Phylum-Wide Analysis of SSU rDNA Reveals Deep Phylogenetic Relationships among Nematodes and Accelerated Evolution toward Crown Clades
Martijn Holterman,Andre van der Wurff,Sven van den Elsen,Hanny van Megen,Tom Bongers,Oleksandr Holovachov,Jaap Bakker,Johannes Helder +7 more
TL;DR: The exclusive common presence of fungivorous and plant parasitic nematodes supports a long-standing hypothesis that states that plant parasitic Nematodes arose from fungivory ancestors.
Journal ArticleDOI
A phylogenetic tree of nematodes based on about 1200 full-length small subunit ribosomal DNA sequences.
Hanny van Megen,Sven van den Elsen,Martijn Holterman,Gerrit Karssen,Paul Mooyman,Tom Bongers,Oleksandr Holovachov,Jaap Bakker,Johannes Helder +8 more
TL;DR: The extensiveness of convergent evolution is one of the most striking phenomena observed in the phylogenetic tree presented here – it is hard to find a morphological, ecological or biological characteristic that has not arisen at least twice during nematode evolution.
Journal ArticleDOI
Phylogeny of Cephalobina (Nematoda): molecular evidence for recurrent evolution of probolae and incongruence with traditional classifications.
Steven A. Nadler,Paul De Ley,Manuel Mundo-Ocampo,Ashleigh B. Smythe,S. Patricia Stock,Daniel J. Bumbarger,Byron J. Adams,Irma Tandingan De Ley,Oleksandr Holovachov,James G. Baldwin +9 more
TL;DR: For Cephalobidae, molecular trees do not support traditional genera as natural groups, but it remains untested if deconstructing probolae morphotypes or other structural features into finer component characters may reveal homologies that help delimit evolutionary lineages.
