Fig. 7 Ecological assembly mechanisms of phyllosphere fungal communities in Helianthemum songaricum. (a), (b) and (c) represent neutral community model analyses for all ecological niches, phyllosphere epiphytic fungi, and phyllosphere endophytic fungi, respectively. (d) Normalized stochastic rate (NST) analyses for phyllosphere epiphytic and endophytic fungi. (e) NST analyses for phyllosphere epiphytic fungi. (f) NST analyses for endophytic fungi.
