Within this book, readers will find chapters that address anatomical and physiological responses of bark and xylem to mechanical injuries and invasion by fungi. Response mechanisms in angiosperm and gymnosperm roots, stems and leaves are presented in several chapters that integrate information on how trees, as whole organisms, defend and repair themselves. There are comprehensive chapters on specific tree pathogens that have received considerable research attention over the years, including Ophiostoma ulmi, Cronartium quercuum f. sp. fusiforme and Hypoxylon mammatum. These diseases have served, and continue to serve, as model systems for studying vascular wilts, rust and canker diseases. In addition, important factors contributing to disease, such as plant-water relations and microenvironmental aspects of wounded and colonized tissues, are discussed within this volume. New approaches to studying tree defenxe reactions also are included and will be found in chapters covering molecular, tissue culture and immunocytochemical aspects. How trees respond to fungi associated with insects and the role of mycorrhizae in protecting tree roots against fungal pathogens are important contributions that expand the coverage of this book. The classic early work has been included in the first chapter with a historical perspective that reflects how much these early investigations still have to offer.
