The Population Biology of Grass Endophytes

  • A. Leuchtmann

Part of the The Mycota book series (MYCOTA, volume 5B)


The population biology of grass endophytes is uniquely different from that in other groups of fungi given their status (primarily) as mutualistic symbionts, their effects on organisms interacting with hosts, and their variable means of horizontal and/or vertical transmission. Because grass endophytes are biotrophic and form perennial associations with their hosts, population biology of the fungi is tightly connected with that of the host. While the infection of grasses by endophytic fungi has been known for some time, their ecological role was seldom considered in early investigations. The first study that explicitly considered the population biology of endophytes was that of Bradshaw (1959) on Agrostis infected by Epichloë typhina (Pers.) Tul. However, most research has been conducted in the past 10 years, only after the ecological consequences of endophyte infection became widely appreciated.
