Fig. 2: Small secreted proteins from soil-dwelling fungi may selectively influence the microbiome found within the hyphosphere.

Theoretical framework representing how fungal secreted proteins and exudates may act on the microbiome to recruit specific microbes and alter microbiome functional composition (represented by the pie charts) or how SSPs secreted from fungal hyphae may stimulate the microbiome to assist in substrate breakdown and nutrient acquisition.
