TL;DR: The study verified the presence and ability to detect all known major genes for resistance to soybean rust in the original sources of resistance, and demonstrated that soybean lines derived from the original PI sources, and presumed to possess the resistance genes, in actuality may lack the gene or express an intermediate reaction to the rust pathogen.
Journal ArticleDOI

Ranajit Bandyopadhyay,Peter S. Ojiambo,M. Twizeyimana,B. Asafo-Adjei,Reid D. Frederick,Kerry F. Pedley,C. L. Stone,Glen L. Hartman +7 more
TL;DR: The PCR assay, alignment of ITS region 2, morphological characters of the isolates, and pathogenicity tests demonstrate that P. pachyrhizi occurs in Ghana, to the authors' knowledge, this is the first report of P. PachyrHizi in Ghana.
Journal ArticleDOI
First Report of Rust Caused by Phakopsora pachyrhizi on Soybean in Democratic Republic of Congo
Peter S. Ojiambo,Ranajit Bandyopadhyay,M. Twizeyimana,A. Lema,Reid D. Frederick,Kerry F. Pedley,C. L. Stone,Glen L. Hartman +7 more
TL;DR: The PCR assay, morphological characters of the isolates, and pathogenicity tests demonstrate that P. pachyrhizi occurs in DRC, and it is confirmed that soybean rust caused by Phakopsora pachyrsizi is present in the country.
Journal ArticleDOI
First report of phakopsora pachyrhizi on soybean in costa rica
TL;DR: To the best of the knowledge, this is the first known confirmation of soybean rust, caused by P. pachyrhizi in Costa Rica, which is the only soybean variety bred in the country as well as one of the very few varieties available for growers.
