Effects of Neotyphodium fungi on Lolium multiflorum seed germination in relation to water availability.
BACKGROUND AND AIMS Temperate endophyte-infected (Neotyphodium sp.) grasses have been shown to exhibit an ecological advantage over endophyte-uninfected grasses under abiotic stressful conditions. It is predicted that endophyte-infected plant populations will display higher rates of germination and proportion of germinated seeds under limiting water conditions. METHODS The hydrotime regressio...
متن کاملSurvey and Detection of Endophytic Fungi in Lolium Germ Plasm by Direct Staining and Aphid Assays
Wilson, A. D., Clement, S. L., and Kaiser, W. J. 1991. Survey and detection of endophytic fungi in Lolium germ plasm by direct staining and aphid assays. Plant Dis. 75:169-173. Clavicipitaceous anamorphic endophytes were detected in 28 of 85 accessions from five of eight species in a collection of Lolium germ plasm. Comparative descriptions of endophytic mycelium in seeds of L. multiflorum, L. ...
متن کاملFlavonoids, benzoic acids and cinnamic acids isolated from shoots and roots of Italian rye grass (Lolium multiflorum Lam.) with and without endophyte association and arbuscular mycorrhizal fungus
Phenolic compounds present in Lolium multiflorum Lam. were isolated and characterized. Significant differences in their distribution were found, in shoots and roots of plants with (Lmþ) and without (Lm ) endophyte association, grown with (Micþ) and without (Mic ) mycorrhizal fungi Glomus intraradices, indicating a systemic effect of these microorganisms on the phenolics metabolism of L. multifl...
متن کاملتأثیر قارچ‌های اندوفایت در بهبود ویژگی‌های فنوتیپی فسکیوی بلند (Festuca arundinacea Schreb.) و فسکیوی مرتعی (Festuca pratensis Huds.) بومی ایران
A symbiotic relationship exists between the endophytic fungi of the genus Neotyphodium and many cool-season grasses. Endophytes can alter the growth as well as morphological and physiological characteristics of the host plant, thereby influencing the persistence and survival rate of infected plants. This study was conducted to evaluate the effects of endophyte on phenotypic characteristics of I...
متن کاملEndophytic fungi in indigenous Australasian grasses associated with toxicity to livestock.
Grazing of Echinopogon spp. by livestock in Australia has caused symptoms similar to those of perennial ryegrass staggers. We observed an endophytic fungus in the intercellular spaces of the leaves and seeds of New Zealand and Australian specimens of Echinopogon ovatus. Culture of surface-sterilized seeds from New Zealand specimens yielded a slow-growing fungus. An examination in which immunobl...
