Fungal Endophytes in Asclepias 公开

Abstract

Interest in the ecological importance and presence of fungal endophytes, generally non-pathogenic fungi that live inside plant tissues, has increased among scientists in recent years. Studies of endophytes in plants from the equator to the arctic, and from tropical trees to agricultural grasses, demonstrate the remarkably widespread nature of fungal endophyte infection. This thesis project focuses on the cultivation and identification of fungal foliar endophytes, fungal endophytes found growing within leaves, in four Asclepias (milkweed) species: A. curassavica, A. incarnata, A. syriaca, and A. tuberosa. Incidence and prevalence of endophytes, as well as composition of the fungal endophyte communities in the four species are compared and discussed. Results indicate a diverse community of fungal foliar endophytes within the leaves for Asclepias. I discuss the implications for milkweed-herbivore interactions.
