A symbiotic relationship exists between the endophytic fungi of the genus Neotyphodium and many cool-season grasses. Endophytes can alter the growth as well as morphological and physiological characteristics of the host plant, thereby influencing the persistence and survival rate of infected plants. This study was conducted to evaluate the effects of endophyte on phenotypic characteristics of I...
Fescue is an important forage species growing in wide climates. Genetic variation was estimated for 18 accessions of Festuca arundinacea using 12 ISSR primers in payame Noor university of Kermanshah. In total 87 bands (loci) were obtained.77 bands out of 87 were polymorph in accessions. The mean polymorphism percentage was 89.05 among Fescue accessions.The greatest polymorphism percentage were ...
Previous research has implicated an endophytic fungus as being associated with fescue toxicity (summer syndrome) in cattle grazing Kentucky 31 tall fescue (Festuca arundinacea Schreb.) pastures. Hay and seed were harvested from Kentucky 31 pastures known to be either fungus-free or heavily infested with an endophytic fungus identified as Acremonium coenophialum Morgan-Jones and Gams. Four diets...

Abstract The lack of turfgrass diversity in cool‐season sod production is related to information inefficiencies, such as the agronomic available on improved, low‐input species, fine fescues ( Festuca spp.). Collaborative research between Purdue University and Minnesota investigated influence species mixtures harvest (production strength) storage limitations sod. Field experiments were establish...
Jennifer A. Rudgers*, Jennifer M. Koslow and Keith Clay Department of Biology, Indiana University, Bloomington, IN 47405, USA *Correspondence: E-mail: [email protected] Abstract Recent studies have expanded research on biodiversity by investigating whether the effects of diversity on ecosystem functioning hinge on the presence of symbiotic microorganisms. Cool-season grasses commonly harbour...
Eight cultivars of tall fescue (Lolium arundinaceum Schreb., S.J. Darbyshire 1⁄4 Festuca arundinacea Schreb.), Barcel, Kenhy, Kentucky-31, Missouri-96, Mozark, Stargrazer, C-1 (an experimental selection), and HiMag, were sampled at 2-h intervals during daylight on four cutting dates. Cultivars varied in concentrations of carbohydrate fractions but accumulation rates were not different. Daily me...
Four primary mycotoxicosis have been reported in livestock caused by fungal infections of grasses or cereals by members of the Clavicipitaceae family. Ergotism (generally associated with grasses, rye, triticale and other grains) and fescue toxicosis (associated with tall fescue grass, Festuca arundinacea) are both caused by ergot alkaloids, and referred to as 'ergot alkaloid intoxication'. Ryeg...
Tasco-Forage is an Ascophyllum nodosum seaweed-based product that has increased antioxidant activity in both plants and animals. Endophyte (Neotyphodium coenophialum ([Morgan-Jones and Gams] Glenn, Bacon, and Hanlin)-infected and uninfected tall fescue (Festuca arundinacea Schreb.) pastures in Virginia and Mississippi during 1997 were treated or not with 3.4 kg Tasco/ha in April and July. There...
