ABA Is Required for Leptosphaeria maculans Resistance via ABI1- and ABI4-Dependent Signaling

Molecular Plant-Microbe Interactions, 2007
Abscisic acid (ABA) is a defense hormone with influence on callose-dependent and -independent resistance against Leptosphaeria maculans acting in the RLM1Col pathway.

Genetic Relationship of Brassicaceae Hybrids with Various Resistance to Blackleg Is Disclosed by the Use of Molecular Markers

Current Issues in Molecular Biology, 2022
Brassica napus is an important oil source. Its narrow gene pool can be widened by interspecific hybridization with the Brassicaceae species. One of the agronomically important traits, that can be transferred through the hybridization, is the resistance ...

Experimental dissection of phenotypic variation for quantitative disease resistance in canola (Brassica napus) – Leptosphaeria maculans interactions

Pest Management Science, EarlyView.
This graphical abstract illustrates how quantitative resistance to Leptosphaeria maculans in canola is experimentally estimated through multi‐environment replicated trials measuring crown canker severity. Genotype, environment and pathogen sources feed into phenotyping, followed by variance partitioning using mixed models and beta regression to ...

Sensitivity of winter rapeseed (Brassica napus L.) to isolates of the fungus Leptosphaeria maculans (Desm.) Ces. et de Not

Plant Protection Science, 2002
The pure cultures of the fungus Leptosphaeria maculans were isolated from the rapeseed leaves collected in Moravia. Two isolates were collected on the basis of their ability to produce yellow colour.

Decreased DMI sensitivity of Plenodomus biglobosus (phoma of oilseed rape) associated with CYP51 substitution G476S

Pest Management Science, EarlyView.
Here, we report for the first time a target site mutation in the CYP51 gene of the oilseed rape phoma stem canker fungus Plenodomus biglobosus (Leptosphaeria biglobosa) that is associated with decreased sensitivity to sterol demethylation inhibitor fungicides.

Efficacy of Blackleg Major Resistance Genes in B. napus in Germany

Pathogens, 2022
Leptosphaeria maculans is one of the major pathogens of oilseed rape (B. napus). It causes blackleg disease, which accounts for significant yield losses worldwide.

Phenotypic scoring of canola blackleg severity using machine learning image analysis

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Canola blackleg is a fungal disease that causes significant yield loss and plant death of infected canola (Brassica napus L., Brassica rapa L., Brassica juncea L.) fields worldwide. One of the most effective methods for controlling blackleg is through the cultivation of resistant varieties.

Bacterial and fungal endophyte communities in healthy and diseased oilseed rape and their potential for biocontrol of Sclerotinia and Phoma disease

Scientific Reports, 2021
Phoma stem canker (caused by the ascomycetes Leptosphaeria maculans and Leptosphaeria biglobosa) is an important disease of oilseed rape. Its effect on endophyte communities in roots and shoots and the potential of endophytes to promote growth and ...

Validating the Strategic Deployment of Blackleg Resistance Gene Groups in Commercial Canola Fields on the Canadian Prairies

Frontiers in Plant Science, 2021
Blackleg, caused by the fungal pathogen Leptosphaeria maculans, is a serious threat to canola (Brassica napus L.) production in western Canada. Crop scouting and extended crop rotation, along with the use of effective genetic resistance, have been key ...

Genetic diversity and population structure analysis of Ethiopian mustard (Brassica carinata A. Braun) accessions using simple sequence repeat markers

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Brassica carinata A. Braun is an oilseed that originated in Ethiopia with a wide range of industrial and food applications. Exploring the genetic structure of the crop is crucial for breeding and conservation measures. Despite the fairly large number of B.
