Trancriptional landscape of Aspergillus niger at breaking of conidial dormancy revealed by RNA-sequencing

ABSTRACT: Genome-wide analysis was performed to assess the transcriptional landscape of germinating A. niger conidia for first hour using next generation RNA-sequencing. The transcriptome of dormant conidia was shown to be highly differentiated from that of germinating conidia. 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. The transcriptome of dormant conidia contained a significant component of antisense transcripts that changed during germination. Dormant conidia contained transcripts of genes involved in fermentation, gluconeogen
