Effects of feeding Kentucky 31 tall fescue seed infected with acremonium coenophialum to laboratory rats.
An endophytic fungus found in Kentucky 31 (KY-31) tall fescue has been associated with the "summer syndrome" (fescue toxicity) in grazing cattle. Four experiments were conducted to investigate the use of weanling rats as an animal model to study the fescue toxicity syndrome. When graded levels of fungus-infected (INF) or fungus-free (FF) KY-31 seed were fed, feed intake and growth rates were in...
متن کاملNovel 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 کاملInfection of Tall Fescue Cultivars with Non-toxic Endophytes
For tall fescue in the southeastern USA, long term persistence, competitiveness, yield, and summer survival are directly related to the presence of a fungal endophyte (Neotyphodium coenophialum; formerly called Acremonium coenophialum) living in the fescue plant. However, cattle grazing forage from the predominant USA tall fescue cultivars infected with their naturally occurring endophyte strai...
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...
متن کاملConsequences For Captive Zebra Finches of Consuming Tall Fescue Seeds Infected With the Endophytic Fungus Acremonium coenophialum
Tall fescue (Festuca rundinacea) plants can be infected with the endophytic fungus Acremonium coenophialum. This fungus, which grows subcutaneously in leaves, stems, and seeds, does not undergo sexual reproduction or sporulate, and cannot survive outside the plant (Clay 1988). The fungus is passed from one generation to the next through infected seed. A mutualistic relationship exists between t...
