Plant-parasitic nematodes significantly threaten agriculture and forestry, causing various diseases. They cause annual losses of up to 178 billion dollars worldwide due their parasitism. Nematophagous fungi (NF) are valuable in controlling or reducing parasitic nematode diseases by killing through predatory behavior. This article summarizes the strategic approaches adopted NF capture, poison, consume for food. classified based on attacking strategies, including trapping, endoparasitism, toxin production, egg female Moreover, extracellular enzymes such as serine proteases chitinases also play an important role fungal infection disrupting cuticles, which act essential virulence factors target chemical constituents comprising cuticle eggshell.

Okaramine B from Penicillium demonstrates remarkable insecticidal efficacy; however, its biosynthetic yield is low, regulatory mechanism remains unknown. The present study found that difference was influenced by fermentation modes in okaramine-producing strains performed genomic comparative transcriptome analysis P. daleae strain NBP-49626, which exhibits significant features. NBP-49626 genome 37.4 Mb, it encodes 10,131 protein-encoding genes. Up 5097 differentially expressed genes (DEGs) were identified during submerged semi-solid processes. oka gene cluster, lacking transport genes, displayed distinct transcriptional patterns response B. Although transcription trends most known global are inconsistent with those oka, this five potential including two Zn(II)2Cys6 factors, Reg2 Reg19. A correlation also observed between tryptophan metabolism yields. In addition, several transporter as DEGs. These results confirmed using real-time quantitative PCR.
