Studies on Soybean Sudden Death Syndrome and Its Causal Organism Fusarium Solani F. Sp. Glycines
There was no significant interaction between four isolates of F. solani f. sp. glycines and five soybean entries for foliar disease severity ratings. There were no differences in length of tap root lesions, losses in root dry-weight, and vascular stem length discoloration among the five soybean …

Resistance to Fusarium Solani F. Sp. Glycines, the Causal Organism of Sudden Death Syndrome of Soybean
Finally, the inheritance of resistance was studied in a population from a MR G. sofa line (PI 522.211 A) and susceptible cv. Spencer. The frequency distribution of the F4 family means based on foliar disease severity ratings resembled a normal distribution and the distribution of means of SIDS …

Effects of Root Characteristics and Deep Tillage on the Development of Sudden Death Syndrome in Soybean
Current research on sudden death syndrome (SDS), caused by the fungus Fusarium solani f. sp. glycines (FSG) relies on foliar severity ratings as an indication of disease resistance. However, foliar symptom severity does not always correlate well with infection on the root system or with reductions …

Effect of fungicide seed treatments on Fusarium virguliforme and development of sudden death syndrome in soybean
Sudden death syndrome (SDS) is a soilborne disease responsible for causing significant yield reductions across soybean-producing states. Recent research indicates that infection of the soybean radicle early in the season by Fusarium virguliforme (Fv), the SDS pathogen, is critical for disease …

IDENTIFICATION AND CHARACTERIZATIONS OF PATHOGENICITY GENES IN FUSARIUM VIRGULIFORME, THE CAUSAL AGENT OF SOYBEAN SUDDEN DEATH SYNDROME (SDS)
… Homma & Lattanzi), the causal agent of sudden death syndrome (SDS) of soybean (Glycine max [L.] Merrill), is responsible for major soybean yield losses in North America and South America. Despite the importance of SDS, few agronomic practices have been used to manage SDS successfully. …

IDENTIFICATIN AND CHARACTERIZATION OF PATHOGENICITY GENES IN FUSARIUM VIRGULIFORME, THE CAUSAL AGENET OF SUDDEN DEATH SYNDROME (SDS) IN SOYBEAN
… is a soil-borne pathogen that causes sudden death syndrome (SDS) disease in soybean. SDS is one of the most significant diseases of soybean in the United States. Fungal infection results in root and crown rot as well as SDS typical foliar symptoms including chlorosis, necrosis and …

Resistance of Soybean [Glycine Max (L.) Merr.] to Fusarium Solani F. Sp. Glycines: Causal Agent of Sudden Death Syndrome
The objective of my third study was to detect QTL conferring SDS resistance in two populations of recombinant inbred lines (RILs) populations. These populations were from the crosses PI 567374 x 'Omaha' and 'Ina' x LN91-1695. Six chromosomal regions were significantly associated with SDS resistance …

Application of in vitro methods to improve soybean resistance to Fusarium solani, the causal agent of sudden death syndrome
Sudden death syndrome (SDS) of soybean (Glycine max (L.) Merr.) is caused by the soilborne fungus, Fusarium solani. Calli reactions of five soybean cultivars grown on culture medium amended with fungal culture filtrate were compared to the reactions of the same five cultivars inoculated with the …

Evaluation and characterization of QTL controlling seed composition in soybean and breeding for resistance to sudden death syndrome of soybean
… in soybean and QTL conferring resistance to sudden death syndrome of soybean. In chapter 2, a genetic locus conferring pink flowers, the wp locus, and a confirmed seed protein concentration QTL located on chromosome 20 are evaluated in four genetic backgrounds for associations with the …

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 …

Identification of phytotoxins produced by fusarium virguliforme associated with foliar symptoms of sudden death syndrome and genome-wide association studies for soybean disease resistance
… Fusarium virguliforme, which causes soybean sudden death syndrome (SDS). A robust and comprehensive bioinformatics-searching pipeline was established and I successfully identified three secondary metabolites and 11 phytotoxic effectors. One of the effectors, FvNIS1, induced identical foliar …

Expression and inheritance of resistance to Fusarium solani in soybean
Sudden death syndrome (SDS) of soybean (Glycine max (L.) Merr.) is caused by the soil borne fungus Fusarium solani (Mart.) Appel & Wollenw. emend. Snyd. & Hans. Symptoms of SDS include root rot, xylem discoloration, foliar chlorosis and interveinal necrosis. Microplot, field and greenhouse …

Evaluation of resistance in Glycine max to Fusarium virguliforme and in perennial Glycine species to Phakopsora pachyrhizi and Heterodera glycines
… by FAO to reduce yield by 20 to 40% worldwide. Sudden death syndrome of soybean, soybean rust, and infection by soybean cyst nematode caused by fungal pathogens Fusarium virguliforme and Phakopsora pachyrhizi and the plant-parasitic nematode Heterodera glycines, respectively, are three major …

Evaluation of fertile lines derived from the hybridization of Glycine max and G. tomentella
… to Fusarium virguliforme, the causal agent of sudden death syndrome. Our best lines performed nearly as well the publicly available commercial cultivars, Cordell and LS94-3207, though not as well as the best check, PI 567374. Both of these traits significantly improved the disease resistance of …
