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 ...

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

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.

Occurrence of Telia of Phakopsora pachyrhizi on Kudzu in Texas

Plant Disease, 2008
The first discovery of Asian soybean rust (ASR) caused by Phakopsora pachyrhizi H. Sydow & Sydow in the continental United States was in Louisiana in 2004 (3). In Texas, the uredial stage of this fungus was first found on kudzu (Pueraria lobata) in November 2005 and 3 months later on soybean (Glycine max) (2). The telial stage of P. pachyrhizi was

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 ...

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.

First Report of Soybean Rust (Phakopsora pachyrhizi) in Nigeria

Plant Disease, 2001
Rust caused by Phakopsora pachyrhizi H. & P. Sydow was observed for the first time on soybean (Glycine max [L.] Merr.) in Nigeria during the 1999 main soybean growing season. The disease was first noticed on soybean farms in Oniyo and neighboring villages located about 20 km west of Ogbomoso (Long. 4° 02′ E and Lat.

In vivo sensitivity of Phakopsora pachyrhizi to DMI and QoI fungicides [PDF]

Summa Phytopathologica, 2015
In in vivoexperiments the sensitivity of 18 isolates of Phakopsora pachyrhizifrom several regions of Brazil to IDM fungicides (cyproconazole, epoxiconazole and tebuconazole and an IQE (pyraclostrobin) were evaluated. The assessments were based on leaflet uredia density.

Efficiency of RNAi‐based gene silencing in fungi: a meta‐analysis

New Phytologist, EarlyView.
Mechanistic interpretation of RNAi efficiency across fungal lifestyles and delivery strategies based on the present meta‐analysis. Summary RNA interference (RNAi) shows great potential to protect crops against fungal diseases, yet reported protection efficiencies vary greatly, and our understanding of the factors responsible for this variance remains ...
