Defense mechanisms against fungi in bark, xylem, roots, and foliage of woodyangiosperms and gymnosperms are addressed in this newest addition to the SPRINGER SERIES IN WOOD SCIENCE. The topic is approached from an anatomical and physiological perspective with emphasis on the relationships betweenplant structure and function and their role in defensive reactions and woundrepair. Contributions on the biochemistry of defensive reactions, in-depth treatises on specific diseases such as Dutch elm disease, Hypoxylon canker of aspen, and Fusiform rust of pines, as well as chapters on wound reactions in bark tissues, microenvironmental aspects of xylem decay, the role of mycorrhizzal fungi in defense, physiological responses of trees to fungal symbionts of insects, and the application of tissue culture and immunocytochemistry to the study of defense mechanisms in trees are included. One of the most significantfeatures of the book is the large complement of photographic plates which serves to bring together a plethora of histopathological data.
