Automated soybean cyst nematode extraction unit
The soybean cyst nematode (SCN) is a plant parasitic roundworm of soybeans responsible for an estimated $0.7-1.2 billion reduction in annual yield loss. In order to manage yield loss due to SCN, soybean producers employ a nematode management plan which utilize extensive soil sampling to assess SCN …

Molecular characterization of CLE peptide mimicry during cyst nematode pathogenesis
… AT AUTHOR'S REQUEST.] Plant-parasitic cyst nematodes establish intimate parasitic relationships with their hosts by penetrating the root as motile juveniles and migrating intracellularly until they reach the root vasculature where they select a single cell to initiate a feeding site …

Inheritance of Resistance to Tobacco Cyst Nematode Globodera tabacum solanacearum
The tobacco cyst nematode [Globodera tabacum solanacearum (Miller & Gray, 1972) Behrens, 1975] is an important pathogen affecting flue-cured tobacco (Nicotiana tabacum L.) in Virginia, North Carolina, and Maryland. The resistant cultivars Coker 371 Gold and Kutsaga 110 were evaluated during 1999 …

Effects of Cereal Cyst Nematode Infection on Resistant and Susceptible Barley
Cereal cyst nematodes (CCN) are obligate biotrophs that affect the yield of cereals including barley. This parasite is one of the biotic factors that affect plant-water relations and imposes early stress that reduces yield irrespective of the availability of water and nutrient. Invasion, migration, …

Developmental biology of heterodera glycines (soybean cyst nematode) and other plant - parasitic nematodes
Nematodes are unsegmented round worms with a pseudocoelomate body cavity. Nematodes are omnipresent in nature. Most are free-living, living as bacterial or fungal feeders, while many nematodes species are parasitic to animals or plants and have a huge impact on human health and agriculture …

Identification and genetic characterization of tobacco accessions possessing resistance to tobacco cyst nematode
… tobacco cultivar with high resistance to tobacco cyst nematode (TCN) is an important initiative in the Southern Piedmont of Virginia, where this pathogen causes severe yield losses. One hundred twenty eight lines representing a diverse geographic array of tobacco accessions, including cultivars …

Soybean Cyst Nematode, Heterodera Glycines, Resistance Genes in PI 89772 and PI 209332 Soybean
Soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is the most serious disease of soybean, Glycine max (L.) Merr., in the United States. Crop rotation plays an important role in controlling the nematode. Control also utilizes different cropping systems and resistant soybean cultivars to …

Determination of soybean cultivar resistance to soybean cyst nematode with quantitative polymerase chain reaction
Heterodera glycines, the soybean cyst nematode, is the major pathogen of Glycine max (soybean). Effective management of this pathogen is contingent on the use of resistant cultivars, thus screening for resistant cultivars is essential. The purpose of this research was to develop a method to assess …

Management strategies for control of soybean cyst nematode and their effect on the nematode community
Soybean cyst nematode (SCN), Heterodera glycines, is the major yield-limiting pathogen on soybean and various plant-parasitic nematodes can damage corn. Additionally, the nematode community is a useful bioindicator for soil health. In chapter 1, relevant research is reviewed. Chapter 2 describes …

Distribution and Characterization of the Soybean Cyst Nematode, Heterodera glycines (HG) Types in South Dakota
<p>The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is an endoparasitic nematode and one of the major pests of soybean (Glycine max L.) in the United State and all over the world where soybean is grown. SCN is ranked first among the biological factors that cause yield loss in soybean. …

Characterization of horizontally transferred vitamin B biosynthesis genes in the soybean cyst nematode, Heterodera glycines
… (H. glycines), commonly known as the soybean cyst nematode (SCN), is an obligate plant parasite and a major pest of soybean. It is highly adapted to manipulate and parasitize host plants. It possesses parasitism/effector genes that enable it to developmentally alter host cells and establish …

An agent-based model to simulate virus-based biocontrol for the soybean cyst nematode, Heterodera glycines
Plant parasitic nematodes are responsible for food losses worth 78 billion dollars worldwide. The damage caused by Heterodera glycines, or soybean cyst nematode (SCN), to the US soybean crop is estimated up to 2 billion dollars annually making it the most destructive soybean pathogen. SCN is a …
