Summary
In the present study, the influence of Bacillus subtilis JA on arbuscular mycorrhizal fungi (AMF) was evaluated by either pot culture or in vitro conditions, respectively. Under the pot culture conditions, the inoculation of B. subtilis JA decreased the frequency (% F) of the root colonization by indigenous arbuscular mycorrhizal fungi and the shoot dry weight of maize (Zea mays L.), but had no apparent effect on the intensity (% I) of AM fungal root colonization. The unknown volatile emitted from the B. subtilis JA in vitro significantly inhibited spore germination and the hyphal growth in the dual-compartment experiments. Moreover, the data from the direct interaction between B. subtilis JA and Glomus etunicatum showed that soluble antifungal lipopeptides influenced the development of AMF. Therefore, the application of antifungal Bacillus strains should take the compatibility with the indigenous beneficial fungi into consideration.
