This review focuses on the proteins and secretions of sedentary plant parasitic nematodes potentially important for plant–nematode interactions. These nematodes are well equipped for parasitism of plants. Having acquired the ability to manipulate fundamental aspects of plant biology, they are able to hijack host-cell development to make their feeding site. They feed exclusively from feeding sites as they complete their life cycle, satisfying their nutritional demands for development and reproduction. Biochemical and genomic approaches have been used successfully to identify a number of nematode parasitism genes. So far, 65 204 expressed sequence tags (ESTs) have been generated for six Meloidogyne species and sequencing projects, currently in progress, will underpin genomic comparisons of Meloidogyne spp. with sequences of other pathogens and generate genechip microarrays to undertake profiling studies of up- and down-regulated genes during the infection process. RNA interference provides a molecular genetic tool to study gene function in parasitism. These methods should provide new data to help our understanding of how parasitic nematodes infect their hosts, leading to the identification of novel pathogenicity genes.

Keywords: Globodera sp., Meloidogyne sp., nematode secretions, monoclonal antibodies, nematode genes
