Arthrobotrys iridis 316A_c6_1 was sequenced for JGI Community Sequencing Project “Defensive Mutualism of Fungal Root Endophytes of Soybean”. We are investigating the potential role of fungal endophytes isolated from soybean roots in protecting against two root pathogens: 1) the root rot fungus causing Soybean Sudden Death Syndrome (Fusarium virguliforme) and the soybean cyst nematode (Heterodera glycines). These fungi were screened for either anti-fungal or anti-nematode activity in-vitro and genome, transcriptome, and metabolome sequencing will address possible mechanisms of antagonism against these pathogens.

This isolate of Arthrobotyris iridis, a nematode trapping fungus in the order Orbiliales (Ascomycota) was isolated from soybean roots and showed antagonism against the SDS pathogen F. virguliforme.
