Abstract

During routine screening of soil samples for potato cyst nematodes, a morphologically variant cyst was detected. The internal transcribed spacer regions of the ribosomal DNA repeat unit from individual juveniles hatched from the cyst were amplified by PCR. The resulting products were digested with a range of restriction enzymes and their RFLP profiles compared with standard samples ofGlobodera rostochiensisandGlobodera pallida. Most of the RFLP profiles yielded patterns similar to those ofG. pallidaalthough some restriction enzymes gave hybrid patterns showing elements of bothG. rostochiensisandG. pallida. Clones of individual ITS regions from a single nematode from the variant cyst displayed either aG. pallidaorG. rostochiensispattern. [ABSTRACT FROM AUTHOR] more...

Abstract

Phylogenetic systematics is based on genealogy, rather than overall similarity, and a cladogram constitutes a potentially falsifiable hypothesis that can bring a new perspective to our understanding of the distribution and biogeography of a group of organisms. Sufficient data now exist for phylogenetic analysis of the Heteroderidae. New data at new levels of analysis comprise potential falsifiers for existing schemes. more...
