(described by Cesati and de Notaris in ) Taxonomic Classification Kingdom: Fungi Phylum: Ascomycota Class: Euascomycetes Order: Pleosporales Family: Leptosphaeriaceae Genus: Leptosphaeria Description and Natural Habitats Leptosphaeria is a dematiaceous (phaeoid, or dark-walled) filamentous fungus found in the soil. It grows in its teleomorphic phase. One of its . Leptosphaeria bicolor, causal agent of a leaf scorch disease of sugar cane, is referred to the new genus Saccharicola. The ascospores are transseptate and hyaline at . Due to this rudimentary circumscription many, often remotely related, taxa have been placed in this genus. In recent years, more thorough reexamination and taxonomic reassessment of many species of Leptosphaeria have resulted in their disposition in other allied genera. Philippe Tixier, Régis Sabbadin, in Advances in Ecological Research, The system and targeted services. Long-term management of phoma stem canker on oilseed rape, caused by the species complex Leptosphaeria maculans /L. biglobosa, was chosen as a case study because of the economic importance of the disease and the substantial scientific knowledge available .
The genus Phoma is typified by Phoma herbarum (Boerema ).This species has thus far not been linked to any teleomorph, but several other species that are currently accommodated in Phoma do have a sexual state. The species in the section Pilosa are linked to the teleomorph genus Pleospora, while many species in the section Plenodomus have a sexual state in Cited by: On the basis of PCR analysis, all isolates originating from Serbia belong to L. complex: belong to species Leptosphaeria maculans, and 8 to species Leptosphaeria biglobosa NA1 ('Leptosphaeria. Introduction. Blackleg disease, caused by the hemibiotrophic fungal pathogen Leptosphaeria maculans (Desm.) Ces. et de Not. is a major threat to the consistent global supply of canola (Brassica napus L).Canola is sown as a spring crop in the North Americas, winter crop in Europe and autumn crop in Australasia, and contributes approximately 14% of world Cited by: Polymorphism of Tox Leptosphaeria maculans isolates as revealed by soluble protein and isozyme electrophoresis.

The anamorphic genus Phoma was subdivided into nine sections based on morphological characters, and included teleomorphs in Didymella, Leptosphaeria, Pleospora and Mycosphaerella, suggesting the polyphyly of the genus. Recent molecular, phylogenetic studies led to the conclusion that Phoma should be restricted to present study Cited by: Phaeosphaeria herpotrichoides (De Not.) L.

The distribution of the highly virulent and weakly virulent types ofLeptosphaeria maculans, causal agent of blackleg of oilseed rape, was studied in two fields in southern a polymerase chain reaction-based assay with primers specific for these virulence types, plant tissues were directly examined for the occurrence of the by:
