Structure and ecological function of the soil microbiome affecting plant-soil feedbacks in the presence of a soil-borne pathogen.

ABSTRACT: Interactions between plants and soil microbes are important for plant growth and resistance. Through plant-soil-feedbacks, growth of a plant is influenced by the previous plant that was growing in the same soil. We performed a plant-soil feedback study with 37 grass, forb and legume species, to condition the soil and then tested the effects of plant-induced changes in soil microbiomes on the growth of the commercially important cut-flower Chrysanthemum in presence and absence of a pathogen. We analysed the fungal and bacterial communities in these soils using next-generation sequencing and examined their relationship with plant growth in inoculated soils with or without the root pathogen, Pythium ultimum. We show that a large part of the soil microbiome is plant species-specific while a sm
