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.

The aim of this review was to undertake a survey of researchers working with plant-parasitic nematodes in order to determine a 'top 10' list of these pathogens based on scientific and economic…

Analysis of nematode infections on auxin-insensitive tomato and Arabidopsis mutants revealed various phenotypes ranging from complete inhibition of syncytium development to a decrease in hypertrophy and lateral root formation at the infection site.

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.
Endogenous cellulases in animals: isolation of beta-1, 4-endoglucanase genes from two species of plant-parasitic cyst nematodes.

The synthesis of EGases in the esophageal glands of the cyst nematodes Globodera rostochiensis and Heterodera glycines is reported on and it is revealed that the four catalytic domains belong to family 5 of the glycosyl hydrolases.
Small subunit rDNA-based phylogeny of the Tylenchida sheds light on relationships among some high-impact plant-parasitic nematodes and the evolution of plant feeding.

The data suggest that root knot nematodes have evolved from an ancestral member of the genus Pratylenchus, but it remains unclear which species is closest to this branching point, and resolution till species was observed, suggesting that SSU rDNA sequences have a potential for DNA barcode-based species identification with.

A metazoan pectinase gene is described that encodes a pectate lyase for breaking down the pECTin component of plant cell walls, the first example of non-symbiotic degradation of pectIn in plant cell Walls by an animal.
Use of allele specificity of comigrating AFLP markers to align genetic maps from different potato genotypes

The high incidence of corresponding AFLP alleles was confirmed by using an additional set of five primer combinations and the 733 AFLP markers identified provide a valuable reference collection for future mapping studies in potato, which may replace more laborious locus-specific marker techniques.

The current views of plant cell fate manipulation by these sedentary nematodes are integrated and an inventory of possible links between cell cycle activation and local, nematode-induced changes in auxin levels are made.
