Project description:Transcriptomic analysis of LaeA-deletion and overexpression LaeB in LaeA deletion strains in fungus Beauveria bassiana Examination of differential gene expressions by Beauveria bassiana wild type, LaeA-deletion and overexpression LaeB in LaeA deletion strains in fungus Beauveria bassiana
Project description:The ascomycete fungus Beauveria bassiana is a pathogen of hundreds of insect species and is commercially produced as an environmentally friendly mycoinsecticide. Genome-wide insight into the infection of the fungi is critical for genetic improvement of fungal insecticides but has been poorly explored. We constructed three transcriptomes of Beauveria bassiana at 24, 48 and 72 hours post treatment of infection (BbI) and of control (Bbc).
Project description:BbTdp1 is a novel protein with the function of regulating conidium and blastospore yields, fungal morphological changes and pathogenicity in Beauveria bassiana.
Project description:Purpose: This transcriptomic analysis aims at unveiling all possible genes orchestrated by pspA, which is evidently required for insect pathogenicity and virulence-related cellular events of Beauveria bassiana. Methods: Total RNAs were extracted from three 3-day-old hyphal cultures (replicates) of pspA disruption and wild-type strains grown under normal culture conditionsand and subjected to deep sequencing on Illumina NovaseqTM 6000 platform. The sequence reads that passed quality filters were mapped to the genome of Beauveria bassiana. All genes differentially expressed in the disruptant versus the wild-type strain were enriched to GO function classes and KEGG pathways. Results: The resultant transcriptome comprises 10430 genes annotated or not annotated. Among those, 1818 genes (genomic 17.54%) were dysregulated in the absence of pspA, including 806 down-regulated and 1012 up-regulated. Conclusions: pspA lacking any predictable function domain has profound impact on the genomic expression of Beauveria bassiana.
