Infection of Tall Fescue Cultivars with Non-toxic Endophytes
نویسنده
چکیده
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 strains (E+) suffer from a condition called "Fescue Toxicosis". Occurrence of fescue toxicosis is associated with the presence of this endophytic fungus.

Host status of endophyte-infected and noninfected tall fescue grass to Meloidogyne spp.
Tall fescue grass cultivars with or without endophytes were evaluated for their susceptibility to Meloidogyne incognita in the greenhouse. Tall fescue cultivars evaluated included, i) wild-type Jesup (E+, ergot-producing endophyte present), ii) endophyte-free Jesup (E-, no endophyte present), iii) Jesup (Max-Q, non-ergot producing endophyte) and iv) Georgia 5 (E+). Peach was included as the con...
متن کاملTall fescue cultivar and fungal endophyte combinations influence plant growth and root exudate composition
Tall fescue [Lolium arundinaceum (Schreb.)] is a cool-season perennial grass used in pastures throughout the Southeastern United States. The grass can harbor a shoot-specific fungal endophyte (Epichloë coenophiala) thought to provide the plant with enhanced resistance to biotic and abiotic stresses. Because alkaloids produced by the common variety of the endophyte cause severe animal health iss...

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 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...

Mutual relationship between pasture grasses and Neotyphodium fungal endophytes is of great importance in grass improvement. Two endophyte containing tall fescue genotypes (75 and 83) and their endophyte free ramets were used in this study. Endophytes were isolated from tall fescue genotypes 75 and 83 and used in three methods of inoculation including Latch and Christensen approach, insertion of...
