Genomic evidence for genes encoding leucine-rich repeat receptors linked to resistance against the eukaryotic extra- and intracellular Brassica napus pathogens Leptosphaeria maculans and Plasmodiophora brassicae. [PDF]

PLoS ONE, 2018
Genes coding for nucleotide-binding leucine-rich repeat (LRR) receptors (NLRs) control resistance against intracellular (cell-penetrating) pathogens.

Switchgrass Steroidal Saponins Reduce Fungal Disease but Decrease Yeast Fermentation Yield

GCB Bioenergy, Volume 18, Issue 1, January 2026.
Yeast fermentation of switchgrass biomass is inhibited for certain genotypes, especially those with high concentrations of steroidal saponins that protect against fungal disease. Inhibition can be reversed through (1) ergosterol addition, (2) fermentation with the bacterium Zymonomas mobilis, or (3) in different collection years.

Baseline Sensitivity of Leptosphaeria maculans to Succinate Dehydrogenase Inhibitor (SDHI) Fungicides and Development of Molecular Markers for Future Monitoring

Agriculture
Succinate dehydrogenase inhibitor (SDHI) fungicides are widely used in Australia for the control of blackleg disease (caused by Leptosphaeria maculans, also called Plenodomus lingam). Populations of L.

Introgression of Resistance Against Leptosphaeria maculans From Brassica juncea Into Brassica napus

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Introgression of blackleg‐specific resistance genes from Brassica juncea into B. napus was conducted. Genotyping/phenotyping found this material may contain previously uncharacterised resistance against the blackleg pathogen. ABSTRACT Blackleg disease is caused by the fungal plant pathogen Leptosphaeria maculans.

Introgression of Leptosphaeria maculans Resistance From Hexaploid Brassica Into Brassica napus

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Blackleg resistance was introgressed from resistant hexaploid Brassica. Phenotyping and genotyping was conducted to determine the presence of known resistance genes. The absence of resistance following phenotyping and genotyping suggests that novel resistance may have been introgressed from hexaploid Brassica.

Natural Pesticides in Crop Protection: Comparative Advantages, Ecological Risks, and Future Directions

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Although synthetic pesticides have long been used to protect crops, their widespread use has led to significant health and environmental problems, including ecological contamination, resistant pest populations, and hazardous residues in food. These restrictions have sparked interest in natural pesticides (NPs), particularly the secondary metabolites of

Isolation and Characterization of Extracellular Vesicles From Ascochyta rabiei, a Necrotrophic Fungal Chickpea Pathogen

PROTEOMICS, Volume 25, Issue 23, Page 16-36, December 2025.
ABSTRACT Extracellular vesicles produced by pathogenic organisms play a role in host recognition and invasion across kingdoms, including fungi interacting with their plant hosts. Little is known about EVs from phytopathogenic fungi compared to human fungal pathogens.

Constitutive Expression of Pea Defense Gene DRR206 Confers Resistance to Blackleg (Leptosphaeria maculans) Disease in Transgenic Canola (Brassica napus)

Molecular Plant-Microbe Interactions, 1999
To identify genes effective against the blackleg fungus Leptosphaeria maculans (Phoma lingam), we have transformed canola (Brassica napus) with four pea (Pisum sativum) genes under constitutive control by the cauliflower mosaic virus 35S promoter: PR10.1,

Assessing quantitative resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape) in young plants.

PLoS ONE, 2014
Quantitative resistance against Leptosphaeria maculans in Brassica napus is difficult to assess in young plants due to the long period of symptomless growth of the pathogen from the appearance of leaf lesions to the appearance of canker symptoms on the ...

Single R gene introgression lines for accurate dissection of the Brassica - Leptosphaeria pathosystem

Frontiers in Plant Science, 2016
Seven blackleg resistance (R) genes (Rlm1, Rlm2, Rlm3, Rlm4, LepR1, LepR2 & LepR3) were each introgressed into a common susceptible B. napus doubled-haploid (DH) line through reciprocal back-crossing, producing single-R gene introgression lines (ILs) for
