In defensive ant-plant interactions myrmecophytic plants express reduced chemical defense in their leaves to protect themselves from pathogens, and it seems that mutualistic partners are required to make up for this lack of defensive function. Previously, we reported that mutualistic ants confer plants of Acacia hindsii protection from pathogens, and that the protection is given by the ant-asso...

Interactions among endophytic fungi, woody plants and herbivores are usually studied emphasizing fungal mediated plant-herbivore interactions. Seeking evidence for indication of causal relationships between fungi and herbivores sharing the host plant has been self-feeding reasoning in endophyte literature since the findings that some endophytes, particularly seed-borne grass-endophytes in agron...

Symbiotic associations can be disrupted by disturbance or by changing environmental conditions. Endophytes are fungal and bacterial symbionts of plants that can affect performance. As in more widely known symbioses, acute or chronic stressor exposure might trigger disassociation of endophytes from host plants. We tested this hypothesis by examining the effects of oil exposure following the Deep...

Fungi that occur inside asymptomatic plant tissues are known as fungal endophytes. Different genera of fungal entomopathogens have been reported as naturally occurring fungal endophytes, and it has been shown that it is possible to inoculate plants with fungal entomopathogens, making them endophytic. Their mode of action against insects appears to be due to antibiosis or feeding deterrence. Res...

Coffee (Coffea arabica) plant tissues were surface-sterilized and fungal endophytes isolated using standard techniques, followed by DNA extraction and sequencing of the internal transcribed spacer region (ITS). A total of 843 fungal isolates were recovered and sequenced (Colombia, 267; Hawai’i, 393; Mexico, 109; Puerto Rico, 74) yielding 257 unique ITS genotypes (Colombia, 113; Hawai’i, 126; Me...

Plants are colonized by diverse assemblages of fungal endophytes that have potential as biocontrol agents for a variety of crops, including grapevine. Although the diversity of symbionts can be very high in wild plants, the fungal endophytes of wild Vitis plants have not yet been investigated. We surveyed the fungal endophytes of 6 wild populations of Vitis riparia, as well as a cold-tolerant, ...

The incorporation of entomopathogenic fungi as biocontrol agents into Integrated Pest Management (IPM) programs without doubt, has been highly effective. The ability of these fungal pathogens such as Beauveria bassiana and Metarhizium anisopliae to exist as endophytes in plants and protect their colonized host plants against the primary herbivore pests has widely been reported. Aside this sole ...

Endophytes are microbes that inhabit host plants without causing disease and are reported to be reservoirs of metabolites that combat microbes and other pathogens. Here we review diverse classes of secondary metabolites, focusing on anti-microbial compounds, synthesized by fungal endophytes including terpenoids, alkaloids, phenylpropanoids, aliphatic compounds, polyketides, and peptides from th...

The growth and development of rice (Oryzae sativa) seedlings was shown to be regulated epigenetically by a fungal endophyte. In contrast to un-inoculated (nonsymbiotic) plants, endophyte colonized (symbiotic) plants preferentially allocated resources into root growth until root hairs were well established. During that time symbiotic roots expanded at five times the rate observed in nonsymbiotic...
