The active effect of Rhizophagus irregularis inoculants on maize endophytic bacteria community

Abstract

Little has been reported on the effect of arbuscular mycorrhizal fungi (AMF) inoculants from in vitro dual culture system on the growth of maize and its endophytic microbial community. Our results suggest that AMF inoculants play an important role in influencing maize growth and diversity of endophytic bacterial communities. AMF inoculants significantly promote maize growth, especially AMF inoculants with modified Strullu‐Romand (MSR) medium. These inoculants also significantly increased the diversity of endophytic microbial communities, especially the abundance of beneficial bacterial flora, thus positively affecting maize growth. This study reveals the utility of AMF inoculants from in vitro dual culture system, which provides a basis for the development of environmentally friendly inoculants.
