Interdisciplinary approach for the characterization of secondary metabolites pathway gene clusters in the filamentous fungus Podospora anserina.

 

Fungal secondary metabolites are low molecular weight compounds which are not essential for the normal growth of microorganisms but play important roles in development and intercellular communication. Podospora anserina is a typical filamentous ascomycete frequently recovered from dung while sequence analysis of genome reveals its ability to produce secondary metabolites. Deletion of key gene encoding the biosynthetic enzyme of gene cluster and overexpression of pathway- specific transcription factor will be carried out for the characterization of secondary metabolites pathway gene clusters in P. anserina. Isolation of bioactive metabolites (including sterigmatocystin) associated to the understanding of their mode of biosynthesis may offer an opportunity to discover new biocontrol applications.
