Abstract

The knowledge that the plant-parasitic nematode hyperparasite Pasteuria penetrans is important in nematode suppressive soils has long been recognised. The ability to mass produce this organism in vitro circumvents one of its major constraints. However, successful biological control can only be established if the strains that are deployed can attach to and infect pest nematodes. Currently, in respect to the Pasteuria that infects root-knot nematodes (Meloidogyne spp), it is thought that collagen-like fibres on the surface of the endospore are interacting with a receptor on the nematode cuticle and that mucin-like molecules play an important role in modulating this process. Here we report that an antibody raised to whole endospores of P. penetrans also recognises extracts from endospores of Bacillus thuringiensis (Bt), suggesting that Bt can be used as a model for Pasteuria endospores. Bioinformatics shows that mucin-like genes identified in C. elegans are present in Globodera pallida.
