Identification, phylogeny and phylogeography of circumfenestrate cyst nematodes (Nematoda:... AbstractSome 134 ITS rRNA gene sequences for circumfenestrate cyst nematodes and twosequences for non-cyst nematodes of the family Heteroderidae, of which 46were newly obtained, were analysed by phylogenetic and phylogeographicmethods. Sequence and phylogenetic analysis combined with knownmorphological, biological and geographical data allowed the identification,amongst samples original to this study, of several belonging to known validspecies as well as others that might be new species. The phylogeneticanalysis revealed six major clades for circumfenestrate cyst nematodes:i) Globodera from South and North America;ii) Globodera from Europe, Asia,Africa and Oceania; iii) Paradolichodera;iv) Punctodera; v)Cactodera; and vi)Betulodera. Monophylies of Punctodera,Cactodera and Betulodera were highlysupported. The Betulodera clade occupied a basal positionon all trees.

Abstract

AbstractSome 134 ITS rRNA gene sequences for circumfenestrate cyst nematodes and twosequences for non-cyst nematodes of the family Heteroderidae, of which 46were newly obtained, were analysed by phylogenetic and phylogeographicmethods. Sequence and phylogenetic analysis combined with knownmorphological, biological and geographical data allowed the identification,amongst samples original to this study, of several belonging to known validspecies as well as others that might be new species. The phylogeneticanalysis revealed six major clades for circumfenestrate cyst nematodes:i) Globodera from South and North America;ii) Globodera from Europe, Asia,Africa and Oceania; iii) Paradolichodera;iv) Punctodera; v)Cactodera; and vi)Betulodera. Monophylies of Punctodera,Cactodera and Betulodera were highlysupported. The Betulodera clade occupied a basal positionon all trees. Phylogeographic analysis suggested a North American origin ofPunctoderinae with possible further long distance dispersal to SouthAmerica, Africa and other regions. Molecular data supported synonymisationof G. achilleae with G. millefolii and ofG. hypolysi with G. artemisiae.PCR-RFLP diagnostic profiles for some Globodera andCactodera species are given. Problems of diagnosticsfor Globodera species using PCR with specific primers arediscussed.
