Genome-wide expression profiling of nematode-trapping fungus Arthrobotrys oligospora ku70 and ste12 strains upon nematode exposure

We report the transcriptomic comparisions between ku70 control and ste12 mutant strains in nematode-trapping fungus Arthrobotrys oligospora when induced with nematodes. Fungal Ste12 transcription factor and the upstream MAPK cascade are highly conserved and plays a role in host sensing and pathogenesis in various fungal pathogens. Identification of Ste12-dependent in A. oligospora may provide further insights into the molecular mechanisms of nematode-sensing and trap morphogenesis. The reference assemly used for remapping is A. oligospora TWF154 (GenBank assembly accession: GCA_004768765.1) Examination of the transcriptional regulation controlled by Ste12 transcription factor upon nematode contact in Arthrobotrys oligospora
