Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is now established in all major soybean-producing countries. Currently, there is little information about the molecular basis of ASR-soybean interactions, which will be needed to assist future efforts to develop effective resistance. Toward this end, abundance changes of soybean mRNAs were measured over a 7-day ASR infection time course...

Haustoria of biotrophic rust fungi are responsible for the uptake of nutrients from their hosts and for the production of secreted proteins, known as effectors, which modulate the host immune system. The identification of the transcriptome of haustoria and an understanding of the functions of expressed genes therefore hold essential keys for the elucidation of fungus-plant interactions and the ...

The rust fungi (order: Pucciniales) are a group of widely distributed fungal plant pathogens, which can infect representatives of all vascular plant groups. Rust diseases significantly impact several crop species and considerable research focuses on understanding the basis of host specificity and nonhost resistance. Like many pathogens, rust fungi vary considerably in the number of hosts they c...

Surveying invasive species can be highly resource intensive, yet near-real-time evaluations of invasion progress are important resources for management planning. In the case of the soybean rust invasion of the United States, a linked monitoring, prediction, and communication network saved U.S. soybean growers approximately $200 M/yr. Modeling of future movement of the pathogen (Phakopsora pachy...

Abstract Soybean rust caused by the fungus Phakopsora pachyrhizi is one of most destructive diseases to soybean production worldwide. For rapid diagnosis and control rust, we developed a loop-mediated isothermal amplification (LAMP) assay that targets P . -specific gene ( Phapa_6409908 ) identified from comparative genomic analysis 61 Pucciniomycotina strains. Using set screened primers optimiz...

ABSTRACT Soybean crops grown in the plains of eastern Colombia have been affected by incidence rust. This disease, still officially regarded as American soybean rust (caused Phakopsora meibomiae) Colombian Department Agriculture (ICA), causes serious damage to growing areas. Symptoms rust, such reddish-brown lesions, observed since 2004 upper half plants during vegetative stages. In 2005 and 20...
