Comparative genomic, transcriptomic and secretomic profilings of Penicillium oxalicum HP7-1 and its cellulase and xylanase hyper-producing mutant EU2106, and identification of two novel regulators for cellulase and xylanase gene expression

Project description:In this study,comparative genomic, transcriptomic and secretomic profilings of Penicillium oxalicum HP7-1 and its cellulase and xylanase hyper-producing mutant EU2106 were employed to screen for novel regulators for cellulase and xylanase gene expression.

Large scale transcriptome analysis was used to identify the genes most related to the transcription of cellulase genes and/or xylanase genes expression

Project description:Based on the transcriptome data of deletion mutants of different genes and different culture conditions of Penicillium oxalicum, the correlation of gene transcription levels in the whole genome was calculated to explore the genes most related to the transcription of cellulase gene and/or xylanase gene in Penicillium oxalicum, including transcription factors, sugar transporters and other functional genes.

Transcription factor CrzA modulate fungal development and cellulolytic gene expression in Penicillium oxalicum

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), CrzA deletion strain (ΔCrzA) and CrzA recover strain (ReCrzA) in 2% starch as carbon sources. The correlation analysis results between the various samples showed that the gene expression levels of the wild strain and the RecrzA strain were similar, and the gene expression levels between ΔcrzA and the wild strain were significantly different. The deletion of CrzA significantly down-regulates the expression levels of conidia pigment synthesis genes, and spore wall synthesis-related genes of Penicillium oxalicum, and also has a regulatory effect on the expression levels of genes related to the sporulation process. And the absence of CrzA can broadly down-regulate the expression level of cellulase-encoding genes, indicating that CrzA can cause a decrease in cellulase synthesis by affecting the expression of cellulase-encoding genes. The information provided by this study indicates that CrzA function is necessary for the mycelial development and cellulase activity of Penicillium oxalicum.

The effects of ClrB internal mutant overexpression and creA deletion on the transcriptome of Penicillium oxalicum

Project description:The synthesis of cellulolytic enzymes by filamentous fungi are mainly regulated at the transcriptional level. The essential role of transcriptional activator ClrB/CLR-2 in the induction of cellulase genes has been reported in several fungal species. In this study, we identified the C-terminal region of ClrB in Penicillium oxalicum as a transcriptional activation domain using a yeast reporter gene system. Overexpression of a mutant ClrBID fusing the DNA-binding and transcriptional activation domains of ClrB together enabled cellulase production under cellulase non-inducing conditions. Strikingly, the ClrBID-overexpression strain produced cellulase in the presence of glucose at a level similar to that of reference strain on cellulose. Combination of ClrBID overexpression and deletion of carbon catabolite-repressor gene creA suggested an additive effect of the two manipulations on carbon catabolite de-repression. A similar modification of ClrB in Aspergillus niger also resulted in cellulase production on glucose. The results indicated that the post-transcriptional control of ClrB activity involves its central region, and provided a potential strategy for engineering Penicillium and Aspergillus strains for cellulase production on easy-to-use carbon sources.

FaiR regulates the development of Penicillium oxalicum fungi and the expression of cellulolytic genes

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT) and FaiR deletion strain (DfaiR) under conditions of 1% bran + 1% microcrystalline cellulose as carbon source. The results of correlation analysis between each sample showed that the gene expression level of DfaiR was significantly different from that of the WT strain. The deletion of DfaiR significantly down-regulates the expression levels of sporulation process genes. And the absence of DfaiR can broadly up-regulate the expression level of cellulase-encoding genes, indicating that DfaiR can cause a decrease in cellulase synthesis by affecting the expression of cellulase-encoding genes.

The F-box protein Fbx23 regulates the development of Penicillium oxalicum fungi and the expression of cellulolytic genes

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), Fbx23 deletion strain (Δfbx23), and Fbx23 ecover strain (Refbx23) under conditions of 2% glucose or 1% bran + 1% microcrystalline cellulose as carbon source. The results of correlation analysis between each sample showed that the gene expression level of Δfbx23 was significantly different from that of the WT strain. The deletion of Fbx23 significantly down-regulates the expression levels of sporulation process genes. And the absence of Fbx23 can broadly up-regulate the expression level of cellulase-encoding genes, indicating that Fbx23 can cause a decrease in cellulase synthesis by affecting the expression of cellulase-encoding genes.

Expression profiling analysis of fungus Penicillium oxalicum wild type strain and its Podot1 deletion strain.

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), and Podot1 knockout strain (ΔPodot1) in different carbon sources. The deletion of Podot1 downregulated genes involved in the septin complex, extracellular region, and interspecies interaction between organisms when strains were cultivated with 2% glucose as carbon sources, and downregulated genes involved in cellulase activity, cellulose binding, glucosidase activity, and polysaccharide catabolic process when strains were cultivated with 1% microcrystalline cellulose and 1% wheat bran as carbon sources. We find the extracellular region was downregulated under both different carbon sources in ΔPodot1. This study provides the information that PoDot1 function are required in mycelial development and hydrolase activity of P. oxalicum.
