Indole acetic acid-mediated fungal antagonism enriches beneficial Variovorax for enhanced phosphorus acquisition in Arachis hypogaea L.
Dynamic monitoring of pqqC-harbouring (pyrroloquinoline quinone) bacterial and fungal communities in rhizosphere soil was conducted across growth stages under conditions with or without Ph. liquidambaris colonization. Results revealed that Ph. liquidambaris inoculation significantly restructured both pqqC-harbouring bacterial and fungal communities, with optimized profiles strongly correlated with elevated rhizospheric available P content.
