Characterizing Resistance to Phakopsora pachyrhizi in Soybean [PDF]

Plant Disease, 2011
Resistance in soybean to Phakopsora pachyrhizi, the cause of soybean rust, is characterized by either reddish-brown (RB) lesions or an immune response. The RB type of resistance can be incomplete, as evidenced by the presence of sporulating uredinia within lesions. Susceptibility, on the other hand, is exemplified by tan-colored (TAN) lesions, and can

Characteristics of fungicide resistance in Asian soybean rust (Phakopsora pachyrhizi) in Paraguay for 2022-2023: insights from genetic mutations and molecular dynamics simulations. [PDF]

Pest Manag Sci
Phakopsora pachyrhizi in Paraguay showed diverse resistance to DMI, SDHI, and QoI fungicides at both regional and intra‐field levels, likely driven by target mutation genes. Abstract BACKGROUND Phakopsora pachyrhizi, the causative agent of Asian soybean rust, poses a major threat to soybean production in South America. The rising incidence of fungicide

New insights into Phakopsora pachyrhizi infection based on transcriptome analysis in planta. [PDF]

Genet Mol Biol, 2018
Asian soybean rust (ASR) is one of the most destructive diseases affecting soybeans. The causative agent of ASR, the fungus Phakopsora pachyrhizi, presents characteristics that make it difficult to study in vitro, limiting our knowledge of plant-pathogen

Population Genomics Reveals Distinct Lineage of the Asian Soybean Rust Fungus Phakopsora pachyrhizi in the United States of America Unrelated to Brazilian Populations. [PDF]

Mol Plant Pathol
Genomic analysis identifies the US population of Asian soybean rust fungus Phakopsora pachyrhizi as genetically distinct from South American and East African isolates, offering new insights into its global diversity. ABSTRACT Asian soybean rust (ASR), caused by the obligate biotrophic fungus Phakopsora pachyrhizi, was first reported in the continental ...

In vivo sensitivity of Phakopsora pachyrhizi to fungicides [PDF]

Ciência Rural, 2019
: Asian soybean rust is one of the most destructive diseases that can be found in this crop. It can be largely controlled by fungicide application. The objective was to assess the sensitivity of P. pachyrhizi isolates to fungicides.

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.
