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.

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 ...

Comparative genomics reveals lineage‐associated structural variation and diversification in a barley fungal pathogen

New Phytologist, EarlyView.
Genome‐wide copy‐number variation landscape highlights structural divergence across Puccinia hordei isolates and potentially links Cyp51 amplification to fungicide insensitivity. Summary Leaf rust, caused by Puccinia hordei, is a major barley disease worldwide.

Cytokinin Metabolism of Pathogenic Fungus Leptosphaeria maculans Involves Isopentenyltransferase, Adenosine Kinase and Cytokinin Oxidase/Dehydrogenase

Frontiers in Microbiology, 2017
Among phytohormones, cytokinins (CKs) play an important role in controlling crucial aspects of plant development. Not only plants but also diverse microorganisms are able to produce phytohormones, including CKs, though knowledge concerning their ...

Survival of A-group and B-group Leptosphaeria maculans (phoma stem canker) ascospores in air and mycelium on oilseed rape stem debris

, 2003
Mycelium of Leptosphaeria maculans survived on oilseed rape stem base debris buried in sand for 2, 4, 6, 8, 10 or 12 months and produced pseudothecia after subsequent exposure on the surface of the ground under natural conditions for 2-4 months, but did ...

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.

The receptor-like kinase SOBIR1 interacts with Brassica napus LepR3 and is required for Leptosphaeria maculans AvrLm1-triggered immunity

Frontiers in Plant Science, 2015
The fungus Leptosphaeria maculans (L. maculans) is the causal agent of blackleg disease of canola/oilseed rape (Brassica napus) worldwide. We previously reported cloning of the B.

Resistance to Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape) induced by L. biglobosa and chemical defence activators in field and controlled environments

, 2006
Effects of pretreatment of Brassica napus leaves with ascospores of Leptosphaeria biglobosa or chemical defence activators [acibenzolar-S-methyl (ASM) or menadione sodium bisulphite (MSB)] on infection by ascospores of Leptosphaeria maculans (phoma stem ...

Colonization of winter oilseed rape tissues by A/Tox+ and B/Tox0 Leptosphaeria maculans (phoma stem canker) in France and England [PDF]

, 2002
The colonization of winter oilseed rape plants and epidemiology of phoma stem canker differed between A/Tox(+) and B /Tox(0) Leptosphaeria maculans. In France and England, where plant colonization was investigated during two and three growing seasons ...
