Transcriptomic analysis of fungus Penicillium oxalicum and its laeA, clrB and rcoA deletion strains

ABSTRACT: The goals of this study are to compare differential gene expressions for Penicillium oxalicum wild type strain (WT), laeA knockout strain (ΔlaeA), rcoA knockout strain (ΔrcoA), and clrB knockout strain (ΔclrB). The deletion of laeA downregulated genes involved in oxidation- reduction process, alkaloid metabolic process, and transmembrane transport. We find the expression levels of seven secondary metabolism gene clusters (totally 28 clusters) were silenced inΔlaeA. The deletion of clrB downregulated genes involved in hydrolase activity, acting on glycosyl bonds. Many genes involved in conidiation were drastically regulated in ΔrcoA. This study provides the information that combined laeA, clrB and rcoA function are required in conidiation and hydrolase activity of P. oxalicum.

Transcriptomic analysis of fungus Penicillium oxalicum and its set2 deletion strains

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), and set2 knockout strain (Δset2) in different carbon sources. The deletion of set2 upregulated genes involved in oxidation- reduction process, extracellular region, and plasma membrane ATP synthesis coupled proton transport both with 2% glucose or 1% cellulose and 1% wheat bran as carbon sources. We find the expression levels of 20 secondary metabolism gene clusters were upregulated or downregulated under different carbon sources in Δset2. This study provides the information that SET2 function are required in conidiation and hydrolase activity of P. oxalicum.

Cap analysis gene expression (CAGE) of Aspergillus luchuensis mut. kawachii control and laeA disruptant strains

Project description:LaeA, a putative methyltransferase, is a global regulator for metabolic and development process in filamentous fungi. We characterized the laeA homologous genes in the white koji fungus, Aspergillus luchuensis mut. kawachii (A. kawachii) to examine their role in citric acid production. The ΔlaeA strain showed a significant reduction in the citric acid productivity. The cap-analysis gene expression (CAGE) revealed the laeA is required for the gene expression of a putative citrate exporter encoding cexA, which has a critical role for the citric acid production. The deficient citric acid productivity of the ΔlaeA strain was remedied by overexpression of cexA to a comparative level to that of the cexA overexpressing ΔcexA strain. In addition, chromatin immunoprecipitation coupled with quantitative PCR (ChIP-qPCR) analysis indicated that LaeA regulates gene expression of the citrate exporter encoding cexA gene via histone H3K4 and histone H3K9 methylation levels. These results indicate that LaeA is involved in the citric acid production through epigenetic regulation of cexA in A. kawachii.

Transcriptomic analysis of fungus Penicillium oxalicum and its mtr23B deletion and complemented strains

Project description:The goals of this study are to compare differential gene expressions for Penicillium oxalicum wild type strain (WT), mtr23B knockout strain (Δmtr23B) and complemented strain (Rmtr23B) on Vogel’s medium with 2% glucose (G) or 1% wheat bran and 1% cellulose (CW) as carbon resources. When cultivated in a repression medium for cellulolytic enzyme formation (G), the deletion of mtr23B upregulated genes involved in lyase activity, hydrolase activity, acyl carrier activity, monooxygenase activity, electron transfer activity, phosphopantetheine binding, heme binding, cell wall organization or biogenesis, oxidation-reduction process and extracellular region. The downregulated genes in Δmtr23B were mainly involved in transmembrane transporter activity, amino acid transmembrane transporter activity, membrane and integral component of membrane. When cultivated in an inducing medium for cellulolytic enzyme formation (CW), the downregulated genes in Δmtr23B were mainly involved in glucosidase activity, polygalacturonase activity, oxidoreductase activity, heme binding, oxidareductase activity, xylanase activity, cellulase activity, cellulose binding, oxidation-reduction process, cellulose catabolic process, xylan catabolic process and extracellular region. We find the expression levels of five secondary metabolism gene clusters (totally 28 clusters) were silenced in Δmtr23B. This study provides the information that mtr23B is required in conidiation and hydrolase activity of P. oxalicum.

LaeA regulates mycelium growth by mediating H3K9 methylation in Myceliophthora thermophila [WGBS]

Project description:The low efficiency of fungal growth and substrate utilization is a barrier to high yield and productivity of target products during fungal fermentation. However, elaborated and intricate regulatory mechanisms of fungal growth remains inconclusive. In this study, we found deletion of putative methyltransferase LaeA enhanced sugar consumption and fungal growth rate of M. thermophila. The exploration of the mechanism of LaeA regulation revealed that transcription factor (Cre-1, Grf-1, Grf-2 and Grf-3) acted as negative repressor of intracellular metabolism, of which expression was indirectly regulated by LaeA. Moreover, higher gluconeogenesis activity is crucial for elevated fugal growth rate and PCK might be the core notes of metabolism network relative to fungal vegetative growth. Further in vivo global histone methylation assay and in vitro biochemical analysis declared LaeA was a methyltransferase with histone H3 lysine 9 (H3K9) as the substrate and regulated growth properties by directly modulating H3K9 methylation levels. ChIP-seq analysis displayed significantly reduced H3K9me3 in region of pck locus in strain ΔlaeA, implying methylation modification of pck might be the way of LaeA regulating growth phenotypes. Additionally, whole-genome bisulfite sequencing (WGBS) analysis demonstrated methylation of cytosines (5mC) in genomic DNA was carried out and correlated to the methylation of H3K9 modified by LaeA. Taken together, our research declared LaeA possessed methyltransferase activity, targeting H3K9 and participated in regulation of fugal properties, including on sugar consumption, mycelium growth, cellulase production, secondary metabolism, and oxidative stress tolerance, providing new insights into the epigenetics of filamentous fungi.
