背景与目的土传病原菌Phytophthora cinnamomicauses是一种致死性植物病害。亚磷酸盐是一种广泛应用于植物抗疫的有效药剂。亚磷酸盐作为一种常用的杀菌剂可能会影响土壤真菌群落的组成。然而，亚磷酸盐介导的保护地下的影响是直接或间接介导的土壤生物群是未知的。因此，探索地下的影响可能有助于亚磷酸盐使用的可持续性的评估和测试的假设直接与间接的影响，在病原体response.MethodsOur温室盆栽实验对Rhododendronspecies有后病原体或前病原体使用亚磷酸盐比较和评估植物和土壤真菌的反应，亚磷酸盐和卵菌病原体Phytophthora cinnamomi的存在。析因实验还包括有和没有病原体和土壤生物群处理，以测试交互作用。高通量测序分析了土壤真菌群落，我们测量了土壤真菌的多样性，均匀度和丰富度。它改变了土壤真菌群落的组成，和使用亚磷酸盐的时间确定的方式，其中真菌群落changed.Trichodermataxa也响应土壤亚磷酸盐和Phytophthora cinnamomi.ConclusionsThe拮抗真菌的好处，如Trichodermaare上下文相关的，这表明对病原体的保护取决于亚磷酸盐应用的时间。这项研究提供的证据表明，亚磷酸盐介导的病原体保护包括直接利益的植物和间接影响，通过土壤真菌群落介导。
Background and AimsThe soil-borne pathogenPhytophthora cinnamomicauses a deadly plant disease. Phosphite is widely used as an effective treatment to protect plants fromPhytophthora cinnamomi. Phosphite as a common fungicide might influence the composition of soil fungal communities. However, whether the belowground effects of phosphite-mediated protections are direct or indirectly mediated through soil biota are unknown. Therefore, exploring belowground effects could contribute to the evaluation of the sustainability of phosphite use and tests hypotheses about direct versus indirect effects in pathogen response.MethodsOur greenhouse pot experiment onRhododendronspecies had either an after-pathogen or a before-pathogen use of phosphite to compare and evaluate plant and soil fungal responses to phosphite and the presence of an oomycete pathogenPhytophthora cinnamomi. The factorial experiment also included with and without pathogen and soil biota treatments, for a test of interactive effects. High throughput sequencing analyzed the soil fungal communities, and we measured the diversity, evenness and richness of soil fungi.ResultsPhosphite effectively increased survival ofRhododendronspecies. It altered the composition of soil fungal communities, and the timing of using phosphite determined the way in which the fungal communities changed.Trichodermataxa also responded to soil phosphite andPhytophthora cinnamomi.ConclusionsThe benefits of antagonistic fungi such asTrichodermaare context-dependent, suggesting protection against pathogens depends on the timing of phosphite application. This study provides evidence that phosphite-mediated pathogen protection includes both direct benefits to plants and indirect effects mediated through the soil fungal community.
