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 ...

Soybean Rust Resistance and Yield Performance of Elite Soybean Genotypes Across Diverse Environments in Uganda. [PDF]

Plant Environ Interact
ABSTRACT Soybean (Glycine max (L.) Merr.) is one of the important legumes globally, serving as an affordable and valuable protein source for humans and livestock. However, selecting the most suitable genotype across diverse environmental conditions remains a major challenge due to significant genotype‐by‐environment interactions (GEI). In addition, the

Fighting Asian soybean rust

Frontiers in Plant Science, 2016
Phakopsora pachyrhizi is a biotrophic fungus provoking Asian soybean rust (SBR) disease. SBR poses a major threat to global soybean production. Though several resistance genes provided soybean immunity to certain P. pachyrhizi races, the pathogen swiftly

Germinação de Phakopsora pachyrhizi Sid. & P. Sid. sob diferentes herbicidas [PDF]

Arquivos do Instituto Biológico, 2012
Herbicidas são bastante utilizados na agricultura para controle de plantas daninhas. Por serem aplicados sobre as plantas, além de exercerem ação sobre o organismo alvo, podem influenciar outros processos ou a interação da planta, predispondo ou reduzindo a suscetibilidade a doenças.

Characteristics of superior soybean breeding lines tolerance to rust (Phakopsora pachyrhizi Syd.)

Biosaintifika: Journal of Biology & Biology Education, 2016
Soybean rust caused by Phakopsora pachyrhizi is one of the most important diseases which limits soybean production. The aim of this study was to evaluate the resistance of 28 superior soybean lines and their tolerance to rust.

Differential expression of four soybean bZIP genes during Phakopsora pachyrhizi infection [PDF]

Functional & Integrative Genomics, 2015
Asian soybean rust (ASR), caused by the obligate biotrophic fungus Phakopsora pachyrhizi, is one of most important diseases in the soybean (Glycine max (L.) Merr.) agribusiness. The identification and characterization of genes related to plant defense responses to fungal infection are essential to develop ASR-resistant plants. In this work, we describe

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.

Advances on molecular studies of the interaction soybean - Asian rust. [PDF]

, 2012
: Effective management practices are essential for controlling rust outbreaks. The main control method used is the application of fungicides, which increases substantially the cost of production and is harmful to the environment.
