Understanding factors that affect the context dependency of species interactions has been identified as a critical research area in ecology. The presence of symbionts in host plants can be an important factor influencing the outcome of plant-insect interactions. Similarly, herbivore identity can alter the outcome of plant-symbiont interactions. Symbiotic foliar fungal endophytes confer resistan...
Competitive outcomes among plants can vary in different abiotic and biotic conditions. Here we tested the effects of two phylotypes of Alternaria endophytes on the growth, competitive effects, and competitive responses of the exotic invasive forb Centaurea stoebe. Centaurea stoebe was a better competitor against North American grass species than grasses from its European home range in the absen...
Endophytes are microorganisms that live within plant tissues without causing symptoms of disease. They are important components of plant microbiomes. Endophytes interact with, and overlap in function with, other core microbial groups that colonize plant tissues, e.g., mycorrhizal fungi, pathogens, epiphytes, and saprotrophs. Some fungal endophytes affect plant growth and plant responses to path...
Festuca rubra subsp. pruinosa is a grass that grows on coastal cliffs along the Atlantic coast of Europe. Asymptomatic plants of this species are systemically infected by the fungal endophyte Epichloë festucae. It is not known whether the alkaloids ergovaline and peramine are produced by the endophyte in Festuca rubra subsp. pruinosa. Plants from four populations were collected from the norther...
Abstract Temple trees, including the gymnosperm Platycladus orientalis and angiosperm Styphnolobium japonicum , have been planted in China for thousands of years. Tree age thus varies widely from young to ancient trees. Foliar endophytes P. S. were surveyed this exploratory study that was based on isolation into culture sequencing fungi trees varying 10 5000 years ( ) 1700 ). Sequenced belonged...
The fungal endophytes of Australian myco-heterotrophic orchids are largely unknown. In this investigation we identified the fungal endophytes of three species of Australian myco-heterotrophic orchid: the terrestrial species Dipodium variegatum and Dipodium hamiltonianum and the vine-like Erythrorchis cassythoides. Similar to studies of myco-heterotrophic orchids in Nth America and Europe the fu...
Interactions between leaf-cutting ants, their fungal symbiont (Leucoagaricus) and the endophytic fungi within the vegetation they carry into their colonies are still poorly understood. If endophytes antagonistic to Leucoagaricus were found in plant material being carried by these ants, then this might indicate a potential mechanism for plants to defend themselves from leaf-cutter attack. In add...
Almost all plant species form symbioses with soil fungi, and nutrient transfer to plants is largely mediated through this partnership. Studies of fungal nutrient transfer to plants have largely focused on the transfer of limiting soil nutrients, such as nitrogen and phosphorous, by mycorrhizal fungi. However, certain fungal endophytes, such as Metarhizium and Beauveria, are also able to transfe...
