Sterol composition of mycelia of the plant pathogenic ascomycete Leptosphaeria maculans

Phytochemistry, 2003
Analysis of sterols in mycelia of the ascomycete, Leptosphaeria maculans by gas chromatography-mass spectrometry revealed that ergosterol comprised 95% of the total sterols, with eight other sterols comprising the remaining 5%. Six of these latter sterols were putative precursors of ergosterol and their presence suggested a pathway for ergosterol ...

Resistance of leaves of Brassica species to Leptosphaeria maculans

Transactions of the British Mycological Society, 1987
Under controlled conditions, the range of responses in Brassica napusssp. oleiferaand its two putative parents, B. rapa and B. oleracea, were tested by inoculating leaves with a mixture of eight isolates or two separate isolates of Leptosphaeria maculons.

Metabolism and Metabolites of Dithiocarbamates in the Plant Pathogenic Fungus Leptosphaeria maculans

Journal of Agricultural and Food Chemistry, 2012
Synthetic compounds containing a dithiocarbamate group are known to have a variety of biological effects and applications including antifungal, herbicidal, and insecticidal application. Leptosphaeria maculans is a fungal pathogen of crucifers able to detoxify efficiently the only plant natural product containing a dithiocarbamate group, the ...

Characterization of an opsin gene from the ascomycete Leptosphaeria maculans

Genome, 2001
An opsin gene (ops) has been characterized from Leptosphaeria maculans, the ascomycete that causes blackleg disease of Brassica species. This is the second opsin identified outside the archaeal and animal kingdoms. The gene encodes a predicted protein with high similarity (70.3%) and identity (53.3%) to the nop-1 opsin of another ascomycete Neurospora

Characterisation of a cyanide hydratase gene in the phytopathogenic fungus Leptosphaeria maculans

Molecular and General Genetics MGG, 2000
A gene encoding a cyanide hydratase was cloned from an aggressive isolate of Leptosphaeria maculans, the fungus which causes blackleg disease of oilseed Brassica spp. This enzyme catalyses the breakdown of hydrogen cyanide to a less toxic compound, formamide. The predicted amino acid sequence of cyanide hydratase in L. maculans is 77% and 82% identical

Molecular phylogeny of the Leptosphaeria maculans-L. biglobosa species complex

Mycological Research, 2003
Leptosphaeria maculans (anamorph Phoma lingam), the ascomycete causing stem canker of crucifers, is a species complex that can be separated into at least seven distinct subgroups using a combination of biochemical and molecular criteria. In the present study sequences of the entire ITS region, including the 5.8S rDNA, of 38 isolates representing the ...

Pentacyclic triterpenes from the fungus, Leptosphaeria maculans

Phytochemistry, 1991
Abstract Fermented broth of the fungus, Leptosphaeria maculans gave two pentacyclic triterpenoid compounds. Based on spectral analysis these compounds were identified as maculaniol and 3α-hydroxy-urs-18,20-dien-28-oic acid.

The teleomorph of the weakly aggressive segregate ofLeptosphaeriamaculans

Canadian Journal of Botany, 2001
Leptosphaeria biglobosa n.sp. is described for the weakly virulent (or non-aggressive) pathogen causing blackleg of oilseed rape and canola. The new species differs from the aggressive blackleg organism, Leptosphaeria maculans (Desm.) Ces. & De Not. in having a very prominent beak on the ascomata that is greatly enlarged at the apex.
