Project description:Expression data from batch cultivations of Aspergillus niger wild type strain ATCC 1015 and adrA, facB and creA deletion mutants constructed on ATCC 1015 background strain with glucose or glycerol as carbon sources. Genome-wide transcriptome analysis was used to identify genes either affected directly or indirectly by each transcription factor investigated during growth on a repressing or a derepressing carbon source. For this purpose, batch cultivations under well-controlled conditions were performed with Aspergillus niger wild type strain ATCC 1015 and the three deletion mutants of the corresponding transcription factors AdrA, FacB and CreA. Samples for RNA extraction were collected and further processed for hybridization in custom-designed Affymetrix microarrays containing probes for three Aspergillus species, including A. niger.

Samples for RNA extraction were collected and further processed for hybridization in custom-designed Affymetrix microarrays containing probes for three Aspergillus species, including A. niger. Triplicate batch fermentations of each of the four Aspergillus niger strains used, the wild type A. niger strain ATCC 1015 and three gene deletion mutants, were carried out using glucose or glycerol as carbon source, and transcriptome analysis was performed. Biomass from each batch cultivation was harvested in the exponential phase of growth and further processed for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Comparative genomics and transcriptomics of the filamentous fungi Aspergillus oryzae and Aspergillus niger have opened possibilities for investigating the cellular metabolism and regulation of these fungi on a systemic level. The aim of this work was to understand how metabolism is regulated and to identify common regulatory responses between A. oryzae and A. niger. We therefore conducted batch fermentations with A. oryzae and A. niger grown on three different carbon sources (glucose, maltose, and xylose) in order to investigate their genome-wide transcription response Keywords: Two Aspergillus species and different carbon sources

Project description:Microarray analysis was used to compare gene expression of Aspergillus fumigatus under two different sporulation temperatures, 17oC and 32oC, with an emphasis on genes encoding known or putative allergens of the fungus. The objective of the study was to investigate whether allergenic potencies of A. fumigatus spores produced under different sporulation temperatures would be influenced by temperature-dependent transcriptional regulation of allergenicity genes.

Project description:Aspergillus niger produces a variety of lignocellulolytic enzymes (cellulases, hemicellulases, among others) and is regarded as cell factory for the production of heterologous proteins. Therefore, there is a growing interest in the study of its genes and the understanding of the cellular mechanisms in order to expand its applications. On the other hand, we have shown that enzyme production by A. niger is higher when grown forming biofilms than when grown conventionally in submerged systems. The objective of this study was to perform a global transcriptomic analysis and an expression analysis of both lignocellulases and biofilm regulatory genes as compared to A. niger in submerged culture. DNA microarray assays were performed to investigate the global gene expression which yielded information on the expression of more than 90% of A. niger genes. To further this comparison, the two culture systems were supplemented with different carbon sources (glucose, lactose, xylose and maltose) to establish a differential gene expression under different culture conditions. Also, to validate the differential expression qPCR was performed for quantitative comparison of the transcriptional level of genes in both culture systems.

Project description:Conidia of Aspergillus niger are characterized by a dormant state and are moderate stress-resistant. Upon contact with a moist substrate, germination of conidia occurs by changing from a dormant stabilized state towards a growing vegetative cell. The RNA expression levels of dormant conidia and conidia that were in various stages of germination were studied. The RNA composition of dormant conidia was substantially different than all the subsequent stages of germination. This indicates that the distinct morphological changes that occur during germination are not correlated with the highest change in the transcriptome. Samples of germinating conidia of Aspergillus niger N402 were taken in triple at 0h (dormant), 2h, 4h, 6h and 8h after inoculation in CM.
