“…vanillae, were isolated, too. The presence of Fusarium as both endophyte and pathogen has been well documented (Bacon and Yates 2006), and we report here and elsewhere (Gamboa-Gaitán 2013) both roles for Fusarium species in vanillas. Another important species complex is Colletotrichum, here represented by C. gloeosporoides and C. boninense, plus an unidentified strain.…”

“…(Hypocreales), although they appeared as endophytes, too. Fungal taxa reported here are new records for endosymbiont mycoflora of vanillas, with the exception of Fusarium oxysporum and Colletotrichum gloeosporoides, which have already been reported as inhabitants of Vanilla (Gamboa-Gaitán 2013, Ordóñez-Castillo 2011, Ordóñez et al 2012, Talubnak and Soytong 2010. Along with Alternaria alternata, Bionectria sp., and Colletotrichum boninense, those taxa are well recognised as plant pathogens, but all of them were recovered from healthy tissues here.…”

Endophytic fungal communities are well-recognised entities within plants worldwide. They hold species with potential in medicinal affairs, biological control of pests, industry, and more. Nevertheless, ecological data about structure and dynamics of endophytic communities are scarce. In this study we sampled root, stem and leaf tissues of Colombian vanilla species in order of both, identifying endosymbionts and characterising the community they belong to. An interesting array of endophytic species was found, including taxa that function as pathogens, saprotrophs, and dermatophytes in other plants/scenarios. Ecological parameters show a moderate diversity with a lognormal arrangement of species quite similar to communities of macroorganisms. Many species here reported belong to taxa broadly reported as sources of biologically active compounds, so they are good candidates for bioprospecting research.

The influence of culture fluid of a yeast-like fungus, melanin producer Pseudonadsoniella brunnea (Meripilaceae, Agaricomycotina) on pathogenic fungi of the genus Gibberella (anamorph of Gibberella fujikuroi, i.e.: Fusarium verticillioides) (Nectriaceae, Ascomycotina) is studied by using the agar diffusion method. The stable fungicidal effect of Ps. brunnea culture fluid on pathogenic fungi investigated found to be present. The diameter of the zones of absence of growth of test cultures of pathogenic fungi, those testified the fungicidal impact of Ps. brunnea culture fluid, found to be similar to the action of biocides belonging to the class of quaternary ammonium compounds (benzalkonium chloride).

Antioxidant activity of exo‐metabolites produced by Fusarium oxysporum: An endophytic fungus isolated from leaves of Otoba gracilipes

Tropical ecosystems hold an extremely diverse array of endophytic fungi, but their potential use still remains to be explored. In this study, we isolated an endophytic fungus from the leaves of Otoba gracilipes, a medicinal tree from a tropical rainforest in Colombia. Following isolation and cultivation, we evaluated its extracellular crude extract for antioxidant activity. Using traditional and molecular methods (ITS1, NL1 regions), the endophyte was identified as Fusarium oxysporum. Fresh spores from the fungal isolate were inoculated in liquid media (potato dextrose broth [PDB] and potato dextrose–yeast extract broth [PDYB]) and centrifuged for recovering extracellular polysaccharides from the exhausted medium after 30 days of cultivation. Crude extracts were recovered, purified, lyophilized, and evaluated for their ability to inactivate the free radical 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH). The extracts obtained from PDB culture media had a 51.5% of scavenging effect on DPPH after 5 min of reaction compared with the extracts from PDBY (26.4%), which suggests a high antioxidant potential of these fungal extracts. Thus, our results suggest other fungi from tropical ecosystems should be explored as potential sources of novel enzymes and other metabolites with bioactivity.
