This is a book about experiments and results of experiments. The results described are the fruit of thirty years' labour in the field of secondary metabolism. Secondary metabolism, more than any other part of the chemistry of life, has been the special preserve of organic chemists. Investiga tion of secondary metabolism began with curiosity about the struc tures of compounds isolated from natural sources, i.e. secondary metabolites. Coeval with structure determination there has been a curiosity about the origins and mechanism of formation of secondary metabolites (or natural products as they have been called). It is the experimental outcome of this curiosity that is described here. This account is primarily intended to be an introduction to the biosynthesis of secondary metabolites. I have also endeavoured, however, to make the book as comprehensive as possIble. This has meant that some of the material has had to be presented in abbrevi ated form. The abbreviated material is largely confined to particular sections of the book. The paragraphs marked with a dagger (t) can be omitted by the reader wishing to acquire a general introduction to the subject. A blend of the most significant and the most recent references is cited to provide the reader with ready access to the primary litera ture. This is clearly most necessary for the material presented in abbreviated form. Relevant reviews are also cited.

Fungal natural products are friends and foes of humans such as deleterious mycotoxins, cytotoxic, carcinogenic compounds or beneficial compounds such as antibiotics, fungicides, insecticides, antiviral and antitumor metabolites. Understanding fungal diversity and estimation of fungal species on our planet poses a great challenge to researchers. This complexity is further multiplied by secondary metabolite diversity of fungi, which requires interdisciplinary studies. It is extremely important to understand the fungal secondary metabolism to stop human, animal and plant diseases caused by fungi and harvest their valuable metabolites. Furthermore, many secondary metabolite gene clusters are silenced under laboratory conditions. It is vital to develop effective methods to activate those clusters in order to discover novel potent metabolites. This e-book is a compilation of original review articles contributed by leading fungal secondary metabolite researchers with a wide range of expertise. Important aspects of fungal secondary metabolism, including regulation, genome mining, evolution, synthetic biology and novel methods have been discussed. This book will be a great source to those people, who are interested in understanding overall structure, diversity and regulation of production of these tiny but precious chemicals.

Plant secondary metabolism is an economically important source of fine chemicals, such as drugs, insecticides, dyes, flavours, and fragrances. Moreover, important traits of plants such as taste, flavour, smell, colour, or resistance against pests and diseases are also related to secondary metabolites. The genetic modification of plants is feasible nowadays. What does the possibility of engineering plant secondary metabolite pathways mean? In this book, firstly a general introduction is given on plant secondary metabolism, followed by an overview of the possible approaches that could be used to alter secondary metabolite pathways. In a series of chapters from various authorities in the field, an overview is given of the state of the art for important groups of secondary metabolites. No books have been published on this topic so far. This book will thus be a unique source of information for all those involved with plants as chemical factories of fine chemicals and those involved with the quality of food and ornamental plants. It will be useful in teaching graduate courses in the field of metabolic engineering in plants.

Research on microbes plays an essential role in the improvement of biotechnological and biomedical areas. It has turned into a subject of expanding significance as new organisms and their related biomolecules are being characterized for several applications in health and agriculture. Microbial biomolecules confer the ability of microbes to cope with a range of adverse conditions. However, these biomolecules have several advantages over the plant origin, which makes them a suitable target in drug discovery and development. The reasons could be that microbial sources can be genetically engineered to enhance the production of desired natural production by large-scale fermentation. The interaction between microbes and their biotic and abiotic environment is fundamental to numerous processes taking place in the biosphere. The natural environments and hosts of these microorganisms are extremely diverse being reflected by the fact that microbes are widespread and occur in nearly every biological community on Earth. This metabolic versatility makes microbes interesting objects for a range of economically important biotechnological applications. Most of the biotechniques are established but inefficient genetic engineering strategies are still a bottleneck for selected microbe producing industrial scale biomolecules. Therefore, untapped microbial biodiversity and related metablomics, give a noteworthy wellspring of biologicals for the advancement of meds, immunizations, enhanced plants and for other natural applications. The present eBook volume contains articles on microbial secondary metabolites, microbial biosynthetic potential including biosynthetic gene expression, and metagenomics obtained from microorganism isolated unique from habitats like marine sources, endophytes, thermal springs, deserts, etc.

Since 1984 and 1988, when meetings were held on the topic of primary and secondary metabolism of plant cell cultures, there has been a clear shift of the focus of ongoing research. While the cell culture itself and the production of secondary metabolites and the biosynthetic pathways and the activity of enzymes were major topics, now these aspects are linked with genes, i.e. molecular biology becomes more prominent. This state-of-the-art book has contributions on such subjects as fermentation, enzymology of secondary metabolism, catabolism of secondary metabolites, elicitation of pathways and genetic modification of metabolic pathways. It includes contributions on the most recent achievements in the research on among other things tropane and indole alkaloids, phenolics, (iso)flavonoids, terpenes and cardenolides. It is an excellent review of the progress made in the past years and a perspective on the future developments.

​Fungi produce many chemically diverse secondary metabolites whose biological roles largely remain elusive. Within the increasing number of sequenced fungal genomes several important genes involved in secondary metabolite formation have been identified. Most of these genes are clustered and their coordinated transcription is controlled in a complex way by both narrow pathway-specific regulators as well as broad global transcription factors responsive to environmental cues. In recent years it was discovered many of the newly identified gene clusters are silent under laboratory conditions suggesting that the biosynthetic potential of fungi is far from being exploited. Besides identifying novel bioactive metabolites from still unexplored sources, the activation of these gene clusters by several approaches may result in the discovery of new substances with antibiotic and pharmaceutical benefits. This book covers recent advances in the field of fungal secondary metabolisms ranging from methodologies to biological aspects and will include the latest knowledge on fungal molecular biology, genomics, and metabolomics. With the related volume by Professor Juan-Francisco Martin, where the most relevant and well-studied fungal secondary metabolites are compiled, this book provides a comprehensive overview of the state-of-the-art of research on fungal secondary metabolites.
