Microsatellite loci in the phytoparasitic nematode Globodera.
A Globodera pallida genomic library, population Guiclan (Pa2/3), was screened for TG and TC microsatellite motifs. Screening of 50,000 clones revealed 48 positive matches. After sequencing, primers were designed to amplify 14 microsatellite loci. The specificity of the loci was tested with DNA templates of other populations of G. pallida, and also on other species of Globodera. Appearance of amplification products on several of these DNA templates showed that the microsatellite flanking regions are relatively conserved between G. pallida populations as well as between Globodera species. Evidence for allele polymorphism between individuals was demonstrated by using nine loci primers, in G. pallida population Guiclan and from a population of a closely related species G. "mexicana". Some alleles appeared to be species specific.
