Genome scans for selection signatures identify candidate virulence genes for adaptation of the soybean cyst nematode to host resistance

Molecular Ecology
Plant pathogens are constantly under selection pressure for host resistance adaptation. Soybean cyst nematode (SCN, Heterodera glycines) is a major pest of soybean primarily managed through resistant cultivars; however, SCN populations have evolved ...

Weeds Hosting the Soybean Cyst Nematode (Heterodera glycines Ichinohe): Management Implications in Agroecological Systems

Agronomy, 2021
The soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is a major soybean-yield-limiting soil-borne pathogen, especially in the Midwestern US. Weed management is recommended for SCN integrated management, since some weed species have been reported

Soybean Cyst Nematode Resistant Soybean Trial

, 2007
Soybean cyst nematode (SCN) was identified in Iowa less than 30 years ago and is now recognized as a major pest of soybeans, particularly in sandy soil regions such as the Muscatine Island. Effective management has relied on crop rotation and the use of resistant varieties. Recently, some SCN resistant varieties have not been performing to expectations

DNA barcoding evidence for the North American presence of alfalfa cyst nematode, Heterodera medicaginis

Journal of Nematology, 2019
Specimens of Heterodera have been collected from alfalfa fields in Kearny County, Kansas & Carbon County, Montana. DNA barcoding with the COI mitochondrial gene indicate that the species is not Heterodera glycines, soybean cyst nematode, H.

Soybean cyst nematode culture collections and field populations from North Carolina and Missouri reveal high incidences of infection by viruses.

PLoS ONE, 2017
Five viruses were previously discovered infecting soybean cyst nematodes (SCN; Heterodera glycines) from greenhouse cultures maintained in Illinois. In this study, the five viruses [ScNV, ScPV, ScRV, ScTV, and SbCNV-5] were detected within SCN greenhouse

Robotic agricultural instrument for automated extraction of nematode cysts and eggs from soil to improve integrated pest management

Scientific Reports, 2021
Soybeans are an important crop for global food security. Every year, soybean yields are reduced by numerous soybean diseases, particularly the soybean cyst nematode (SCN).

Identification of Heterodera glycines (Tylenchida; Heteroderidae) Using qPCR

The Plant Pathology Journal, 2019
The soybean cyst nematode, Heterodera glycines, is a major plant-parasitic nematode that has caused important economic losses to Korea's soybean production. Four species of cyst nematodes, H. schachtii, H. glycines, H. trifolii, and H.

Second Edition of Soybean Cyst Nematode Field Guide Available [PDF]

, 2012
The soybean cyst nematode (SCN) is a major yield-limiting pathogen of soybeans in Iowa. The nematode was particularly damaging in the 2012 growing season because of the drought conditions.

Productivity Growth from Genetic Improvement: Evidence from Illinois Soybean Trial Data

American Journal of Agricultural Economics, EarlyView.
Abstract In 2023, the United States produced 28% of the world's soybeans, making understanding yield trends in the United States important for understanding global price trends. We estimate yield growth due to genetic change in soybeans using Illinois variety trial data with a modified approach.
