Project description:Small RNA libraries of 4 different mycovirus-infected and -free isogenic lines of A. fumigatus were constructed using Scriptminer adapters. sRNAomes were analysed and putative virus-derived small RNAs were identified.

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:To investigate the influence of Aspergillus fumigatus on iron regulation in macrophages, we obtained macrophages in culture from human derived monocytes and co-cultured the monocyte-derived macrophages with Aspergillus conidia at a 1:1 ratio. We collected samples at 0, 2, 4, 6 and 8 hours and extracted RNA. We then performed gene expression profiling analysis using data obtained from RNA-seq of control macrophages and macrophage co-cultured with Aspergillus fumigatus at five time points.
Project description:Small RNA libraries of three different mycovirus-infected A. fumigatus isolates were constructed by using Illumina high definition adapters. sRNAomes were analysed and putative virus-derived small RNAs were identified.

Project description:Aspergillus fumigatus is an important human pathogen and a leading fungal killer. This study aimed to determine the small RNA repertoire of A. fumigatus in conidia and mycelium grown for 24 or 48 hours in liquid culture.
Project description:The RNA interference (RNAi) pathway has evolved numerous functionalities in eukaryotes, with many on display in Kingdom Fungi. RNAi can regulate gene expression, facilitate drug resistance, or even be altogether lost to improve virulence potential in some fungal pathogens. In the WHO fungal priority pathogen, Aspergillus fumigatus, the RNAi system is known to be intact and functional. To extend our limited understanding of A. fumigatus RNAi, we performed a multi-condition mRNA-seq analysis comparing expression of several RNAi double knockout mutants with the wild-type strain in conidia and mycelium grown for 24 or 48 hours. The analysis linked the A. fumigatus dicer-like enzymes and RNA-dependent RNA polymerases to regulation of conidial ribosome biogenesis. Cumulatively, A. fumigatus RNAi appears to play an active role in defense against double-stranded RNA species alongside a previously unappreciated housekeeping function in regulation of conidial ribosomal biogenesis genes.

Project description:To better understand the effect of hypoxia, RNA-Seq technology was used to profile the Aspergillus fumigatus during adaptation to hypoxia at 12, 24 and 36 h time points.
