Determination of the Ergot Alkaloid Ergovaline in Tall Fescue Seed and Straw Using a QuEChERS Extraction Method with High-Performance Liquid Chromatography-Fluorescence Detection.
Ergovaline is an ergot alkaloid produced by the symbiotic endophyte Epichloë coenophiala, which can colonize varieties of the cool-season grass tall fescue (Festuca arundinacea). It is the principle toxicant responsible for the vasoconstrictive and reproductive sequelae seen in "fescue toxicosis" in livestock which consume forage exceeding the threshold of toxicity established for this compound...
متن کاملTall fescue seed extraction and partial purification of ergot alkaloids
Many substances in the tall fescue/endophyte association (Schedonorus arundinaceus/Epichloë coenophiala) have biological activity. Of these compounds only the ergot alkaloids are known to have significant mammalian toxicity and the predominant ergot alkaloids are ergovaline and ergovalinine. Because synthetically produced ergovaline is difficult to obtain, we developed a seed extraction and par...
متن کاملGenetic Transformation of Elite Turf-type Cultivars of Tall Fescue
Biotechnology approaches can supplement conventional breeding efforts for turfgrass improvement. The objective of this study was to develop reliable transformation and selection schemes for elite turf-type tall fescue cultivars. Transgenic tall fescue (Festuca arundinacea Schreb.) plants were obtained by microprojectile bombardment of embryogenic suspension cells of two elite turf-type cultivar...
متن کاملResponses of Tall Fescue Cultivars to an Irrigation Gradient
particularly in the Intermountain Region. This has led to an increased interest in upgrading privately owned Seasonal availability of water is a major consideration in the manpastures through more intensive management and use agement and selection of plant materials for irrigated pastures in the Intermountain West, USA. Objectives were to evaluate the forage of improved cultivars of perennial g...
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...
