Archaeophytopathology of Phakopsora pachyrhizi, the Soybean Rust Pathogen [PDF]

Plant Disease, 2015
Herbarium specimens are useful to compare attributes of the past to attributes of today and predictions into the future. In this study, herbarium specimens from 1887 to 2006 were used to identify Phakopsora pachyrhizi and P. meibomiae, the two known fungal species that cause soybean rust.

Identifying and Quantifying Phakopsora pachyrhizi Spores in Rain [PDF]

Phytopathology®, 2009
In summers of 2005 and 2006, rain was collected weekly at over 100 selected National Atmospheric Deposition Program/National Trends Network sites across the soybean-growing region of the central and eastern United States. Rain samples were screened for Phakopsora pachyrhizi (causal agent of soybean rust) DNA using a nested real-time polymerase chain ...

Variability and functional characterization of the Phakopsora pachyrhizi Egh16-like effectors. [PDF]

Genet Mol Biol
Effector proteins in Phakopsora pachyrhizi (Pp), the causative agent of Asian Soybean rust, are involved in the infection process. A previous study identified a rust effector Egh16-like family based expression profile during the interaction with soybean.

Genetic control of soybean (Glycine max) yield in the absence and presence of the Asian rust fungus (Phakopsora pachyrhizi)

Genetics and Molecular Biology, 2008
Soybean is one of the most important crops in Brazil and continuously generates demands for production technologies, such as cultivars resistant to diseases. In recent years, the Asian rust fungus (Phakopsora pachyrhizi Syd. & P.

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 ...

Virulence Diversity of Phakopsora pachyrhizi in Mexico

PhytoFrontiers, 2022
Asian soybean rust, caused by the pathogen Phakopsora pachyrhizi, is the main soybean disease in Mexico and worldwide, threatening its production. Knowledge about the virulence of Mexican rust populations (MRPs) is crucial to develop or introduce soybean

Differential Response of Common Bean Cultivars to Phakopsora pachyrhizi [PDF]

Plant Disease, 2007
Soybean rust (Phakopsora pachyrhizi) has been reported on common bean (Phaseolus vulgaris) in Asia, South Africa, and the United States. However, there is little information on the interaction of individual isolates of Phakopsora pachyrhizi with common bean germplasm.
