Plant roots interact with many bacteria, fungi, and microscopic organisms within the soil that can impact how well plants grow. Some of these are animals called nematodes, they an especially important part life in soil. Nematodes be good, bad, neutral for plants. scientists nematologists study nematodes to prevent bad ones from damaging crops, like carrots. Nematologists other partner up help f...

A quantitative PCR procedure targeting the Heterodera glycines ortholog of the Caenorhabditis elegans uncoordinated-78 gene was developed. The procedure estimated the quantity of H. glycines from metagenomic DNA samples isolated directly from field soil under agronomic production. The estimation of H. glycines quantity was determined in soil samples having other soil dwelling plant parasitic ne...

Many detrimental nematodes exist, including parasitic plant and animal nematodes. The Pleurotus ostreatus (oyster mushroom) is a famous mushroom that preys upon live nematodes. However, there have been no details reported on the mechanism of this predatory activity. Therefore, we investigated the predatory relationship between the nematode and P. ostreatus as a potential way of exterminating ot...

The impacts of two organic soil amendments on nematode abundance, community structure and soil characteristics were studied in field grown tomatoes. We hypothesized that as the raw (labile form) and composted (non-labile form) manures differ in their chemical composition and effect on microbial activity. Also they will have different effects on soil properties and directly and indirectly affect...

The potato rot nematode, Ditylenchus destructor, is a very destructive nematode pest on many agriculturally important crops worldwide, but the molecular characterization of its parasitism of plant has been limited. The effectors involved in nematode parasitism of plant for several sedentary endo-parasitic nematodes such as Heterodera glycines, Globodera rostochiensis and Meloidogyne incognita h...

abstract in order to identify the plant parasitic nematodes of potato fields, 55 soil samples and 60 infested tuber samples were collected from different fields in khorasan razavi province during 2005-2006 . soil samples were washed and nematodes were extracted by centrifugal flotation technique. according to de grisse, the extracted nematodes were fixed and transferred to glycerin. baermann fu...

The effect of tillage intensity on nematode community trophic structure and the role of nematodes in the regulation of decomposition rates in agroecosystems were examined. Conventional (CT) and no-tillage (NT) agroecosystems were sampled monthly for 1 year. Tillage affected nematode trophic structure and total abundance. Monthly mean densities of bacterivorous, fungivorous, and total nematodes ...

Plants can influence the level of herbivory experienced by neighboring plants. The importance such belowground associational effects are poorly understood. In this study we examine whether Jacobaea vulgaris provides resistance against nematodes to Thirteen species (6 forbs, 3 grasses and 4 legumes) were each grown in mixtures with J. monocultures. A nematode community was introduced half pots. ...
