Consequences 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...
متن کاملEffects 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 کاملImpact of endophytic fungi on seed and seedling characteristics in tall and meadow fescues
Tall fescue and meadow fescue are naturally infected with fungal endophytes, Neotyphodiumcoenophialum and Neotyphodium uncinatum, respectively. Seed traits are an important measureof the effects of the endophytic fungi which has been less addressed. In this study we usedendophyte-infected (EI) and endophyte-free (EF) clones of tall and meadow fescue genotypes inthe field to investigate the effe...
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 کاملExpression of Russian Wheat Aphid (Homoptera: Aphididae) Resistance in Genotypes of Tall Fescue Harboring Different Isolates of Acremonium Endophyte
J. Econ. Entomol. 89(3): 76C-770 (1996) ABSTRACT Experiments were conducted to compare the expression of Russian wheat aphid, Diurnphis noxia (Mordvilko), resistance in 2 genotypes of tall fescue grass, Festucn arun&nacea Schreb., harboring different isolates of the endophytic fungus Acremonium coenophialum Morgan-Jones & cams. Aphids did not select endophyte-free over endophyte-infected tiller...
