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.

Reaction of Exotic Soybean Germplasm to Phakopsora pachyrhizi in Uganda [PDF]

Plant Disease, 2008
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 deployed against them.

The Effect of Solar Irradiance on the Mortality of Phakopsora pachyrhizi Urediniospores [PDF]

Plant Disease, 2006
Soybean rust, caused by Phakopsora pachyrhizi, may be the most important foliar disease of soybean. Within the last 10 years, the fungus has moved to many new geographical locations via spread of airborne urediniospores. The objective of this study was to determine the relationship between urediniospore viability and exposure to solar radiation ...

Caracteres epidemiológicos e uso da análise de agrupamento para resistência parcial à ferrugem da soja Epidemiological characters and the use of cluster analysis for characterizing partial resistance to soybean rust

Pesquisa Agropecuária Brasileira, 2007
O objetivo deste trabalho foi avaliar a resistência parcial de genótipos de soja ao fungo Phakopsora pachyrhizi. Calcularam-se o número médio de pústulas, a severidade e a área abaixo da curva de progresso da doença.

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

Characterization of Nonhost Resistance of Arabidopsis to the Asian Soybean Rust

Molecular Plant-Microbe Interactions, 2008
Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is a devastating disease of soybean. We report the use of the nonhost plant Arabidopsis thaliana to identify the genetic basis of resistance to P. pachyrhizi. Upon attack by P.

Functional Analysis of the Asian Soybean Rust Resistance Pathway Mediated by Rpp2

Molecular Plant-Microbe Interactions, 2011
Asian soybean rust is an aggressive foliar disease caused by the obligate biotrophic fungus Phakopsora pachyrhizi. On susceptible plants, the pathogen penetrates and colonizes leaf tissue, resulting in the formation of necrotic lesions and the ...

The Importance of Phenolic Metabolism to Limit the Growth of Phakopsora pachyrhizi [PDF]

Phytopathology®, 2009
Understanding the metabolic responses of the plant to a devastating foliar disease, soybean rust, caused by Phakopsora pachyrhizi, will assist in development of cultivars resistant to soybean rust. In this study, differences in phenolic metabolism were analyzed between inoculated and noninoculated plants using two susceptible and three resistant ...
