Title: pah1<i>: a homeobox gene involved in hyphal morphology and microconidiogenesis in the filamentous ascomycete</i>Podospora anserina
Abstract: Homeobox‐containing genes are widely described among eukaryotic species other than filamentous ascomycetes. We describe here the isolation and characterization of the first homeobox gene ( pah1 ) identified in a filamentous ascomycete. It encodes a putative protein of 610 amino acids containing a typical homeodomain with 60 amino acids. Deletion of the pah1 gene enhances the number of male gametes (microconidia), whereas overexpression of pah1 results in a decrease in microconidia. These results led us to suppose that pah1 may be a repressor of genes involved in the microconidiation process. Moreover, pah1 is involved in hyphal branching and possibly in the development of female organs.
