Investigations Into the Genetic Basis of Resistance to Brown Stem Rot in Soybean
These studies examine the inheritance of brown stem rot (BSR) resistance in soybean [Glycine max (L.) Merr.], caused by a soil-borne fungal pathogen Phialophora gregata f. sp. sojae. Three known BSR resistance genes or quantitative trait loci (QTL) have all been mapped together on linkage group …

Population Genetics and Differential Pathogenicity of the Soybean Brown Stem Rot Pathogen Phialophora Gregata
Brown stem rot (BSR) of soybean caused by the soilborne deuteromycete, Phialophora gregata, is of great importance to soybean production of the world. This study was aimed at discovering genetic variation in P. gregata from soybean and the relationship between genetic variation and pathogenicity. …

Soybean and Phialophora gregata interactions: Implications for evaluating resistance to brown stem rot of soybean
Resistance of soybean to brown stem rot (BSR), caused by Phialophora gregata (Allington and Chamberlain) W. Gams, has become an important aspect of soybean breeding programs in the north central United States. The discovery of variability of P. gregata isolates from different states has increased …

Mapping of brown stem rot resistance, genetic yield gains, and yield impact of soybean cyst nematode
Fine Mapping of Resistance Genes from Five Brown Stem Rot Resistance Sources in Soybean Brown stem rot (BSR) of soybean [Glycine max (L.) Merr.] caused by Cadophora gregata (Allington & D.W. Chamb.) T.C. Harr. & McNew, can be controlled effectively with genetic host resistance. Three BSR resistance …

Agronomic and molecular marker mapping of brown stem rot, phytophthora root rot, and powdery mildew resistance in soybean
… the yield of soybean (Glycine max (L.) Merr.). Brown stem rot of soybean, caused by Phialophora gregata (Allington and Chamberlain) W. Gams, and phytophthora root rot, caused by Phytophthora sojae Kaufmann & Gerdemann, are major diseases of soybean in Illinois. A gene for resistance to powdery …

The Advantages and Inheritance of Brown Stem Rot Resistance in Soybeans and The Implications to Breeding for Resistance (Phialophora Gregata, Disease Resistance)
Brown stem rot (BSR) is a fungal disease of soybean {Glycine max (L.) Merr.} caused by Phialophora gregata Allington and Chamberlain (W. Gams). Field and greenhouse tests were performed to study the effect of BSR resistance on soybean yield, to study the heritability and genetics of BSR resistance, …

Inheritance and Selection for Resistance to Phialophora Gregata in Soybeans
Brown stem rot (BSR) caused by Phialophora gregata (Allington and Chamberlain) W. Gams is an important disease of soybeans (Glycine max (L.) Merr.) especially in the North Central U.S. Field and greenhouse experiments were initiated to study the inheritance of BSR resistance in a soybean plant …

Transformation of Somatic Embryos of Soybean With Chitinase and Beta-1,3-Glucanase Genes via Particle Bombardment
… transgene could enhance disease resistance to brown stem rot, sudden death syndrome and brown leaf spot at the early stage of plant and disease development.

Analyses of Interactions Between Soybean and Phialophora Gregata
… and Chamberlain) W. Gams, the cause of brown stem rot (BSR) in soybean (Glycine max (L.) Merr.), is critical to prevent yield losses in the northern USA. The objective of the first phase of this study was to determine the effect of P. gregata source on aggressiveness and physiologic …

Molecular response of soybean (Glycine max (L.) Merr) to Phialophora gregata
The soybean disease Brown Stem Rot is caused by infection by the fungus Phialophora gregata. Several cultivars of soybean (Glycine max (L.) Merr.) show levels of resistance to attack by the fungus. In order to determine the mechanism of this resistance, the response of whole plants and soybean …
