  • 28 November 2003
This review examines the discovery of naturally occurring phytochemicals antagonistic toward plant-parasitic and other nematodes. Higher plants have yielded a broad spectrum of active compounds,Expand
Sterol effects and sites of sterol accumulation in Caenorhabditis elegans: developmental requirement for 4alpha-methyl sterols.
TLDR
Non-random sterol distribution, the low concentration requirements, and the effects of 4MSs argues that sterols are unlikely to be used for bulk structural modification of cell membranes, but may be required as hormone precursors and/or developmental effectors. Expand

First Report of the Pale Cyst Nematode, Globodera pallida, in the United States.
TLDR
The morphology of cysts and second-stage juveniles and molecular analyses established the identity of the species as the pale cyst nematode Globodera pallida, a new country record for G. pallida in the United States. Expand

TLDR
Researchers of the Agricultural Research Service (ARS) of the US Department of Agriculture are actively exploring fundamental differences between the biological processes of nematodes and their host plants to lead to new chemical and non-chemical alternatives to conventional nematode control strategies.

Morphological and Molecular Identification of Globodera pallida Associated with Potato in Idaho.
The identity of a newly discovered population of pale potato cyst nematode Globodera pallida associated with potato in eastern Idaho was established by morphological and molecular methods.Expand
Fresh-market Tomato Production in a Low-input Alternative System Using Cover-crop Mulch
A low-input sustainable agricultural system for the production of staked, fresh-market field tomatoes (Lycopersicon esculentum Mill.) is described. The system uses winter annual cover crops to fix N,Expand
Caenorhabditis elegans utilizes dauer pheromone biosynthesis to dispose of toxic peroxisomal fatty acids for cellular homoeostasis.
TLDR
The results suggest that daumone biosynthesis is be an essential part of C. elegans homoeostasis, affecting survival and maintenance of optimal physiological conditions by metabolizing some of the toxic non-permissible peroxisomal VLCFAs from the worm body in the form of readily excretable daumones. Expand
Description of Globodera ellingtonae n. sp. (Nematoda: Heteroderidae) from Oregon.
TLDR
A new species of cyst nematode, Globodera ellingtonae, is described from soil collected from a field in Oregon and differs from the related species G. mexicana by its distinctive J2 tail, and by one or another of the following. Expand
