着植物的健康,包括抑制传染病,这在抑制疾病的土壤中尤为明显。参与疾病抑制的机制包括营养竞争、抗生性和诱导系统抗性(ISR)。对于许多生物防治剂,ISR 已被认为是至少部分解释疾病抑制的机制。讨论了 ISR 对根际微生物组的招募和功能的影响。
