| Abstract/Contents: | "Fungal endophytes of genus Neotyphodium have long been known to inhabit the internal tissues of plants without producing external reproductive structures on plants. For these endophytes, infection of the embryo within the seed has been the accepted mode of transmission. In this study, we examined several species of endophyte-infected grasses, including Bromus setifolius, Festuca ovina, F. rubra, and Poa ampla, and documented the presence of epiphyllous mycelial nets on their leaves. To evaluate whether the epiphyllous nets belong to the endophytes, we isolated the epiphyllous mycelium from the surfaces of Poa ampla leaves and analyzed it by DNA sequencing and microscopy. DNA isolates from wax peels showed that the epiphyllous net belonged to the endophyte, Neotyphodium typhinum. The mycelial nets produced by the clavicipitaceous endophytes may play a role in defense of host plants from potential pathogens through 'niche exclusion'. The production of conidia on epiphyllous mycelia suggests that the endophyte may also have the opportunity for contagious spread to uninfected plants through epiphyllously-produced conidia." |
