摘要

Epichloe endophytes (Epichloe j Neotyphodium species) are an important group of clavicipitaceous fungi that form symbiotic associations (symbiota) with temperate grasses of the Pooideae subfamily (Scott, 2001a; Schaidl, Leuchtmann & Spiering, 2004). These biotrophic fungi systemically colonize the intercellular spaces of leaf primordia, leaf sheaths and culms of vegetative tissue and the inflorescence of reproductive tissues. The asexual Neotyphodium species have no external growth stage and consequently form symptomless associations with their grass host where they are vertically transmitted through the seed following colonization of the developing ovule. Most of the sexual Epichloe species are also transmitted vertically but because of their ability to form external stromata on inflorescence tissue, can also be transmitted horizontally (Leuchtmann & Schardl, 1998; Schardl & Leuchtmann, 1999). The mating system is hetero-thallic (outcrossing) and in nature is mediated by anthomyiid flies {Botanophila spp.), which transfer spermatia between stromata (Bultman et al., 1995; Bultman et al, 1998). Formation of perithecia and release of ascospores into the environment provides a source of vegetative hyphae that give rise to conidia that subsequently infect new hosts, probably by way of colonization of the stigma and style of the host inflorescence (Chung & Schardl, 1997).
