Gene Expression Systems in Fungi: Advancements and Applications

Biotechnology has emerged as one of the key environmentally safe technologies for the future which enables use of biomass to develop novel smart materials and to replace oil derived products. Fungi are the most efficient producers of the enzymes needed for this purpose and in addition they produce a plethora of secondary metabolites, among which novel antibiotics can be found. Industrial application and exploitation of the metabolic capacities of fungi requires highly productive and robust gene expression systems, which can be achieved by selection of appropriate species and strain improvement. In this book we aim to summarize homologous and heterologous gene expression systems of fungi for production of enzymes and secondary metabolites. A broad overview on requirements, challenges and successful applications shall serve as a basis for further development of fungi as biotechnological workhorses in research and industry.

We bring together articles of experienced and renowned experts and highlight diverse aspects of gene expression systems of fungi We will cover a broad array of topics from industrial requirements to recent advancements and novel solutions The book shall provide a balanced view of advantages for fungal biotechnology and the appropriate systems for the respective applications Includes supplementary material: sn.pub/extras

Dr. Monika Schmoll received her degree and Ph. D. on the topic of Regulation of cellulase expression and signal transduction in the filamentous fungus Hypocrea jecorina ( Trichoderma reesei ) at the Vienna University of Technology, Austria. Besides gaining postdoctoral experience and building her own group at the Vienna University of Technology, she has been a visiting scientist in the laboratory of Professor N. Louise Glass (Department of Plant and Microbial Biology, University of California, Berkeley, USA), the University of Rome La Sapienza and the University of Szeged, Hungary. In 2012, Dr. Schmoll moved to the Austrian Institute of Technology (AIT) in Tulln, Austria, where she is now group leader and senior scientist. In march 2013 she completed her habilitation at the Vienna University of Technology in the field of Molecular Genetics and Genomics.

The primary research field of Dr. Schmoll is the interconnection between light response, sexual development and metabolism, with an emphasis on effects on cellulase gene expression in the filamentous fungus Trichoderma reesei . She showed for the first time that cellulase gene expression is modulated by light in T. reesei and could since then elucidate important mechanistic details on the underlying mechanism. Her group discovered the sexual cycle in the biotechnological workhorse Trichoderma , which had previously been considered asexual. Recently, her group also showed that communication upon sexual development is mediated by regulation of secondary metabolism. Her work with Trichoderma is complemented by contributions to genome annotation of several fungi ( Trichoderma spp., Aspergillus nidulans, Postia placenta, Ceriporiopsis subvermispora, Phlebiopsis gigantea ), especially in the field of signal transduction.
