Novel Endophyte-Infected Tall Fescue
Tall fescue (Schedonorus phoenix (Scop.) Holub) is a cool season perennial grass that fills a critical forage produc-tion gap in the Southeast and is the predominant forage crop in much of the U.S. In fact, this species is the most widely used grass in improved U.S. pastures, occupying more than 36 million acres. Its popularity is related to establishment ease, drought tolerance, excellent graz...
متن کاملMicroarray analysis of endophyte-infected and endophyte-free tall fescue.
Many grasses have mutualistic symbioses with fungi of the family Clavicipitaceae. Tall fescue can harbor the obligate endophyte, Neotyphodium coenophialum that is asexually propagated and transmitted via host seeds. Total RNA was isolated from pseudostems of known endophyte-infected (E+) and endophyte-free (E-) plants and tested in triplicate on the Affymetrix Wheat Genome Array GeneChip and Ba...

Tall fescue (Festuca arundinacea Schreb.) is an important forage resource for beef (Bos taurus L.) production in the North–South transition zone. Recently, the cultivar ‘Jesup’ was released to provide improved stand survival when infected with a novel (nontoxic) endophyte marketed as MaxQ (Pennington Seed, Madison, GA), and warrants evaluation as a source of winter hay for beef cattle. Intake a...
متن کاملPerformance of growing cattle grazing stockpiled Jesup tall fescue with varying endophyte status.
The objective of this study was to evaluate the performance of growing cattle when intensively grazing stockpiled endophyte-infected (E+), endophyte-free (E-), and nontoxic endophyte-infected (EN) tall fescue during the winter. The experiment was conducted over 5 consecutive winters. In each year, plots (1 ha each, 4 per treatment) were harvested for hay in August, fertilized in September, and ...
متن کاملEconomic Analysis of Replacing Endophyte-Infected with Endophyte-Free Tall Fescue Pastures
lengthened gestation terms (Waller and Fribourg, 2002; Hemken et al., 1979). The U.S. economic loss in beef Cattle (Bos taurus) consuming tall fescue pastures infected with the associated with this endophyte was estimated at over endophyte Neotyphodium coenophialum often suffer physiological disorders that reduce animal performance. One solution is to replace $600 million annually (Hoveland, 19...
