Project description:In order to obtain genetically engineering strain of Penicillium oxalicum with high Raw Starch Digesting Glucoamylase production,we deleted PoxCxrC and overexpressed POX_f08097 in Penicillium oxalicum TE4-10 ,and we want to investigating the function of deletion of PoxCxrC and overexpression of POX_f08097 at transcriptional level.
Project description:RNA-seq was used to compare differential gene expressions for Penicillium oxalicum wild type strain (M12) and sporognesis related genes knock out strains.The goals of this study are to construct the sporogenesis regulation pathway of Penicillium oxalicum. Examination of differential gene expressions by digital gene expression tag profiling in Penicillium oxalicum wild type strain and nine mutant strains (flbA knoutout strain, flbB knoutout strain, flbC knoutout strain, flbD knoutout strain, flbE knoutout strain,wetA knoutout strain, abaA knoutout strain,stuA knoutout strain, swi6 knoutout 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.

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), Hat1 deletion strain (ΔHat1) and AmyR deletion strain (ΔAmyR) 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 ΔHat1 strain were significantly different, and the gene expression levels between ΔAmyR and the wild strain were also significantly different. The deletion of Hat1 significantly up-regulates the expression levels of amylase genes of Penicillium oxalicum, and the absence of AmyR can significantly down-regulate the expression level of amylase genes genes, indicating that Hat1 and AmyR can cause a difference in amylase synthesis by affecting the expression of amylase genes. The information provided by this study indicates that Hat1 and AmyR functions are necessary for the amylase activity of Penicillium oxalicum.
