Endophytic fungi belonging to the Balansieae tribe were first hypothesized to cause poor livestock performance in 1977 and, in 1980, the association was validated. The fungi were extensively studied and classified according to morphology, their life cycles exam- ined to determine methods to eliminate the fungi in grasses, and practical methods devel- oped for livestock producers to eliminate endophyte-infected plants from pastures and establish endophyte-free plants. Hindsight illustrates how primitive was our understanding of the associations between endophyte, grass plant, and animal. The plant/endophyte asso- ciations, thought to be rare cases, have now been identified in grasses that are adapted from tropical to nearly arctic, and from marshland to desert climatic regimes.In the two decades that have passed since the first endophyte-plant-animal associa- tion was made, the scientific community has re-classified the endophytic fungi twice (now the genus Neotyphodium), ~he systematics and ecological role of endophytes have been more clearly defined, endophytes and grasses are now generally accepted as mutualistic symbionts, the chemistry of toxins and their functions defined, beneficial effects of endo- phytes on plants identified, and commercial ventures have emerged based upon endophyte research in the turfgrass and livestock industries.

Examining intercellular infections in certain plant species that lead to a symbiotic relationship between the host and its endophytic microbes, this volume demonstrates the ability of many types of endosymbionts, acting as a unit with hosts to better survive, compete and reproduce. Practical applications of such endophytes are also discussed, for example, pharmaceutical developments and agricultural management.

This reference analyzes the ecology, evolution, genetics, physiology, and taxonomy of this diverse group of fungi for identification of common biological, biochemical, and genetic features and discovery of potential medical and agricultural applications. It traces and reconstruct the evolution of various host-endoparasite systems and studies recent taxonomic research and DNA sequence analyses on plant-infecting clavicipitaleans. Providing a holistic view of the entire clavicipitalean family, the book compares morphologic, geographic, and host variations among various clavicipitalean populations and examines key discoveries and compounds obtained in clavicipitalean studies.

This book considered the biological, ecological, toxicology, and chemical aspects of research topics as they relate to endophytes of grasses. Several chapters reflect the very pragmatic applications of endophytes and endophyte-infected grasses. Other chapters offer future applications for endophytes and are therefore discussed from theoretical viewpoints. This book contains the collective writings of an international group of experts on fungal endophytes of grasses, all of whom are directed toward, understanding, creating, and exploiting the positive aspects of endophytes. With this book, we are attempting to stimulate and facilitate future explorations of the grass endophytes.
