Genetic diversity of fungal endophytes, Neotyphodium species, was studied in grasses Festuca arundinacea, F. pratensis and Lolium perenne using AFLP  markers. Fungi were isolated from the host leaf sheaths and Neotyphodium species were selected based on morphological characteristics. To confirm identity of selected fungi belonging to the genus Neotyphodium, polymerase chain reaction was perform...

1. Flood-sensitive plant species are restricted to highly elevated sites in floodplains, but why flood-tolerant plants do not grow at higher elevations is much less clear. We test the hypothesis that a trade-off exists between flood-tolerance and selective root placement in nutrient-rich patches, a putatively important trait in the more competitive highly elevated sites. 2. Achillea ptarmica , ...
