Liver cytochrome P450 system as affected by endophyte-infected tall fescue seed extracts and ergot alkaloids
Endophyte infected tall fescue (E+) is the base diet for nearly all beef cattle in the southern USA. It has been linked to a variety of toxicological conditions due to the presence of large numbers of ergot alkaloids. This study was designed to investigate the effects of E+ seed extract and selected ergot alkaloids on the detoxification pathway by cytochrome P450 (CYP3A4) enzyme system. Tests w...
متن کاملmineralogical changes in clay-sized phlogopite and muscovite as affected by endophyte-tall fescue symbiosis
abstract the association between neotyphodium spp. endophytes and cool-season grasses, particularly tall fescue (festuca arundinacea, schreb), represents a widespread type of mutualism in nature. numerous researches were performed about positive effect of symbiosis on plant resistance to different stresses but the role of symbiosis on nutrients uptake particularly potassium uptake and k-bearing...
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 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 کاملEffects of soil contamination by trace elements on white poplar progeny: seed germination and seedling vigour.
Seed germination is considered a critical phase in plant development and relatively sensitive to heavy metals. White poplar (Populus alba) trees tend to accumulate Cd and Zn in their tissues. We tested if soil contamination can affect P. alba progeny, reduced seed germination and explored the distribution of mineral elements in the seed. For this purpose, fruits and seeds from female P. alba tr...
