“…Only a few studies examined the biochemical effects of fungal endophytes on grapes and the resultant wines. These fungal endophytes have the capacity to produce plant secondary metabolites, especially resveratrol, trans-resveratrol and its oligomer, which alter the grape metabolite composition [ 27 – 29 ]. Recent works demonstrated the metabolic impact of endophytes on grape cells [ 30 , 31 ], but no reports examined these issues on vine leaves.…”

Endophytic fungi produce many novel bioactive metabolites that are directly used as drugs or that function as the precursor structures of other chemicals. The metabolic shaping of endophytes on grape cells was reported previously. However, there are no reports on the interactions and metabolic impact of endophyte symbiosis on in vitro vine leaves, which may be examined under well-controlled conditions that are more representative of the natural situation of endophytes within grapevines. The present study used an in vitro leaf method to establish endophyte symbiosis of grapevines and analyze the effects on the metabolic profiles of grape leaves from two different cultivars, 'Rose honey' (RH) and 'Cabernet sauvignon' (CS). The effects of endophytic fungi on the metabolic profiles of grape leaves exhibited host selectivity and fungal strain specificity. Most of the endophytic fungal strains introduced novel metabolites into the two varieties of grape leaves according to the contents of the detected metabolites and composition of metabolites. Strains RH49 and MDR36, with high or moderate symbiosis rates, triggered an increased response in terms of the detected metabolites, and the strains MDR1 and MDR33 suppressed the detected metabolites in CS and RH leaves despite having strong or moderate symbiosis ability. However, the strain RH12 significantly induced the production of novel metabolites in RH leaves due to its high symbiosis ability and suppression of metabolites in CS leaves.

“…aureus produces resveratrol. Resveratrol is a polyphenolic flavonoid and widely used as a therapeutic moiety as well as a pharmacophore for the development of novel drugs because of its various beneficial effects [31]. It has been reported to have beneficial effects in the treatment of neurological diseases like Alzheimer’s, dementia, and Parkinson’s diseases [32,33].…”

Characterization of Three Species of Sordariomycetes Isolated from Freshwater and Soil Samples in Korea

During a survey of fungal diversity in the class Sordariomycetes, 3 fungal strains, CNUFC-KMHY6-1, CNUFC-MSW24-2-11, and CNUFC-GW2S-4 were isolated from soil and freshwater samples, respectively in Korea. The strains were analyzed both morphologically and phylogenetically on the basis of internal transcribed spacer and RNA polymerase II second largest subunit gene sequences. On the basis of their morphology and phylogeny, CNUFC-KMHY6-1, CNUFC-MSW24-2-11, and CNUFC-GW2S-4 isolates were identified as Arcopilus aureus , Memnoniella echinata , and Stachybotrys sansevieriae , respectively. To the best of our knowledge, Ar . aureus and M . echinata have not been previously recorded in Korea, and this is the first report of S . sansevieriae from freshwater niche.

“…The morphological and molecular analyses allowed the identification of the C2J6 strain of Aspergillus niger , showing stable high resveratrol production (Liu et al, 2016). Dwibedi and Saxena (2018) analyzed the resveratrol-producing potential of 53 endophytic fungi from different V. vinifera varieties in different regions in India. The resveratrol-producing isolates were assigned to the following seven genera: Aspergillus , Botryosphaeria , Penicillium , Fusarium , Alternaria , Arcopilus , and Lasiodiplodia .…”

The Role of the Endophytic Microbiome in the Grapevine Response to Environmental Triggers

et al. 2019

Endophytism within Vitis represents a topic of critical relevance due to the multiple standpoints from which it can be approached and considered. From the biological and botanical perspectives, the interaction between microorganisms and perennial woody plants falls within the category of stable relationships from which the plants can benefit in multiple ways. The life cycle of the host ensures persistence in all seasons, repeated chances of contact, and consequent microbiota accumulation over time, leading to potentially high diversity compared with that of herbaceous short-lived plants. Furthermore, grapevines are agriculturally exploited, highly selected germplasms where a profound man-driven footprint has indirectly and unconsciously shaped the inner microbiota through centuries of cultivation and breeding. Moreover, since endophyte metabolism can contribute to that of the plant host and its fruits’ biochemical composition, the nature of grapevine endophytic taxa identities, ecological attitudes, potential toxicity, and clinical relevance are aspects worthy of a thorough investigation. Can endophytic taxa efficiently defend grapevines by acting against pests or confer enough fitness to the plants to endure attacks? What are the underlying mechanisms that translate into this or other advantages in the hosting plant? Can endophytes partially redirect plant metabolism, and to what extent do they act by releasing active products? Is the inner microbial colonization necessary priming for a cascade of actions? Are there defined environmental conditions that can trigger the unleashing of key microbial phenotypes? What is the environmental role in providing the ground biodiversity by which the plant can recruit microsymbionts? How much and by what practices and strategies can these symbioses be managed, applied, and directed to achieve the goal of a better sustainable viticulture? By thoroughly reviewing the available literature in the field and critically examining the data and perspectives, the above issues are discussed.
