Rpg1, a soybean gene effective against races of bacterial blight, maps to a cluster of previously identified disease resistance genes
It is demonstrated that Rpg1 maps to a cluster of previously identified resistance genes, including those effective against fungal, viral and nematode pathogens, including the avirulence genes avrB or avrRpm1. Expand
Tightly linked Rps12 and Rps13 genes provide broad-spectrum Phytophthora resistance in soybean
The Phytophtora root and stem rot is a serious disease in soybean. It is caused by the oomycete pathogen Phytophthora sojae. Growing Phytophthora resistant cultivars is the major method ofExpand
Integrated Management of Important Soybean Pathogens of the United States in Changing Climate
Soybean (Glycine max L.) is a major crop grown in the United States but is susceptible to many diseases that cause significant yield losses each year. Consistent threats exist across both northernExpand
Mining germplasm panels and phenotypic datasets to identify loci for resistance to Phytophthora sojae in soybean
Genetic and phenotypic dissection of these loci may lead to the characterization of novel Rps genes that can be effectively deployed in new soybean cultivars against diverse P. sojae populations. Expand
A Novel Phytophthora sojae Resistance Rps12 Gene Mapped to a Genomic Region That Contains Several Rps Genes
A novel Rps gene is named Rps12, which is expected to be an invaluable resource in breeding soybeans for Phytophthora resistance, and is mapped to a highly recombinogenic, gene-rich genomic region carrying several nucleotide binding site-leucine rich repeat (NBS-LRR)-like genes. Expand
Fine Mapping of a Resistance Gene RpsHN that Controls Phytophthora sojae Using Recombinant Inbred Lines and Secondary Populations
Real-time RT-PCR analysis of the possible candidate genes showed that three genes are likely involved in PRR resistance and will serve as a basis for cloning, transferring of resistant genes and breeding of P. sojae-resistant soybean cultivars through marker-assisted selection. Expand
Genetic characterization and fine mapping of the novel Phytophthora resistance gene in a Chinese soybean cultivar
The genetic basis of the resistance in the soybean cultivar ‘Yudou 29’ was elucidated through an inheritance study and molecular mapping, indicating that resistance in ‘ Yudou29’ is controlled by a single dominant gene. Expand
Pathogenic diversity of Phytophthora sojae and breeding strategies to develop Phytophthora-resistant soybeans
What is currently known about pathogenic races of P. sojae in the USA and Japan is reviewed, selection of sources of Rps genes or minor genes providing partial resistance, and the current state and future scope of breeding Phytophthora-resistant soybean cultivars are reviewed. Expand
A survey of soybean germplasm for resistance to Phytophthora sojae
The results of this study can be utilized to plant appropriately resistant cultivars in infected fields and to provide good breeding materials. Expand
Age-related regulation of induced isoflavonoid responses in soybean lines differing in inherent elicitation competency
Differences in glyceollin elicitation competency in Williams and Harosoy may relate more to inherent differences in the net accumulations of isoflavone precursor pools than to the generation of the elicitation competent state per se. Expand
