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

Project description: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)

AoMbp1 interacts with AoSwi6 and plays pleiotropic roles in mycelial development, trap morphogenesis, and stress respone in the nematode-trapping fungus Arthrobotrys oligospora [RNA-Seq]

Project description:The fungal specific APSES family proteins involve in regulating fungal growth, development, and multiple biological processes. In this study, AoMbp1, an ortholog of Saccharomyces cerevisiae APSES-type transcription factor Mbp1, was functionally analyzed in a representative nematode-trapping fungus Arthrobotrys oligospora. Inactivation of Aombp1 caused a severe affect on the mycelial growth and development, the mycelial growth rate of ∆Aombp1 mutant was remarkably decreased, the hyphal septa were increased whereas the number of nuclei were significantly reduced, and the lipid droplet accumulation was remarkably increased. Meanwhile, the deletion of Aombp1 resulted a considerable reduction in the number of conidiophores and spore yield, which also caused abnormal spore morphology. In addition, the ∆Aombp1 mutants became more sensitive to several chemical stressors, especially to hyperosmotic reagents. Importantly, disruption of Aombp1 caused the number of traps and nematode-trapping ability were significantly reduced, and most of the traps have changed from their original three-dimensional structure to a planar shape. RNA-Seq, DAP-Seq and Y2H assay showed that AoMbp1 interacted with AoSwi6, and involved in regulating cell cycle, meiosis, lipid metabolism, DNA replication, mismatch repair and nucleotide excision repair. Our study elucidated the functions and potential regulatory mechanism of APSES protein Mbp1 in the mycelial development and trap morphogenesis of nematode-trapping fungi.
