Project description:Conidia germination is critical for fungi to colonize various habitats. We sampled RNA expression at four stages of conidia germination, including fresh conidia (15min), polar growth (120min), doubling of long axis (240min), and first hyphal branching (360min) in Neurospora crassa. Cultures were made on Bird medium, and two biological replicates were collected for all data points. The growth was under a labratory condition of 375C and constant light.

We sampled RNA expression at four stages of conidia germination, including fresh conidia (15min), polar growth (120min), doubling of long axis (240min), and first hyphal branching (360min) in Neurospora crassa. Cultures were made on two different media, including Bird medium supporting only asexual development and maple sap medium supporting both asexual and sexual development, and two biological replicates were collected for all data points. The growth was under a labratory condition of 25C and constant light.

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.

Project description:Genome-wide analysis was performed to assess the transcriptional landscape of germinating A. niger conidia using GeneChips. The metabolism of storage compounds during conidial germination was also examined and compared to the transcript levels from associated genes. The transcriptome of dormant conidia was shown to be highly differentiated from that of germinating conidia and major changes in response to environmental shift occurred within the first hour of germination. The breaking of dormancy was associated with increased transcript levels of genes involved in the biosynthesis of proteins, RNA turnover and respiratory metabolism. Increased transcript levels of genes involved in metabolism of nitrate and proline at the onset of germination implies their use as sources of nitrogen. Dormant conidia contained transcripts of genes involved in fermentation, gluconeogenesis and the glyoxylate cycle. The presence of such transcripts in dormant conidia may indicate the generation of energy from non-carbohydrate substrates during starvation-induced conidiation or for maintenance purposes during dormancy. The immediate onset of metabolism of internal storage compounds after the onset of germination, and the presence of transcripts of relevant genes, suggest that conidia are primed for the onset of germination.

Project description:Two long serial analysis of gene expression (LongSAGE) libraries of germinating conidia of Botrytis cinerea were generated with and without resveratrol treatments for unraveling the antifungal mechanisms of this phytoalexin by global transcriptome analysis – 82,786 total tags and a minimum of 15,665 unitags were obtained respectively. By tag-to-gene mapping, about 55% of the total unitags were matched to known genes. There were 109 unitags that showed significant differences in the two LongSAGE libraries, corresponding to 43 up- and 44 down-regulated genes, and 22 unmatched unitags as new gene candidates. These results showed that resveratrol inhibited expression of genes related to the glycolysis-Krebs cycle and mitochondrial electron transport chains at multiple sites in conidia germination, with induction of modified Entner–Doudoroff pathway as metabolic compensation. The chaperone-mediated protein folding and ubiquitin proteolysis systems were inhibited, while detoxification of resveratrol via ABC transporters was activated in this fungal pathogen.
