Molecular Characterization of Resistance to Soybean Rust (Phakopsora pachyrhizi Syd. & Syd.) in Soybean Cultivar DT 2000 (PI 635999)
Resistance to soybean rust (SBR), caused by Phakopsora pachyrhizi Syd. & Syd., has been identified in many soybean germplasm accessions and is conferred by either dominant or recessive genes that have been mapped to six independent loci (Rpp1 -Rpp6), but No U.S. cultivars are resistant to SBR. The cultivar DT 2000 (PI 635999) has resistance to P. pachyrhizi isolates and field populations from t...
متن کاملCorrelations between traits in soybean (Glycine max L.) naturally infected with Asian rust (Phakopsora pachyrhizi).
Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this study, we investigated phenotypic, genotypi...
متن کاملDevelopment of simple sequence repeat markers for the soybean rust fungus, Phakopsora pachyrhizi.
Twenty-four simple sequence repeat markers were developed for Phakopsora pachyrhizi, a fungal pathogen of soybean (Glycine max) and other legumes. All 24 of the loci were evaluated on 28 isolates of P. pachyrhizi. Twenty-one loci were polymorphic, with allelic diversity ranging from two to eight alleles, and null alleles were observed for eight of the 24 loci. A preliminary screen with the clos...
متن کاملExpressed sequence tag analysis of the soybean rust pathogen Phakopsora pachyrhizi.
Soybean rust is caused by the obligate fungal pathogen Phakopsora pachyrhizi Sydow. A unidirectional cDNA library was constructed using mRNA isolated from germinating P. pachyrhizi urediniospores to identify genes expressed at this physiological stage. Single pass sequence analysis of 908 clones revealed 488 unique expressed sequence tags (ESTs, unigenes) of which 107 appeared as multiple copie...
متن کاملProteomic analysis of germinating urediniospores of Phakopsora pachyrhizi, causal agent of Asian soybean rust.
Phakopsora pachyrhizi is an obligate pathogen that causes Asian soybean rust. Asian soybean rust has an unusually broad host range and infects by direct penetration through the leaf cuticle. In order to understand the early events in the infection process, it is important to identify and characterize proteins in P. pachyrhizi. Germination of the urediniospore is the first stage in the infection...
