rapid identification of cyst (heterodera spp., globodera spp.) and root-knot (meloidogyne spp.) nematodes on the basis of its2 sequence variation detected by pcr-single-strand conformational polymorphism (pcr-sscp) in cultures and field samples.	cyst and root-knot nematodes show high levels of gross morphological similarity. this presents difficulties for the study of their ecology in natural ecosystems. in this study, cyst and root-knot nematode species, as well as some ectoparasitic nematode species, were identified using the second internal transcribed spacer (its2) sequence variation detected by polymerase chain reaction-single-strand conformational polymorphism (pcr-sscp). the its2 region was sufficiently variable within the taxa i ...	2000	10972762
morphological and molecular characteristics of a new species of pasteuria parasitic on meloidogyne ardenensis.	a species of the hyper-parasitic bacterium pasteuria was isolated from the root-knot nematode meloidogyne ardenensis infecting the roots of ash (fraxinus excelsior). it is morphologically different from some other pasteuria pathogens of nematodes in that the spores lack a basal ring on the ventral side of the spore and have a unique clumping nature. transmission electron microscopy (tem) showed that the clumps of spores are not random aggregates but result from the disintegration of the suicide ...	2007	17399736
