in this research the effect of two species of arbuscular mycorrhizal fungi, glomus mosseae and glomus intraradices on root knot nematode, meloidogyne javanica was investigated and in different treatments the effects of this interaction on parameters of plant growth , nematode infection and mycorrhizal development were evaluated.shoot fresh and dry weight significantly increased in mycorrhizal t...

Observations in three Australian sugarcane fields suggested that the soil just under the trash blanket (the covering of crop residue that remains on the soil surface after crops are harvested) was suppressive to plant-parasitic nematodes. Roots were concentrated in this upper layer of soil but plant-parasitic nematode populations were relatively low and roots showed few signs of nematode damage...

Plant-parasitic nematodes were found in 4 of the 12 clades of phylum Nematoda. These nematodes in different clades may have originated independently from their free-living fungivorous ancestors. However, the exact evolutionary process of these parasites is unclear. Here, we sequenced the genome sequence of a migratory plant nematode, Ditylenchus destructor We performed comparative genomics amon...

BACKGROUND Third-stage larvae (L3) of the canine hookworm, Ancylostoma caninum, undergo arrested development preceding transmission to a host. Many of the mRNAs up-regulated at this stage are likely to encode proteins that facilitate the transition from a free-living to a parasitic larva. The initial phase of mammalian host invasion by A. caninum L3 (herein termed "activation") can be mimicked ...

Because of their free-living life cycle alternatives, Strongyloides and related nematode parasites may represent the best models for translating C. elegans science to the study of nematode parasitism. S. stercoralis, a significant pathogen of humans, can be maintained in laboratory dogs and gerbils. Biosafety precautions necessary for work with S. stercoralis, though unfamiliar to many C. elega...

A field experiment was conducted to investigate the soil application of two Rhizobacteria, (MTCC and Pf-5) and urea treatments, separately and in combination on free living and plant parasitic nematodes. All the treatments significantly decreased the number of plant-parasitic nematodes with the increasing of plant growth. Both Rhizobacteria and urea were separately effective in suppressing plan...
