Acremonium Endophytes in Mediterranean Tall Fescue
There is a growing awareness among plant scientists that clavicipitaceous anamorphic endophytes infecting grasses constitute a valuable genetic resource (microbial germplasm) for use in improving forage and turf grass performance (Clement et al 1994, Wilson 1996). The pool of endophyte diversity needed for developing more suitable grassendophyte combinations for livestock production and pest resistance may reside in USDA-ARS repository collections. Seeds in United States repositories are known to harbor endophytes, as evidenced by recent surveys of small portions of Festuca, Lolium, and perennial Hordeum collections (Springer and Kindler 1990, Wilson et al. 1991a, b, Holder et al. 1994). However, presence of endophyte-infected accessions in these collections is generally low, suggesting little potential for selecting beneficial endophytes for improving grasses (see West et al., 1993).
