Fungi Associated With Heterodera Glycines in Illinois
Populations of Heterodera glycines in two Illinois soybean fields were studied during 1983-1985. Soil samples were collected every 3-4 weeks from May-November of 1983 and from February-November of 1984-1985. Cysts of H. glycines were extracted from soil, counted, and fungi isolated. Identified …

Evaluation of Rhizoctonia solani - Heterodera glycines interactions on soybean
Rhizoctonia solani and the soybean cyst nematode (Heterodera glycines; SCN) are two soilborne pathogens that co-infest fields in soybean-producing states, contributing to significant yield reduction. Both pathogens infect the soybean radicle early in the growing season causing pre- and …

The role of heterodera glycines biotin synthase in the nematode-soybean interactions
Heterodera glycines, the soybean cyst nematode (SCN), is a plant-parasitic nematode capable of manipulating host plant biochemistry and development. Many studies have shown that the nematode has acquired genes from bacteria via horizontal gene transfer events (HGTs) that have the potential to …

Developmental biology of heterodera glycines (soybean cyst nematode) and other plant - parasitic nematodes
… Sedentary plant-parasitic nematodes (PPN) like Heterodera glycines, among the most damaging pathogens to agriculture production. The sedentary nematodes are more fecund and considered more damaging than their phylogenetically closest migratory relatives. A better understanding of their pre-hatch …

Analysis and Characterization of Vitamin B Biosynthesis Pathways in the Phytoparasitic Nematode Heterodera Glycines
The soybean cyst nematode (SCN), Heterodera glycines is an obligate plant parasite that can cause devastating crop losses. To aide in the study of this pathogen, the SCN genome and the transcriptome of second stage juveniles and eggs were shotgun sequenced. A bioinformatic screen of the data …

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 …

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
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 …

An agent-based model to simulate virus-based biocontrol for the soybean cyst nematode, Heterodera glycines
… 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 microscopic obligate endoparasite with an entirely belowground life …

Race studies and effects of soybean root leachate and herbicides on hatching and emergence of Heterodera glycines
Studies were conducted (1) to determine H. glycines egg hatch and emergence of second-stage juveniles (J2) from cysts exposed to soybean root leachate in vitro and under field conditions, (2) to determine effect of six soil-applied herbicides on hatch and emergence, (3) to clarify the distribution …

Effect of Aldicarb and Resistance on Yield Components of Soybean and Population Dynamics of Cyst Nematode (Heterodera, Illinois, Phomopsis)
… and susceptible to races three and four of Heterodera glycines were grown in three fields in Southern Illinois treated and nontreated with aldicarb and naturally infested with race three of the soybean cyst nematode. Cyst nematode reduced the height of plants primarily by reducing the …

Investigation on the North American Isolate of Pasteuria Sp., a Biological Control Agent of the Soybean Cyst Nematode, Heterodera Glycines
The research presented herein indicates that, given sufficient time following introduction into a field, Pasteuria may increase to levels that would be effective as one component in an integrated pest management program to control H. glycines.

Evaluation of resistance in Glycine max to Fusarium virguliforme and in perennial Glycine species to Phakopsora pachyrhizi and Heterodera glycines
… pachyrhizi and the plant-parasitic nematode Heterodera glycines, respectively, are three major yield-limiting problems. Soybean cultivars have a narrow genetic base due to bottlenecks in modern cultivar development. Lack of partially resistant cultivars, in the case of sudden death syndrome, …

Host-Parasite Interactions of the Soybean Cyst Nematode and Snap Beans Compared to Soybeans (Phaseolus Vulgaris, Heterodera Glycines, Max, Resistance, Temperature)
Soybean cyst nematode (SCN), (Heterodera glycines), a devastating parasite of soybean (Glycine max), was recently reported as damaging snap bean (Phaseolus vulgaris) in an Illinois commercial snap bean field. Because little information concerning the host-parasite relations of snap bean and SCN …

Effects of Heterodera Glycines Population Densities on Fusarium Solani F. Sp. Glycines Colonization of Soybean Roots and Development of Sudden Death Syndrome
Estimation of root colonization by Fsg with the plating bioassay was difficult and the results were often unsatisfactory in these experiments. Therefore, an alternative method was explored, relative quantification with real-time quantitative PCR (QPCR), to estimate fungal colonization of soybean …
