Soybean Sudden Death Syndrome Influenced by Macronutrient Fertility on Irrigated Soybean in a Corn/Soybean Rotation

Diseases of Soybean: Sudden Death Syndrome

Soybean seed protein, oil, fatty acids, and mineral composition as influenced by soybean-corn rotation

Effects of crop rotation on soybean (Glycine max (L) Merr.) seed composition have not been well investigated. Therefore, the objective of this study was to investigate the effects of soybean-corn (Zea mays L.) rotations on seed protein, oil, and fatty acids composition on soybean. Soybeans were grown at Stoneville, MS, from 2005 to 2008 in five different scheduled cropping sequences. In 2007, f...

Soybean sudden death syndrome species diversity within north and South america revealed by multilocus genotyping.

Sudden death syndrome (SDS) of soybean has become a serious constraint to the production of this crop in North and South America. Phenotypic and multilocus molecular phylogenetic analyses, as well as pathogenicity experiments, have demonstrated that four morphologically and phylogenetically distinct fusaria can induce soybean SDS. Published molecular diagnostic assays for the detection and iden...

Localized Influence of Heterodera glycines on Sudden Death Syndrome of Soybean.

Half-root tests were established to examine the association between Heterodera glycines and the blue strain of Fusarium solani, the causal agent of sudden death syndrome (SDS) of soybean. Two independent root systems were established for soybean 'Coker 156' and inoculated (half root/half root) with F. solani, H. glycines, both organisms on opposite root halves, both organisms on one root half, ...

Sexual reproduction in the soybean sudden death syndrome pathogen Fusarium tucumaniae.

We investigated the sexual reproductive mode of the two most important etiological agents of soybean sudden death syndrome, Fusarium tucumaniae and Fusarium virguliforme. F. tucumaniae sexual crosses often were highly fertile, making it possible to assign mating type and assess female fertility in 24 South American isolates. These crosses produced red perithecia and oblong-elliptical ascospores...
