(larch needles) Host (poplar) 20-21 August 2008, Nancy Mating types genes in Melampsora

3 Mating process Mating pheromone response pathway meiosis hyphal growth
a hyphal growth nuclear fusion cell fusion 20-21 August 2008, Nancy Mating types genes in Melampsora

4 Mating pheromone response pathway
cdc25 Ste6 Gpa1 β γ GDP Receptor GTP Pheromone HMG P Ras1 MAPKKK MAPKK MAPK ACTIVATION cdc24 Cdc42 Ste20 MORPHOLOGY Nucleus Cytoplasm Plasma Membrane pheromone receptor mating type transcription factor genes Mating Response Genes Conserved between ascomycetes and basidiomycetes 20-21 August 2008, Nancy Mating types genes in Melampsora

5 Tetrapolar system Two unlinked loci determined the mating type in 60% of Basidiomycetes A locus: HD1 HD2 a pair of divergently transcribed homeodomain transcription factor STE3 Ph B locus : - lipopeptide pheromones - G-protein-coupled pheromone receptor 20-21 August 2008, Nancy Mating types genes in Melampsora

11 Conclusions and Perspectives
Melampsora larici-populina genome present the A and B mating type genes No synteny is observed between the regions surrounding the A and B loci of Melampsora larici-populina and Puccinia graminis Experimental investigations are needed to confirm the tetrapolar mating-type system of Melampsora larici-populina and to identify “the B locus”. 20-21 August 2008, Nancy Mating types genes in Melampsora
