Oilseed rape plant infected with Leptosphaeria maculans

Leptosphaeria maculans 'brassicae' is a fungal pathogen belonging to the Dothideomycetes. It infects the important biofuel crop oilseed rape (Braccica napus) and causes 'stem canker' or 'blackleg'. Average yield losses of 5-20% have been reported.

L. maculans has a complex life cycle, which includes alternating phases of saprophytism on stem residues, a short phase of necrotrophy on leaves, a long phase of (stealth) endophytism within plant tissues and eventually necrotrophy at the basis of the stem, killing the plant.

The genome of L. maculans has been sequenced by Genoscope EVRY and annotated by URGI-INRA (Rouxel et al, 2011). In order to allow comparative analyses with other Dothideomycete genomes sequenced by the Joint Genome Institute and other sequencing centers, a copy of this genome is incorporated into Mycocosm.
