Endophytic fungal extracts: evaluation as photosynthesis and weed growth inhibitors

The phytotoxic behaviors based on endophytic fungal extracts may serve as a valuable tool in the further development of a bioherbicide since natural products represent an interesting alternative to replace commercial herbicides.

Tailoring Natural Abenquines To Inhibit the Photosynthetic Electron Transport through Interaction with the D1 Protein in Photosystem II.

The data suggest that this class of compounds interfere at the reducing side of photosystem II, having protein D1 as the most probable target.

Fungal phytotoxins with potential herbicidal activity: chemical and biological characterization.

The isolation and structural and biological characterization of phytotoxins produced by pathogenic fungi for weeds, including parasitic plants, are described and structure activity relationships and mode of action studies are reported to elucidate the herbicide potential of these promising fungal metabolites.

Total Synthesis and Structure Revision of Palmarumycin B6.

The bioassay results showed that the larvicidal activity of palmarumycin B6 with a LC50 value of 32.7 μM was significantly higher than that of its 8-chloro isomer, with an LC50value of 227.3 μM.

Insights in Fungal Bioprospecting in Mexico.

Fungi have consistently been one of the richest sources of natural products, with unprecedented chemical scaffolds and potent biological activities, with the potential for the development of anticancer, antidiabetic, and/or pesticide agents.

Naphthoquinone spiroketals and organic extracts from the endophytic fungus Edenia gomezpompae as potential herbicides.

From the fermentation mycelium of the endophytic fungus Edenia gomezpompae were obtained several phytotoxic compounds including two new members of the naphthoquinone spiroketal family, namely, palmarumycin EG1 and preussomerin EG4, which were unambiguously determined by X-ray analysis.

Evaluation of Herbicidal Potential of Depsides from Cladosporium uredinicola, an Endophytic Fungus Found in Guava Fruit

Two natural products produced by Cladosporium uredinicola, an endophytic fungus isolated from guava fruit, were evaluated for their effects on photosynthesis. Both of them inhibited electron flow

Friedelane triterpenes from Celastrus vulcanicola as photosynthetic inhibitors.

Results from Chl a fluorescence transients in leaves of Lolium perenne and P. ixocarpa suggest that both compounds affect photosynthesis efficiency of the chloroplasts as a response to a process of detoxification and repair, and reduce biomass by more complex mechanisms than only the damaging of the photosynthetic apparatus.

The Sesquiterpenes β-Caryophyllene and Caryophyllene Oxide Isolated from Senecio salignus Act as Phytogrowth and Photosynthesis Inhibitors

It was found that 1 was the most active biomass inhibitor and 1 has a major effect at 72 h after treatment on leaves of P. ixocarpa plants by inhibiting photosystem II (PS II) transforming active reaction centers to “heat sinks” or the formation of silent reaction centers unable to reduce QA.

Endophytic fungi: a source of novel biologically active secondary metabolites * * Paper presented at

It is hypothesize that the interaction fungal endophyte-plant host is characterized by a finely tuned equilibrium between fungal virulence and plant defence, and if this balance is disturbed by either a decrease in plant defence or an increase in fungalvirulence, disease develops.
