Cytotoxic prenylated indole alkaloid produced by the endophytic fungus Aspergillus terreus P63
(Elsevier B.V., 2019-08-01)
Prenyl indole alkaloids constitute a diverse class of natural products with complex chemical structures and potent biological activities. Investigation of the growth medium EtOAc extract produced by the endophytic fungus ...
Metabolism or behavior: explaining the performance of aphids on alkaloid-producing fungal endophytes in annual ryegrass (Lolium multiflorum)
(Springer, 2017-10)
Plant–herbivore interactions are often mediated by plant microorganisms, and the “defensive mutualism” of epichloid fungal endophytes of grasses is an example. These endophytes synthesize bioactive alkaloids that generally ...
Monitoring indole alkaloid production by Penicillium digitatum during infection process in citrus by Mass Spectrometry Imaging and molecular networking
(2019-08-01)
Green mold, caused by Penicillium digitatum, is the most destructive post-harvest disease in citrus. Secondary metabolites produced by fungal phytopathogens have been associated with toxicity to their respective host through ...
Mutualism effectiveness of a fungal endophyte in an annual grass is impaired by ozone
(Wiley Blackwell Publishing, Inc, 2016-02)
Ozone is an increasing tropospheric contaminant of climate change. Exposure to ozone may affect the symbiotic relationship between plants and beneficial microorganisms. In particular, the herbivore resistance mechanism ...
Ontogenetic and trans-generational dynamics of a vertically transmitted fungal symbiont in an annual host plant in ozone-polluted settings
(Wiley Blackwell Publishing, Inc, 2020-10)
Tropospheric ozone is an abiotic stress of increasing importance in the context of global climate change. This greenhouse gas is a potent phytotoxic molecule with demonstrated negative effects on crop yield and natural ...
The plant hormone salicylic acid interacts with the mechanism of anti‐herbivory conferred by fungal endophytes in grasses
(Wiley Blackwell Publishing, Inc, 2018-02)
The plant hormone salicylic acid (SA) is recognized as an effective defence against biotrophic pathogens, but its role as regulator of beneficial plant symbionts has received little attention. We studied the relationship ...
Chemical ecology mediated by fungal endophytes in grasses
(Springer, 2013-08)
Defensive mutualism is widely accepted as providing the best framework for understanding how seed-transmitted, alkaloid producing fungal endophytes of grasses are maintained in many host populations. Here, we first briefly ...
New alkaloids from a hawaiian fungal strain Aspergillus felis FM324
(Frontiers Media, 2022)
Occurrence of Alkaloids in Grass Seeds Symbiotic With Vertically-Transmitted Epichloë Fungal Endophytes and Its Relationship With Antioxidants
(Frontiers Media SA, 2018-12)
Host organisms can acquire new functional traits through symbiosis. Seed-transmitted Epichloë fungal endophytes are known to protect host plants against herbivores and increase tolerance to abiotic stresses by alkaloids ...
Jasmonic acid regulation of the anti-herbivory mechanism conferred by fungal endophytes in grasses
(Wiley Blackwell Publishing, Inc, 2018-11)
The most studied mechanism of protection against herbivores in grasses associated with Epichloë fungal endophytes has been the fungal production of alkaloids. However, the contribution of the plant immune response on the ...
