Abstract

Globodera&amp;nbsp;species identification is based on specific morphological characteristics which are included in the majority of keys used for&amp;nbsp;Globodera&amp;nbsp;identification. To confirm and make more precise the morphometrical method, other methods have been developed. At Agricultural Institute of Slovenia, molecular and biochemical methods are applied. With the use of PCR-RFLP method we try to distinguish between&amp;nbsp;G. rostochiensis,&amp;nbsp;G. pallida&amp;nbsp;and&amp;nbsp;G. tabacum. Patterns of nematode DNA digested with restriction endonucleases and subjected to agarose gel electrophoresis are analysed. Differences in DNA sequence result in the number and size of fragments produced (RFLPs). For the differentiation of all three nematodes we have introduced a method for protein electrophoresis. Samples are compared after being separated by polyacrilamide slab gel electrophoresis. Proteins are visualised after silver staining. &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;
