The objective of this work was to isolate and identify fungi associated with R. reniformis in cotton roots. Soil samples were collected in cotton fields naturally infested with R. reniformis and from cotton stock plants cultured in the greenhouse. Nematodes extracted from the soil were observed under the stereoscope, and discolored eggs and vermiform stages colonized with mycelia were cultured ...

An N-acetylgalactosamine-specific protein was purified from mycelial homogenates of the nematode-trapping fungus Arthrobotrys oligospora by using affinity chromatography. The molecular weight of the protein was estimated at 22,000 by its comparative mobility on sodium dodecyl sulfate-polyacrylamide slab gels. Pretreatment of nematodes with the purified protein reduced entrapment, indicating a r...

The systematic classification of nematode-trapping fungi is redefined based on phylogenies inferred from sequence analyses of 28S rDNA, 5.8S rDNA and beta-tubulin genes. Molecular data were analyzed with maximum parsimony, maximum likelihood and Bayesian analysis. An emended generic concept of nematode-trapping fungi is provided. Arthrobotrys is characterized by adhesive networks, Dactylellina ...

Two nematode trapping fungi were isolated from aerated soil samples collected fron Anand district( Gujarat) India and identified on the basis of their culture –morphological characteristics and 18S rRNA gene sequencing as Arthrobotrys oligospora and Duddingtonia flagrans . These fungal isolates were assessed for their trapping efficiency further. Trapping structures such as ring like structures...

The systematic classification of nematodetrapping fungi is redefined based on phylogenies inferred from sequence analyses of 28S rDNA, 5.8S rDNA and b-tubulin genes. Molecular data were analyzed with maximum parsimony, maximum likelihood and Bayesian analysis. An emended generic concept of nematode-trapping fungi is provided. Arthrobotrys is characterized by adhesive networks, Dactylellina by a...

Insufficient nutrient and pest infection are two major predicaments for low crop yield in agriculture. Nematodes, a most infectious parasite pest in plants responsible for major yield loss. Chemical phosphate fertilizer made large reserves of it in soil, but part of it is made available to the plants because of irreversible fixation of it with divalent cation. In the present study, Arthrobotrys...

In vitro tests were carried out to assess the activity of 26 Brazilian isolates of predatory fungi of the genus Arthrobotrys on a free-living nematode (Panagrellus sp.) and on infective larvae of Haemonchus placei, a parasitic gastrointestinal nematode of cattle. The results showed that the free-living nematode Panagrellus sp. was the most preyed upon, compared to H. placei, for all the fungal ...
