| Abstract/Contents: | "Fungal endophytes were isolated from 16 plants obtained from 11 populations of Festuca arizonica. Sequences of rRNA gene segments indicated that most were "e-endophytes"--closely related to the grass choke pathogen, Ephichloe typhina (anamorph = Acremonium typhinum). Three distinct e-endophyte sequences were obtained (e1, e2, and e3), and compared with five E. typhina sequences for phylogenetic analysis. The results indicated at least two separate evolutionary origins of the F. arizonica e-endophytes. The most common type (e1) was related to E typhina from Festuca rubra, a European grass. The others were related to a Poa ampla choke pathogen from Alaska. One of the plants surveyed simultaneously hosted e3 and a second, non-Acremonium endophyte, which was designated "p-endophyte." World-wide surveys of related grass species also identified individual plants which hosted seed-borne p- and e-endophytes either separately, or in combination. The ecological fitness and adaptability of F. arizonica and other grasses may be enhanced by the diversity of endophytes that they possess." |
