Microbial core taxa that are unique and shared by the soil, phyllosphere, and aphid compartments. Network visualization for samples originating from oak seedlings infested with aphids grown in clayey (a), mixed (b), and sandy c soil microbiomes. Core taxa (≥ 50% prevalence in the respective compartment-soil type combination) at genus level, with bacterial and fungal datasets combined. Edge widths corresponds to relative abundance in the respective compartment (soil, phyllosphere, or aphids). Soil taxa labels of the clayey (n = 153), mixed (n = 186), and sandy soil (n = 270) compartments were not adjusted in size to increase clarity, except for the dominant genus Lyophyllum
