摘要: Lecanicillium attenuatum is an important nematophagous fungus with potential as a biopesticide against plant-parasitic nematodes. The Pr1A-like cuticle-degrading protease (Cdep1) gene originating from the entomopathogenic fungus Beauveria bassiana was transformed into the nematophagous fungus L. attenuatum using a polyethylene-glycol mediated protoplast-based transformation system. Protease activity was increased 0.64- to 1.63-fold 2-10 d after growth in the transformed L. attenuatum. Inhibition of egg-hatching and J2 motility of soybean cyst nematodes (Heterodera glycines) by cell-free fungal culture filtrates were enhanced by 17-76% 2-14 d and 43-152% 1-13 d after incubation, respectively.
