Neotyphodium in Cool-Season Grasses

Craig A. Roberts, Charles P. West, Donald E. Spiers

ISBN: 978-0-470-38469-5 February 2008 Wiley-Blackwell 379 Pages


Divided into logical easy-to-use sections, Neotyphodium in Cool-Season Grasses is an up-to-date anthology of the latest knowledge on the genus Neotyphodium. This thorough text covers the molecular biology of Neotyphodium endophytes and their effects on grass hosts, invertebrate and vertebrate herbivores, and the plant communities in which they interact. The expert editors also include information on the commercial uses of endophytes in livestock and turf industries.

Researchers and teachers in grass research, extension, agronomy, and animal toxicology, and university libraries with courses in these subjects should not be without this important text.

Proposed Educational Approaches

"The book will be useful to researchers, educators, and extension specialists as a "one-stop shopping" opportunity into endophyte biology." Thomas L. Bultman, Biology Department, Hope College, Holland, MI in Crop Science, January-February 2006.

"In sum, Neotyphodium in Cool-Season Grasses is an excellent collection of recent literature that those working with pasture of turf grass will want to have on their shelf. In addition, plant and fungal ecologists who seek to learn more about the fascinating grass endophytes will find Neotyphodium in Cool-Season Grasses an excellent starting place." Thomas L. Bultman, Biology Department, Hope College, Holland, MI in Crop Science, January-February 2006.
