Journal ArticleDOI
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
A ribosomal DNA-based framework for the detection and quantification of stress-sensitive nematode families in terrestrial habitats.
M.H.M. Holterman,Katarzyna Rybarczyk,Sven van den Elsen,Hanny van Megen,Paul Mooyman,Reyes Peña Santiago,Tom Bongers,Jaap Bakker,Johannes Helder +8 more
TL;DR: To illustrate the practicability of the proposed molecular framework, primers were designed for the detection of individual subclades within the order Mononchida in a complex DNA background and tested them in quantitative assays (real‐time polymerase chain reaction).
Journal ArticleDOI
Comparison of two short DNA barcoding loci (COI and COII) and two longer ribosomal DNA genes (SSU & LSU rRNA) for specimen identification among quarantine root-knot nematodes ( Meloidogyne spp.) and their close relatives
Sebastian Kiewnick,Martijn Holterman,Sven van den Elsen,Hanny van Megen,Juerg Ernst Frey,Johannes Helder +5 more
TL;DR: None of the four markers distinguished between the tropical species Meloidogyne incognita, M. javanica and M. arenaria, although the high level of mitochondrial heteroplasmy recently reported for M. chitwoodi was not found in the populations under investigation, suggesting this could be a regional phenomenon.
Journal ArticleDOI
SSU Ribosomal DNA-Based Monitoring of Nematode Assemblages Reveals Distinct Seasonal Fluctuations within Evolutionary Heterogeneous Feeding Guilds
M.T.W. Vervoort,J. Arie Vonk,Paul J. W. Mooijman,Sven van den Elsen,Hanny van Megen,P.T.M. Veenhuizen,Renske Landeweert,Jaap Bakker,Christian Mulder,Johannes Helder +9 more
TL;DR: A quantitative PCR-based tool for the detection of a consistent part of the soil nematofauna was developed based on a phylum-wide molecular framework consisting of 2,400 full-length SSU rDNA sequences, revealing ecological information about the soil food web that had been partly overlooked.
