Molecular diagnostics of plant-parasitic nematodes.

Biochemical and molecular methods of identification provide accurate, reliable diagnostic approaches for the identification of plant-parasitic nematodes. Initially, the techniques were used solely for taxonomic purposes, but increasingly became popular as a component of diagnostic information for farmers, growers and advisors. Diagnostic procedures are now available to differentiate the plant-pathogenic species from related but non-pathogenic species. The microscopic size of plant-parasitic nematodes poses problems and techniques have been developed to enrich samples to obtain qualitative and quantitative information on individual species. In addition, techniques are available to evaluate single nematodes, cysts or eggs of individual species in extracts from soil and plant tissue. Background information on early, pioneering work is presented as a prelude to discussion of diagnostic approaches. These include the use of isoelectric focusing (IEF) and restriction fragment length polymorphisms (RFLPs), progressing to antibody approaches and current polymerase chain reaction (PCR)-based techniques. DNA- or RNA-based techniques are the most widely used approaches for identification, taxonomy and phylogenetic studies, although the development and use of other methods has been, and in some cases still is, important. DNA bar coding and the extraction of DNA from preserved specimens will aid considerably in diagnostic information and these are discussed in the context of the future requirements of accurate and rapid diagnostic protocols.
