Aspergillus fumigatus causes a wide range of diseases that include mycotoxicosis, allergic reactions and systematic diseases (invasive aspergillosis) with high mortality rates. In recent years, considerable progress in the genome sequencing of this fungus has been made by an international consortium, which includes the Wellcome Trust Sanger Institute (UK) and the Institute for Genome Research (USA). A tenfold whole genome shotgun sequence assembly of A. fumigatus has been made publicly available. In this study, it was attempted to identify the genes related to the phospholipid biosynthesis from the A. fumigatus genome by a gene prediction program (GlimmerM) and to reconstruct the metabolic pathway for phospholipids of A. fumigatus . Fifteen genes related to phospholipid pathway were identified in the A. fumigatus genomic sequence. The open reading frames predicted by GlimmerM showed a high amino acid sequence similarity with the other fungal phospholipid biosynthetic genes and well‐conserved functional domains. The obtained results also demonstrated that the reconstructed pathway of A. fumigatus in phospholipid biosynthesis was very similar to that of other fungi such as Saccharomyces cerevisiae , Schizosaccharomyces pombe , Candida albicans , and Neurospora crassa . Therefore it is postulated that the antifungal drugs targeted for the biosynthesis of phospholipids could also be effective against A. fumigatus .
