Growth Promotion of Rapeseed (Brassica napus L.) and Blackleg Disease (Leptosphaeria maculans) Suppression Mediated by Endophytic Bacteria

open access: yesAgronomy, 2021
Rapeseed is an important oil crop strongly dependent on high agrochemical inputs. Some pathogens, including Leptosphaeria maculans, cause blackleg disease and can drastically decrease yields.

Inhibitors of the Detoxifying Enzyme of the Phytoalexin Brassinin Based on Quinoline and Isoquinoline Scaffolds

open access: yesMolecules, 2017
The detoxification of the phytoalexin brassinin to indole-3-carboxaldehyde and S-methyl dithiocarbamate is catalyzed by brassinin oxidase (BOLm), an inducible fungal enzyme produced by the plant pathogen Leptosphaeria maculans.

Population Diversity of Leptosphaeria maculans in Australia

open access: yesInternational Journal of Biology, 2015
The fungal pathogen Leptosphaeria maculans , causal agent of blackleg disease, is a primary cause of canola ( Brassica napus ) crop loss in Australia. Expanding our knowledge of the occurrence of this pathogen in Australia will provide valuable insights into developing methods of resistance against it.

Phytotoxins, Elicitors and Other Secondary Metabolites from Phytopathogenic “Blackleg” Fungi: Structure, Phytotoxicity and Biosynthesis

open access: yesNatural Product Communications, 2009
The metabolites produced by the fungal species Leptosphaeria maculans and L. biglobosa under different culture conditions, together with their phytotoxic activities are reviewed.

Evaluation of the sensitivity of Leptosphaeria maculans isolates causing phoma stem canker in oilseed rape in the Czech Republic to boscalid and dimoxystrobin fungicides

open access: yesPlant Protection Science, 2022
Phoma stem canker, caused by Leptosphaeria spp. is generally managed with demethylation inhibitor (DMI) fungicides in the Czech Republic. However, there have been reports of resistance to DMIs in L. maculans populations.

Recognition of Avirulence Gene AvrLm1 from Hemibiotrophic Ascomycete Leptosphaeria maculans Triggers Salicylic Acid and Ethylene Signaling in Brassica napus

open access: yesMolecular Plant-Microbe Interactions, 2012
Interaction of a plant with a fungal pathogen is an encounter with hundreds of molecules. In contrast to this, a single molecule often decides between the disease and resistance.

Effect of volatile and non-volatile metabolites from Leptosphaeria maculans on tomato calli under abiotic stresses

open access: yesPlant Stress, 2022
Drought and salinity can be serious problems for agricultural productivity in certain planet areas. Leptosphaeria maculans is the causative agent of the blackleg in crucifer plants.

Frequency of avirulence alleles in field populations of Leptosphaeria maculans in Europe

open access: yesEuropean Journal of Plant Pathology, 2006
This paper describes the first large-scale Europe-wide survey of avirulence alleles and races of Leptosphaeria maculans. Isolates were collected from the spring rape cultivar Drakkar, with no known genes for resistance against L. maculans, at six experimental sites across the main oilseed rape growing regions of Europe, including the UK, Germany ...

Towards a durable management of genetic resistances toLeptosphaeria maculans [PDF]

open access: yesOléagineux, Corps gras, Lipides, 2003
Blackeg is the major disease of winter oilseed rape in France. For an efficient control of the disease several tools could be combined, but mainly plant breeding has been used to increase winter oilseed rape resistance to blackleg. A useful step was reached in the nineties, using a specific resistance gene (Rlm1).

Maculansins, Cryptic Phytotoxins from Blackleg Fungi

open access: yesNatural Product Communications, 2011
The phytotoxins and other metabolites produced by isolates L2/M2 of the fungal species Leptosphaeria maculans under different culture conditions, together with those of two new, but related isolates are disclosed.
