Elevational patterns of soil nematode diversity, community structure and metabolic footprint in the Trikuta mountains of Northwestern Himalaya

Frontiers in Forests and Global Change, 2023
Nematodes are an integral part of soil biodiversity and play a vital role in soil nutrient cycling. The Himalayan mountainous ecosystems are amongst the extreme environments in the world.

Gastrointestinal nematode species burdens and host mortality in a feral sheep population [PDF]

, 2006
Every few years a large proportion of the feral sheep on Hirta, St Kilda die due to food shortage. The effects of malnutrition are exacerbated by gastrointestinal nematodes. As found in sheep flocks in mainland Britain, Teladorsagia circumcincta has long

The AAP gene family for amino acid permeases contributes to development of the cyst nematode Heterodera schachtii in roots of Arabidopsis [PDF]

, 2013
The beet cyst nematode Heterodera schachtii is able to infect Arabidopsis plants and induce feeding sites in the root. These syncytia are the only source of nutrients for the nematodes throughout their life and are a nutrient sink for the host plant.

Nematode chromosomes

Genetics, 2022
AbstractThe nematode Caenorhabditis elegans has shed light on many aspects of eukaryotic biology, including genetics, development, cell biology, and genomics. A major factor in the success of C. elegans as a model organism has been the availability, since the late 1990s, of an essentially gap-free and well-annotated nuclear genome sequence, divided ...

Natural variation of outcrossing in the hermaphroditic nematode Pristionchus pacificus [PDF]

, 2009
Background: Evolution of selfing can be associated with an increase in fixation of deleterious mutations, which in certain conditions can lead to species extinction.

The functional role and diversity of soil nematodes are stronger at high elevation in the lesser Himalayan Mountain ranges

Ecology and Evolution, 2021
Soil nematodes are a foremost component of terrestrial biodiversity; they display a whole gamut of trophic guilds and life strategies, and by their activity, affect major ecosystem process, such as organic matter degradation and carbon cycling.

Comparative efficacy of essential oil nanoemulsions and bioproducts as alternative strategies against root-knot nematode, and its impact on the growth and yield of Capsicum annuum L.

Journal of the Saudi Society of Agricultural Sciences, 2023
In a study to compare the effectiveness of some essential oil nanoemulsion and bioproducts as an alternative to chemical nematicide in control of root-knot nematode, Meloidogyne incognita parasitizing on chili pepper, Capsicum annuum L.

Signal sequence analysis of expressed sequence tags from the nematode Nippostrongylus brasiliensis and the evolution of secreted proteins in parasites [PDF]

, 2004
Parasitism is a highly successful mode of life and one that requires suites of gene adaptations to permit survival within a potentially hostile host.

Abundant variation in microsatellites of the parasitic nematode Trichostrongylus tenuis and linkage to a tandem repeat [PDF]

, 2006
An understanding of how genes move between and within populations of parasitic nematodes is important in combating the evolution and spread of anthelmintic resistance.
