    In order to exploit fully the biocontrol potential of the nematophagous fungus Verticillium chlamydosporium, it is important to understand the ecology of the fungus in soil, and interactions with both plant and nematode hosts. Several approaches for studying the fungus in soil and the root environment are compared. These include a semi-selective medium for V. chlamydosporium, PCR primers specific for the fungal beta -tubulin gene, and monoclonal antibodies. In addition to providing a target for species-specific primers, the beta -tubulin gene is implicated in resistance to the fungicides used in the semi-selective medium, and the genetic basis for this is investigated. Culture and PCR-based methods were used to screen for the presence of the fungus in field soils known to have been suppressive to cereal cyst nematode and that contained V. chlamydosporium populations. Monoclonal antibodies specific for either hyphae or conidia of the fungus were obtained, and their application as a tool for visualising the infection process on the root was explored.
