Infection 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 کاملQuantification of ergovaline using HPLC and mass spectrometry in Iranian Neotyphodium infected tall fescue
Ergovaline, the main ergopeptine alkaloid produced in tall fescue (Fescue arundinacea Schreb.) infected with endophyte (Neotyphodium coenophialum Morgan- Jones & Gams), is known to cause tall fescue toxicosis. This study was conducted to examine the presence of fungal endophytes in five populations of tall fescue collected from various regions of Iran. The existence of Neotyphodium mycelia in t...
متن کاملGenetic diversity of Neotyphodium fungal endophytes in three Iranian grass species using AFLP molecular markers
Genetic diversity of fungal endophytes, Neotyphodium species, was studied in grasses Festuca arundinacea, F. pratensis and Lolium perenne using AFLP markers. Fungi were isolated from the host leaf sheaths and Neotyphodium species were selected based on morphological characteristics. To confirm identity of selected fungi belonging to the genus Neotyphodium, polymerase chain reaction was perform...
متن کاملPhysiological and digestive effects of Neotyphodium coenophialum-infected tall fescue fed to lambs.
The digestive responses and degradation of ergovaline and production of lysergic acid in the rumen of sheep offered Neotyphodium coenophialum-infected tall fescue straw at 2 ergovaline levels were investigated. Six crossbred wethers (56 +/- 3.0 kg of BW) were used in a randomized crossover design involving 2 treatments, for a total of 6 observations per treatment. The experiment consisted of tw...
متن کاملGenetic diversity in a world germplasm collection of tall fescue
Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated that it contains different species from the genus Festuca and allowed their rapid classification into the three major morphotypes (Continental, Mediterranean and Rhizomatous...
