The LmSNF1 gene is required for pathogenicity in the canola blackleg pathogen Leptosphaeria maculans. [PDF]
PLoS ONE, 2014 Leptosphaeria maculans is a fungal pathogen causing blackleg in canola. Its virulence has been attributed, among other factors, to the activity of hydrolytic cell wall degrading enzymes (CWDEs).

Blackleg Yield Losses and Interactions with Verticillium Stripe in Canola (Brassica napus) in Canada
Plants, 2023 Blackleg, caused by Leptosphaeria maculans, is an important disease of canola (Brassica napus). The pathogen can attack stems, leaves and pods, but basal stem cankers are most damaging and can result in significant yield losses.

Decreased Sensitivity of Leptosphaeria maculans to Pyraclostrobin in Alberta, Canada [PDF]
Plant Disease, 2020 Leptosphaeria maculans, the causal agent of blackleg of canola (Brassica napus), can be managed with pyraclostrobin and other strobilurin fungicides. Their frequent application, however, poses a risk for the development of insensitivity in fungal populations. A collection of L.

Pest Management Science, EarlyView.This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Salt Stress Induces Production of Melanin Related Metabolites in the Phytopathogenic Fungus
Natural Product Communications, 2009 A search for stress metabolites produced by the plant pathogenic fungus Leptosphaeria maculans (asexual stage Phoma lingam ) cultured in high salt medium led to the isolation and structure elucidation of two metabolites associated with melanin ...

Pest Management Science, EarlyView.As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

Pest Management Science, EarlyView.Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Characterization of sirodesmins isolated from the phytopathogenic fungus Leptosphaeria maculans [PDF]
Journal of the Serbian Chemical Society, 2012 Pathogenicity of phytopathogenic fungi is accociated with phytotoxins, especially with their chemical nature and quantity. Sirodesmins are phytotoxins from epipolythiodioxopiperazines group, produced by fungi Leptosphaeria maculans that is a cause of ...
