Identification of Quantitative Trait Loci Contributing Partial Resistance to Canadian Isolates of Aphanomyces euteiches in a Pea RIL Population Derived From a New Resistance Source

Plant Pathology, Volume 75, Issue 1, January/February 2026.
We examined Aphanomyces root rot resistance in pea accession No. 9292 and identified a major locus on chromosome 4 conferring resistance to two Canadian isolates of Aphanomyces euteiches. This locus represents a valuable target for breeding pea cultivars with durable resistance, particularly for production in western Canada.

Spatial Distribution of Aphanomyces cochlioides and Root Rot in Sugar Beet Fields [PDF]

Plant Disease, 2002
Spatial distribution of Aphanomyces cochlioides inoculum and disease was assessed in sugar beet fields located near Moorhead, MN and Wahpeton, ND. Soil samples were collected in June and July 1994 from two main plots (60 by 60 m) in each field. Samples were evaluated for A. cochlioides using a sugar beet seedling assay in the greenhouse to determine a

Comparative Genome-Wide-Association Mapping Identifies Common Loci Controlling Root System Architecture and Resistance to Aphanomyces euteiches in Pea

Frontiers in Plant Science, 2018
Combining plant genetic resistance with architectural traits that are unfavorable to disease development is a promising strategy for reducing epidemics.

Soil‐borne fungal diseases in Aotearoa New Zealand pastures: a significant research blind spot

New Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1288-1310, December 2025.
ABSTRACT In Aotearoa New Zealand (AoNZ), where pastoral agriculture is vital to the economy, reports of pasture plant species failing to persist in long‐term pastures, particularly in northern regions, are increasingly common. The underlying cause of this decline in pasture persistence remains elusive.

Identification and Functional Characterization of Isoflavone synthase Gene Family in Pea (Pisum sativum): The Entry Point to Pisatin Biosynthesis

Legume Science
Isoflavone synthase (IFS), a cytochrome P450 monooxygenase of the CYP93C subfamily, catalyzes the conversion of flavanones into isoflavones, the first committed step in the biosynthesis of isoflavonoid phytoalexins.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

Biological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Partial Resistance of Medicago truncatula to Aphanomyces euteiches Is Associated with Protection of the Root Stele and Is Controlled by a Major QTL Rich in Proteasome-Related Genes

Molecular Plant-Microbe Interactions, 2009
A pathosystem between Aphanomyces euteiches, the causal agent of pea root rot disease, and the model legume Medicago truncatula was developed to gain insights into mechanisms involved in resistance to this oomycete.

Assessment of beet leaf yellowing virus tolerance based on leaf yellowing in sugar beet

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Sugar beet (Beta vulgaris) production in Japan faces major challenges from virus yellows (VY), caused by beet leaf yellowing virus (BLYV) and transmitted by aphids. Outbreaks have reduced sugar yields, and breeding for tolerant varieties has not been conducted in Japan. This study marks the first step toward developing VY‐tolerant varieties by

Non‐Invasive Monitoring of Tetracapsuloides bryosalmonae by eDNA: Influencing Environmental Parameters

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated influencing environmental factors on a previously developed eDNA‐based detection protocol for T. bryosalmonae. Specifically, water and air temperature, precipitation as well as bryozon presence and infection status were evaluated. Recommendations for a future eDNA‐based monitoring of T. bryosalmonae are provided.

Interspecific Interactions and Host Background Influence the Population Dynamics of the Species Causing the Ascochyta Blight Complex in Pea

Plant Pathology, Volume 74, Issue 6, Page 1878-1890, August 2025.
The three Ascochyta species interact with mutualism and competition relationships; the mutualistic interaction allowed Didymella pisi to grow in a previously immune cultivar, and the competition made D. pinodes more aggressive. ABSTRACT Ascochyta blight (AB) is an important seed‐borne and foliar disease of field peas and is widely recognised as a major
