Abstract
An isolate of the nematode-trapping fungus Monacrosporium drechsleri was collected from cultures of the root-knot nematode Meloidogyne arenaria that had been maintained on tomato roots in greenhouse pots in Beltsville, Maryland, USA. To study host range of the isolate, the plant-parasitic nematodes Heterodera glycines, Meloidogyne incognita, and Pratylenchus zeae, and the free-living nematodes Caenorhabditis elegans and Panagrellus redivivus, were placed on fungal colonies of M. drechsleri grown in Petri dishes. Within one day, none of the nematodes placed near adhesive knobs were motile. To determine where M. drechsleri fits within the existing phylogeny of nematode-trapping fungi, the ITS-1 and 2 regions of rDNA and the nuclear gene EF1-a were sequenced in this study for the new isolate of M. drechsleri, for M. parvicolle, and for isolates of M. lysipagum and M. ellipsosporum distinct from those in Genbank. Parsimony trees were constructed showing the closest molecular relative of M. drechsleri to be the newly sequenced isolate of M. ellipsosporum; the latter had a highly divergent sequence from the morphological isolate of M. ellipsosporum recorded in GenBank. Because unique, ever-present and discrete morphological characters are absent in these related taxa, an independent molecular character should be considered essential for their accurate and rapid identification.
