Identification of novel proteins for fungal cell-to-cell communication by localization screening from multicellularity-specific uncharacterized genes Mamun Md. Abdulla Al1, Katayama Takuya1, Cao Wei2, Nakamura Shugo2, Maruyama Junichi1 1 Department of Biotechnology, The University of Tokyo, Bunkyo-ku, Tokyo, Japan 2 INIAD, Toyo University, Bunkyo-ku, Tokyo, Japan Multicellular organisms have the feature of intercellular molecular exchange for cooperation among the cells or tissues. Multicellular fungi possess a primitive morphological structure for cell-to-cell communication, the septal pore. A specifically evolved fungal organelle Woronin body plugs the septal pore upon wounding, thereby protecting the flanking cell. However, comparative genomic approach between multicellular and unicellular fungal species has not yet been employed to investigate additional components/mechanisms in the regulation of cell-to-cell communication. As Ascomycota, one of fungal divisions, possesses a number of genetically characterized species, we performed a genomic comparison between multicellular and unicellular ascomycetes and subsequent localization screening to find novel proteins regulating the cell-to-cell communication via septal pore. In this study, we used Aspergillus oryzae due to having a unique experiment system of quantitatively analyzing the ability to protect the flanking cell upon hypotonic shock- induced hyphal wounding1). Here, 776 genes were selected as multicellularity-specific uncharacterized by using BLAST-based genomic comparison between multicellular ascomycetes (A. oryzae, Aspergillus fumigatus and Aspergillus nidulans) and unicellular ascomycetes (Saccharomyces cerevisiae, Schizosaccharomyces pombe and Candida albicans) along with gene ontology category “no biological data available”. Proteins encoded by the genes were expressed as EGFP fusion in A. oryzae, and 8% of the proteins tested were found to localize to the septum. Approximately 40% of deletion strains lacking the septum-localizing proteins exhibited lower abilities to protect the flanking cell upon wounding. In conclusion, the present genomic comparison along with localization screening allowed us to successfully find many novel proteins having a role in fungal cell-to-cell communication. 1.

Hydrophobins are classified into two classes (class I and class II) according to their amino acid sequence, hydropathy profile, and the solubility of their self-assembled films. Class I hydrophobins adsorb to solid surfaces and are localized at interfaces between hydrophobic and hydrophilic phases, resulting in formation of self- assembled structures so called “rodlets” which are similar to β-amyloid fibrils. Class I hydrophobin RolA produced by Aspergillus oryzae attaches to solid surfaces, recruits polyesterase CutL1, and consequently promotes hydrolysis of polyesters. Because several positively charged residues in the N-terminal region of RolA face to water-phase and are involved in the interaction with CutL1, the orientation of RolA molecule on the solid surface is important. However, the mechanism by which RolA forms the self- assembled structure remains unclear. Using the Langmuir technique, we analyzed the process in which RolA formed the self-assembled structure at the air-water interface. We also transferred the assembled RolA structures onto hydrophobic or hydrophilic silicon basal-plates and observed

    Pectinolytic enzymes of Aspergillus sojae ATCC 20235: The impact of bioprocessing strategy on solid-state production and downstream processing of polygalacturonase by Doreen Heerd A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biochemical Engineering Approved, Thesis Committee Prof. Dr. Marcelo Fernández-Lahore Jacobs University Bremen Prof. Dr. Matthias Ullrich Jacobs University Bremen Dr.-Ing. Dirk Holtmann DECHEMA Research Institute Dr. Sonja Diercks-Horn Jacobs University Bremen Date of Defense: June 14, 2013 School of Engineering and Sciences Summary Since antiquity up to the present Aspergillus spp. like A. oryzae or A. sojae have been used in traditional Japanese fermented food production. The long history of safe use in the production of oriental fermented food favors these microorganisms for their application in industrial enzyme production that are applied in the food industry. This thesis deals with the investigation of A. sojae ATCC 20235 as potential pectinolytic enzyme production organism with focus on polygalacturonase (PG) production under solid-state conditions. Pectinolytic enzymes have been exploited for many industrial applications, e.g. the largest industrial application of these enzymes is in juice and wine production. PGs belong to the pectinolytic enzyme group and are an inherent part of commercial enzyme preparations used for food processing. Recent articles reported about the potential of A. sojae ATCC 20235 to produce PG enzyme in submerged fermentation and via surface cultivation methods. These studies have triggered an interest on the investigation of the potential of this strain for pectinolytic enzyme production in solid-state fermentation (SSF). For this, a microbial screening between A.

Produced by almost all organisms, these carbohydrates are involved in numerous cellular processes, such as cell structuration, protein maturation and signalling, mediation of protein–protein interactions and cell recognition. The ubiquitous presence of mannosides in the environment means they are a reliable source of carbon and energy for bacteria, which have developed complex strategies to harvest them.

  • Transcriptome Analysis of Different Growth Stages of Aspergillus Oryzae
    He et al. BMC Microbiology (2018) 18:12 https://doi.org/10.1186/s12866-018-1158-z RESEARCHARTICLE Open Access Transcriptome analysis of different growth stages of Aspergillus oryzae reveals dynamic changes of distinct classes of genes during growth Bin He, Zhihong Hu, Long Ma, Haoran Li, Mingqiang Ai, Jizhong Han and Bin Zeng* Abstract Background: The gene expression profile and metabolic pathways of Aspergillus oryzae underlying the anatomical and morphological differentiation across different growth stages have not been fully characterized. The rapid development of next-generation sequencing technologies provides advanced knowledge of the genomic organization of A. oryzae. Results: In this study, we characterized the growth and development of A. oryzae at different growth stages, including the adaptive phase, logarithmic phase, and stationary phase. Our results revealed that A. oryzae undergoes physiological and morphological differentiation across the different stages. RNA-seq was employed to analyze the three stages of A. oryzae, which generated more than 27 million high-quality reads per sample. The analysis of differential gene expression showed more genes expressed differentially upon transition from the adaptive phase to the logarithmic and stationary phases, while relatively steady trend was observed during the transition from the logarithmic phase to the stationary phase. GO classification of the differentially expressed genes among different growth stages revealed that most of these genes were enriched for single-organism process, metabolic process, and catalytic activity. These genes were then subjected to a clustering analysis. The results showed that the cluster with the majority of genes with increased expression upon transition from the adaptive phase to the logarithmic phase, and steady expression from the logarithmic phase to the stationary phase was mainly involved in the carbohydrate and amino acid metabolism.

It catalyzes the C-2 oxidation of several aldopyranoses to form the respective 2-keto derivatives, transferring electrons to molecular oxygen to yield hydrogen peroxide. There is indication of an involvement of P2O in lignocellulose degradation; the exact physiological role of P2O, however, is not clearly understood to date. P2O is a potentially interesting enzyme for biotechnological applications, its reaction products (2-keto sugars) can be attractive inter- mediates in the production of food additives, such as fructose, tagatose, or isomaltulose, and can easily be produced in high yields. Trametes multicolor is a potent producer of P2O activity and forms P2O constitutively during growth on a number of carbon sources.
