Book Description
PTRMS-TOF analysis of Armillaria volatomic proufb01le was used as molecolar tools for the taxonomic identification of six European species of genus Armillaria: A. borealis , A. cepistipes, A. gallica, A. mellea, A. ostoyae and A. tabescens. This mycete is known as honey mushroom and it is one of the main opportunistic pathogenic fungus found in many forest and ornamental trees where it causes white root rot. It is also a saprotroph who allows the wood degradation and the easy transfer, by wood trade, the other more than 40 esotic species present in the other continents. Volatile Organic Compounds (VOC) pattern was analyzed for 77 strains of Armillaria by PTR- MS-TOF technique in order to discriminate the species. Armillaria strain were previously identified by DNA ampliufb01cation by PCR. Samples were analyzed after 30 days of incubation to allow the mycelial growth on MEA substrate added with silver ufb01r sawdust. Data analysis was performed using univariate and multivariate statistical tools. The analysis of variance (ANOVA) discriminated A. borealis by using acetylene concentration and A. cepistipes by using hexanal concentration. The distribution of specific masses concentration, as a function of species by boxplots, allows to discriminate A. tabescens, A. borealis, A. cepistipes and A. mellea. Principal component analysis allows discriminate the A. borealis and A. tabescens clusters. The future improvement of this approach is to identify some VOC which can discriminate invasive Armillaria species to develop a rapid and accurate identification diagnostic method based on gas chromatographic separation of these VOCs.

Book Description
The fungus Heterobasidion annosumis, in economic terms, the most important causal agent of disease and of yield loss in coniferous trees in northern temperate regions. This is the first book which brings together and summarizes the considerable amount of knowledge which has been gathered about all aspects of this disease. It has been prepared and published with support from the European Union, under the Agriculture and Agro- Industrial Research (AAIR) program. Drawing on over 2,000 research papers and books published from the early nineteenth century to the present day, the book covers topics which include the history, detection, biology, taxonomy and distribution of H. annosum. It provides the latest information on infection, host resistance, the biochemistry of the host-parasite interaction, molecular and genetic regulation of the host response and methods of control. It concludes with a series of case studies from Europe and North America. This book is an indispensable source of information for all those involved in the management of coniferous forests and plantations wishing to reduce the impact of this disease on yields. It should also become the accepted text for students of forestry and plant pathology studying H. annosum, and an invaluable reference manual for scientists researching this and other fungal tree diseases.

Book Description
The Plant Root and the Rhizosphere was a major topical feature of the first International Symposium on Factors Determining the Behavior of Plant Pathogens in Soil held at the University of California, Berkeley in 1963. The symposium was edited by K. F. Baker and W. C. Snyder and published under the title Ecology of Soil-Borne Plant Pathogens. Since that time, several other international efforts, either on the root-soil interface specifically or on topics relating to the root environment, have provided"a wealth of valuable information basic to promoting the culture of healthier, more productive plants. For the writing of this book, inspiration has come, in large part, from 10 years of cooperative rhizosphere research in association with leading scientists participating in a regional effort within the southern United States. We have attempted to bring together in this work the major aspects of rhizosphere research and the principles of rhizosphere ecology for the benefit of developing young scientists and technologists, as well as for the established professional researcher and teacher. A prime objective and hope is that this volume might generate ideas that will bring forth new approaches and methodology leading to further advances in our understanding of rhizosphere interactions and their implications for agriculture. ' Because of the enormous complexity of the chemical, physical, and microbiological environment of roots, the methods used by various workers are rarely standardized, but must be devised or modified for each experiment.

Book Description
This book provides an up-to-date overview of the various wood and tree fungi that damage trees, lumber, and timber. Special focus is given to identification, prevention, and remediation techniques, and the book bridges the gap between research and application. It covers the fundamentals of cytology and morphology. There is a more practical section describing damage by viruses and bacteria on trees. The habitats of wood fungi are described as well as tree care. Important tree pathogens and wood decay fungi are characterized for prevention and identification. The final section focuses on the positive effects of wood-inhabiting microorganisms.

Book Description
Fungi play vital roles in all ecosystems, as decomposers, symbionts of animals and plants and as parasites. Thus their ecology is of great interest. It has been estimated that there may be as many as 1. 5 million species of fungi, many of which are still undescribed. These interact in various ways with their hosts, with their substrates, with their competitors (including other fungi) and with abiotic variables of their environment. They show great variation in morphology, reproduction, life cycles and modes of dispersal. They grow in almost every conceivable habitat where organic carbon is available: on rock surfaces, in soil, the sea and in fresh water, at extremes of high and low temperature, on dry substrata and in concen trated solutions. Fungal ecology is therefore an enormous subject and its literature is voluminous. In view of this we have had to be selective in the material we have included in this book. We have chosen to concentrate on subjects in which we have some personal experience through either research or teaching. We preferred to tackle a few subjects in depth instead of attempting to cover a wider range of topics superficially. We are conscious of the extensive gaps in coverage: for example on the ecology of lichens, of fungal plant pathogens and of the complex interactions between fungi and animals. It is some justification that book-length treatments of these subjects are available elsewhere.

Book Description
In the year 2001, Prof. Dr. Ursula Kües was appointed at the Faculty of Forest Sciences and Forest Ecology of the Georg-August-University Göttingen to the chair Molecular Wood Biotechnology endowed by the Deutsche Bundesstiftung Umwelt (DBU). Her group studies higher fungi in basic and applied research. Research foci are on mushroom development and on fungal enzymes degrading wood and their applications in wood biotechnology. This book has been edited to thank the DBU for all support given to the chair Molecular Wood Biotechnology. Contributions to the book are from scientists from Göttingen recognised in different fields of forestry and wood science. Chapters presented by members of the group Molecular Wood Biotechnology introduces into their areas of research. The book is designed for interested students of wood biology and wood technology but will also address scientists in the field.
