Pathogenic Variation ofPhakopsora pachyrhiziInfecting Soybean in Nigeria [PDF]

Phytopathology®, 2009
Soybean rust, caused by Phakopsora pachyrhizi, is an important disease in Nigeria and many other soybean-producing countries worldwide. To determine the geographical distribution of soybean rust in Nigeria, soybean fields were surveyed in the Derived Savanna (DS), Northern Guinea Savanna (NGS), and Southern Guinea Savanna (SGS) agroecological zones in ...

An Immunofluorescence Assay to Detect Urediniospores of Phakopsora pachyrhizi [PDF]

Plant Disease, 2008
An indirect immunofluorescence spore assay (IFSA) was developed to detect urediniospores of Phakopsora pachyrhizi, utilizing rabbit polyclonal antisera produced in response to intact nongerminated (SBR1A) or germinated (SBR2) urediniospores of P. pachyrhizi. Both antisera were specific to Phakopsora spp.
