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:Fungal entomopathogens like Beauveria bassiana (Bals.) Vuill. (Ascomycota: Hypocreales) are known as antagonist of insects with multiple functional and ecological roles and have attracted increased attention as biocontrol agents in integrated pest management programs. A microarray analysis was performed to work out fundamental aspects of genes involved in the interaction between grapevine and the endophytic fungus B. bassiana. The results indicate an up-regulation of diverse defense-related genes in grapevine as a response to a treatment with B. bassiana
Project description:Methods: Total RNAs were extracted from three 3-day-old hyphal cultures (replicates) of dim5 disruption and wild-type strains grown under normal culture conditions and and subjected to deep sequencing on Illumina Novaseq 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 10915 genes annotated or not annotated. Among those, 1201 genes (genomic 11.59%) were dysregulated in the absence of dim5, including 489 down-regulated and 712 up-regulated. Conclusions: DIM5 has profound impact on the genomic expression of 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:Purpose: This transcriptomic analysis aims at unveiling all possible genes orchestrated by Cre1, 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 cre1 deletion 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 deletion mutant versus the wild-type strain were enriched to GO function classes and KEGG pathways. Results: The resultant transcriptome comprises 10364 genes annotated or not annotated. Among those, 1881 genes (genomic 18.149%) were dysregulated in the absence of cre1, including 1117 down-regulated and 764 up-regulated. Conclusions: Cre1 has profound impact on the genomic expression of Beauveria bassiana.
