Project description:The transcription factor CrzA influences cell wall organization in the pathogenic fungus Aspergillus fumigatus, and also binds to the promoter regions of chitin synthase genes upon exposure to the antifungal drug caspofungin. To gain an overview of the genes directly regulated by CrzA, the CrzA binding sites were determined genome-wide by ChIP-seq
Project description:Genomic DNA from five strains, Aspergillus fumigatus Af71, Aspergillus fumigatus Af294, Aspergillus clavatus, Neosartorya fenneliae, and Neosartorya fischeri, were co-hybridized with that of Aspergillus fumigatus Af293 and compared.
Project description:Aspergillus bombycis was first isolated from silkworm frass in Japan. It has been reportedly misidentified as A. nomius due to their macro-morphological and chemotype similarities. We sequenced the genome of the A. bombycis Type strain and found it to be comparable in size (37 Mb), as well as in numbers of predicted genes (12,266), to other sequenced Aspergilli. The aflatoxin gene cluster in this strain is similar in size and the genes are oriented the same as other B- + G-aflatoxin producing species, and this strain contains a complete but nonfunctional gene cluster for the production of cyclopiazonic acid. Our findings also showed that the A. bombycis Type strain contains a single MAT1-2 gene indicating that this species is likely heterothallic (self-infertile). This draft genome will contribute to our understanding of the genes and pathways necessary for aflatoxin synthesis as well as the evolutionary relationships of aflatoxigenic fungi.
