Abstract: We have characterised three Meloidogyne artiellia genes, two of which may be specific to plant parasitic nematodes. The first gene shows similarity to chitin synthases from Caenorhabditis elegans and fungi. The M. artiellia chitin synthase is present as a single copy in the genome and is expressed in unhatched nematodes. It seems likely that nematode chitin synthases are involved in production of the eggshell chitin layer. We are examining the temporal and spatial expression patterns of the C. elegans and M. artiellia genes in more detail. The function of the other genes isolated is unclear. One gene is similar to bacterial genes involved in capsular polyglutamate biosynthesis. This gene has no homologs in the C. elegans genome or in the large animal parasite EST dataset. It is expressed in all M. artiellia stages examined. The third gene is small and is transcribed in all life cycle stages tested. No homologs of this gene are present in any of the databases, although proteins with similar Mr and predicted pI are present in C. elegans.
