A loop-mediated isothermal amplification assay for the rapid diagnosis of soybean rust caused by Phakopsora pachyrhizi

Phytopathology Research, 2023
Soybean rust caused by the fungus Phakopsora pachyrhizi is one of the most destructive diseases to soybean production worldwide. For the rapid diagnosis and the control of soybean rust, we developed a loop-mediated isothermal amplification (LAMP) assay ...

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.

An Immunofluorescence Assay to Detect Urediniospores of Phakopsora pachyrhizi [PDF]

Plant Disease, 2008
An indirect immunofluorescence spore assay (IFSA) was developed to detect urediniospores of Phakopsora pachyrhizi, utilizing rabbit polyclonal antisera produced in response to intact nongerminated (SBR1A) or germinated (SBR2) urediniospores of P. pachyrhizi. Both antisera were specific to Phakopsora spp.

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 ...

Distribuição e identificação de Phakopsora pachyrhizi, agente causal da ferrugem da soja no estado de Minas Gerais Identification and distribution of Phakopsora pachyrhizi causal agente of the Asian rust in the Minas Gerais State

Ciência e Agrotecnologia, 2007
A ferrugem da soja é causada por duas espécies: Phakopsora pachyrhizi e P. meibomiae. No Brasil, a doença tem sido responsável por grandes perdas dessa leguminosa nas últimas safras.

Population structure and genetic diversity of Phakopsora pachyrhizi in the Southeastern United States. [PDF]

G3 (Bethesda)
Abstract Phakopsora pachyrhizi, the causal agent of soybean rust disease (SBR) on Glycine max (soybean), is considered one of the most globally devastating diseases of soybeans and is a particular problem in Brazil, China, Sub-Saharan Africa, and the southern United States.

Preservation of Phakopsora pachyrhizi Uredospores [PDF]

Journal of Phytopathology, 2007
AbstractThis study compared different temperatures and dormancy‐reversion procedures for preservation of Phakopsora pachyrhizi uredospores. The storage temperatures tested were room temperature, 5°C, −20°C and −80°C. Dehydrated and non‐dehydrated uredospores were used, and evaluations for germination (%) and infectivity (no.

Comparative Susceptibilities of Legume Species to Infection by Phakopsora pachyrhizi [PDF]

Plant Disease, 2008
Knowledge of the host range of Phakopsora pachyrhizi is important to agriculture in the United States because of the distinct possibility that economic losses could occur to crops other than soybean. Furthermore, it is possible that alternative hosts could provide a means of overwintering of the pathogen, providing inoculum to initiate epidemics in ...
