Quantitative Resistance to Quinone Outside Inhibitor (QoI) Fungicides in Puccinia horiana Through the Combination of Seven Distinct Substitutions in Cytochrome b

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Puccinia horiana, the causal agent of chrysanthemum white rust, has developed quantitative resistance to QoI fungicides through one to four substitutions, selected from F90I, N256S, Y257N, L275F, F278L, M295V or L299F in cytochrome b (Cytb). ABSTRACT Quinone outside inhibitors (QoIs) are a major class of agricultural fungicides.

New Legume Hosts of Phakopsora pachyrhizi Based on Greenhouse Evaluations [PDF]

Plant Disease, 2008
Phakopsora pachyrhizi, the causal organism of soybean rust, was first found in the continental United States in 2004 and has been found on soybean, kudzu, Florida beggarweed, and three Phaseolus species in the field. The pathogen has been reported to occur on more than 90 legume species worldwide and it is likely to infect native and introduced legume

Quantifying ENSO‐Mediated Shifts in Soybean Rust Impact: Yield Loss Dynamics and Management Implications in Brazil

Plant Pathology, Volume 74, Issue 9, Page 2980-2988, December 2025.
Meta‐analysis of 417 trials shows that El Niño amplifies soybean rust impacts in Brazil. Damage coefficients were higher during El Niño, causing greater yield losses at similar severity, whereas yield protection from management was also greatest, emphasising the value of El Niño‐informed disease outlooks.

Combinatorially Selected Peptides for Protection of Soybean Against Phakopsora pachyrhizi [PDF]

Phytopathology®, 2010
Phakopsora pachyrhizi, the fungal pathogen that causes Asian soybean rust, has the potential to cause significant losses in soybean yield in many production regions of the United States. Germplasm with durable, single-gene resistance is lacking, and control of rust depends on timely application of fungicides.

Use of AFLP markers to estimate molecular diversity of Phakopsora pachyrhizi

Electronic Journal of Biotechnology, 2015
Background: Asian soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. & Syd., is one of the main diseases affecting soybean and has been reported as one of the most economically important fungal pathogens worldwide. Knowledge of the genetic diversity

Transcriptome Profiling of Resistance Gene Analogs in Soybean's Cross‐Tolerance to Water Limitation and Rust Stress

Food and Energy Security, Volume 14, Issue 5, September/October 2025.
ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is the most destructive foliar disease of soybean, with yield losses up to 90%. With climate change intensifying drought and expanding disease incidence, it is critical to understand how combined abiotic and biotic stresses influence plant defense.

First Report of Phakopsora pachyrhizi on Soybean in Costa Rica

Plant Disease, 2015
Phakopsora meibomiae (Arthur) Arthur has been reported to occur in several legume species in the tropical regions of Central and South America. In Costa Rica, this pathogen was initially reported as P. pachyrhizi Sydow (1); however, to our knowledge, P. pachyrhizi has not been detected in Costa Rica.

Winter Survival of the Soybean Rust Pathogen, Phakopsora pachyrhizi, in Florida [PDF]

Plant Disease, 2008
Soybean rust (SBR) survival and host availability (kudzu, Pueraria spp.) were assessed from November 2006 through April 2007 at six sites from the panhandle to southwest Florida. Micro loggers recorded both temperature and relative humidity hourly at each location.

Non‐coding RNAs in plant stress responses: molecular insights and agricultural applications

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3195-3233, August 2025.
Summary Non‐coding RNAs (ncRNAs) have emerged as crucial regulators in plant responses to environmental stress, orchestrating complex networks that finetune gene expression under both abiotic and biotic challenges. To elucidate this intricate ncRNA crosstalk, this review comprehensively summarizes recent advances in understanding the mechanisms of key ...

Prospects for Durable Resistance Against an Old Soybean Enemy: A Four-Decade Journey from Rpp1 (Resistance to Phakopsora pachyrhizi) to Rpp7

Agronomy, 2019
Soybean rust (SBR), caused by Phakopsora spp., is a major global concern for soybean producers. SBR causing fungi are polycyclic and obligate biotrophs, rendering the study of their biology particularly tedious.
