Pathogenic variation of Phakopsora pachyrhizi populations in Brazil.

open access: yes, 2018
The obligate basidiomycete Phakopsora pachyrhizi is the causal agent of soybean rust that has potential to reduce the yield of soybean drastically. Soybean production in Brazil has been threatened by the rust since the pathogen was first discovered in ...

Reaction of exotic soybean germplasm to Phakopsora pachyrhizi in Uganda

open access: yes
Host plant resistance is the best long-term strategy for managing soybean rust (Phakopsora pachyrhizi) in endemic areas. Resistance breeding efforts are hampered by the presence of several races of the pathogen that often overcome single resistance genes

Genetic structure and diversity of Phakopsora pachyrhizi isolates from soyabean

open access: yes, 2017
Simple sequence repeat (SSR) markers were used to classify 116 isolates of Phakopsora pachyrhizi, the cause of soyabean rust, collected from infected soyabean leaves in four agroecological zones in Nigeria. A high degree of genetic variation was observed
