Raw Dataset for "Emerging dactylellinatone attractant aids in the predation of nematodes by nematode-trapping fungus Dactylellina haptotyla"

We identified dactylellinatone, a novel nematode chemoattractant from D. haptotyla that enhances fungal predatory efficiency. Heterologous expression and isotope-labeled feeding experiments confirmed that the Dlt gene cluster is directly responsible for the biosynthesis of dactylellinatone. We discovered that the expression of Dlt gene cluster was significantly upregulated during predation. Deletion of the core gene in the cluster not only disrupted dactylellinatone production but also reduced D. haptotyla's attraction to nematodes and its pathogenicity. Collectively, our work reveals that D. haptotyla can increase their predation efficiency when sensing the presence of nematodes by triggering the expression of Dlt gene cluster and initiating the synthesis of dactylellinatone.
