“…The genera Cladosporium, Trichoderma, Diaporthe, Phoma, and Alternaria isolated in this study can be used as antagonistic agents against phytopathogenic fungi. Cladosporium sp., Aspergillus sp., Nigrospora sp., Fusarium p., Trichoderma sp., Chaetomium sp., Alternaria sp., Paecilomyces sp., and Phyllostica are often isolated as endophytic fungi in several agricultural and native plant species (Azevedo, 1998;Rubini et al, 2005;Guo et al, 2008;Veja et al, 2008;Gazis and Chaverri, 2010;Kurose et al, 2012;Parsa et al, 2016).

Potential of endophytic fungi as biocontrol agents of Duponchelia fovealis (Zeller) (Lepidoptera:Crambidae)

et al. 2017

This study reports the first assessment of endophytic fungi isolated from strawberry leaves and selection of isolates for the control of Duponchelia fovealis, a new pest of strawberries. A total of 400 strawberry leaves of the cultivar 'Albion' were collected in four commercial farms. Leaves were disinfected, cut in fragments, and placed on Petri dishes containing potato dextrose agar media with tetracycline and incubated for 30 days. Following this time, 517 fungal colonies were isolated, and thirteen genera were identified: Cladosporium, Aspergillus, Nigrospora, Fusarium, Trichoderma, Chaetomium, Alternaria, Paecilomyces, Penicillium, Ulocladium, Bipolaris, Diaporthe, and Phoma. Eight isolates belonging to the genera Aspergillus, Diaporthe, Paecilomyces, and Cladosporium were selected for pathogenicity bioassays against third instar larvae of D. fovealis. Isolates of Paecilomyces induced the highest mortality rates.

“…For example, the fungus Eudarluca caricis has been shown to parasitize rust fungi on the outer surfaces of leaves (Nischwitz et al 2005), and the fungal leaf pathogen Stachybotrys cylindrospora produces mycotoxins that can negatively affect other pathogens (Ayer and Miao 1993). Direct effects could also occur in the opposite direction (Kurose et al 2012). For example, leaf endophytes could increase disease severity by producing a compound that would otherwise be limiting to pathogen growth.…”

“…For example, Penicillium could degrade different cell wall constituents such that Drepanopeziza and Penicillium complement or even synergize with each other in degrading the apoplast more thoroughly. These potential interactions between fungal leaf endophytes, pathogens, and their plant hosts have not been explicitly tested, but a recent study has also highlighted the ability of endophytes to increase pathogenic aggressiveness (Kurose et al 2012). …”

Leaf endophytes and Populus genotype affect severity of damage from the necrotrophic leaf pathogen, Drepanopeziza populi

et al. 2013

Abstract. Fungal leaf endophytes-nonpathogenic microfungi that live within plant leaves-are ubiquitous in land plants. Leaf endophytes and host plant genotypes may interact to determine plant disease severity. In a greenhouse inoculation experiment, we found that leaf endophyte species and Populus angustifolia genotypes both affected disease outcomes in plants inoculated with the necrotrophic leaf pathogen Drepanopeziza populi. Contrary to many studies showing endophytes conferring defense, all plant genotypes inoculated with the endophyte Penicillium sp. prior to inoculation with the pathogen D. populi were characterized by greater pathogen symptom severity than plants inoculated with the pathogen only. We quantified defense gene expression via qRT-PCR, but found no evidence that increased pathogen damage was related to differential expression of the assayed genes. A second endophyte, Truncatella angustata, which was previously found to reduce symptom severity of the biotrophic pathogen Melampsora in Populus trichocarpa, did not affect symptom severity of the necrotrophic pathogen D. populi or defense gene expression. Overall, our study highlights the variable effects of endophytes on pathogen symptom severity, and illustrates that plant genotypic variation can remain important for disease outcomes even in the presence of endophytes altering disease. Additional work is needed to elucidate the mechanism by which fungal leaf endophytes alter disease in their host plants.

“…However, earlier studies on endophytic fungal diversity associated with medicinal plants have documented the endophytic occurrence of Coelomycetes, Basidiomycetes, Hyphomycetes and Ascomycetes (Jin et al 2013). Kurose et al (2012) reported endophytic fungi from the Japanese weed Fallopia japonica that belonged only to Ascomycota.…”

Endophytic fungi are major contributors to fungal diversity and an important component of plant microbiota. Plants growing in biodiversity hotspots and having ethnobotanical utility are often explored for the presence of endophytic fungi with bioactive potential. Western Ghat mountains of India are one of the ten famous biodiversity hotspots in the world. Hence, in the present study, we investigated the diversity of endophytic fungi associated with tissues of Nothapodytes foetida (a tree), Hypericum mysorense (a shrub) and Hypericum japonicum (a herb) collected from forests of Western Ghats with emphasis on diversity of endophytic fungi harbored in different tissues of three plants and their antimicrobial and free radical scavenging activities. A total of 298 isolates belonging to 31 genera were isolated along with dark septate and sterile fungi. All isolates belonged to Dothidiomycetes, Eurotiomycetes and Sordariomycetes of the phylum Ascomycota. Most frequent colonizers were Penicillium, Aspergillus, Fusarium, Gliocladium, Cladosporium, Trichoderma, Colletotrichum, and Pestalotiopsis. Endophytes showed neither any host preference nor any dominance of a single species. Ethyl acetate extracts of 39 endophytic fungi exhibited antimicrobial activity against one or more pathogens, of which the activity of Bionectria ochroleuca NOTL33, Chaetomium globosum HYML55, Alternaria brassicae HYMS01, Aspergillus sp. HYML56 was prominent against most of the pathogens tested. 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) free radicals were effectively quenched by the ethyl acetate extracts of 28 isolates and 34 isolates, respectively. This study is the first of its kind in H. mysorense and H. japonicum, and not only describes the endophytic diversity of these plants but also emphasizes the bioactive potential of endophytic isolates for future use in agricultural, pharmaceutical and industrial applications.
