The medicinal plants Centella asiatica, Curcuma xanthorrhiza, Guazuma ulmifolia, and Hydrocotyle verticillata are widely used  in Indonesian traditional medicine, but little is known about their associated endophytic fungi. This research aimed to study the diversity of endophytic fungi derived from functional parts of these plants and to evaluate their potential as antifungal agents against the plant pathogenic fungus Fusarium oxysporum. A total of 17 isolates of endophytic fungi were obtained: nine from leaves of G. ulmifolia, three each from leaves of C. asiatica and H. verticillata, and two from rhizomes of C. xanthorrhiza. The genus Colletotrichum was found in all plants studied, but each plant was associated with different species. Colletotrichum aeschynomenes was associated with C. xanthorrhiza, C. siamense was associated with C. asiatica, and C. tropicale was associated with G. ulmifolia and H. verticillata. The species Curvularia affinis, Diaporthe tectonae, Lasiodiplodia mahajangana, Parengyodontium album, Talaromyces trachyspermus, and Speiropsis pedatospora were found only in G. ulmifolia; while Didymella coffeae-arabicae and Muyocopron laterale were found only in H. verticillata. The endophytic fungi showed inhibition activity against F. oxysporum with inhibition values of 6.0-78.9%, T. trachyspermus JBd10 and C. affinis JBd14 gave the highest inhibition activity.

Endophytic Actinobacteria

Endophytic bacteria are known to reside within host plant tissue without giving a harmfull effect. The endophytes may play an important role, as they may produce similar bioactive compounds as produced by the host plant. Various medicinal plants have long been used to cure diseases. Traditionally, leaves extract of Guazuma ulmifolia, Psidium guajava, or the rhizome of Curcuma xanthorrhiza can be used to treat disease, e.g. hyperlipidemic. The mechanism can be through lipase activity, where the lipase catalyzes the hydrolysis of triacylglycerol to fatty acids and acylglycerol. The objective of this research was to assess potency of endophytic bacteria as anti-hyperlipidemic compounds producer through their lipase activity. Sixty nine endophytic bacteria which comprised of 22, 27 and 20 isolates were isolated from the leaves of G. ulmifolia, P. guajava, and the rhizome of C. xanthorrhiza, respectively. Eight out of the 69 isolates showed lipase activity, and the two selected isolates, i.e. DPG 3(2) and AJB 4(4) were considered as good lipase producers. The highest specific lipase activity of DPG 3(2) isolate was observed for 0.874 units per mg at 38 h, whereas AJB 4(4) isolates had the specific lipase activity at 1.139 units per mg after 72 h observation. These data indicate that the two selected isolates have the potency as antihyperlipidemic compounds producer through their lipase activity.

Biodiversitas 18: 1377-1384. Fusarium oxysporum is a soil borne pathogenic fungus that causes wilt disease in members of the family Solanaceae including the eggplant (Solanum melongena L.). One approach to resolving the problem of wilt disease in eggplant is to find endophytic microbes with antagonistic activity against F. oxysporum. The study reported here aimed to isolate such endophytic fungal antagonists from growing eggplants, to determine their antagonistic mechanisms, and to identify them. Samples of pathogenic fungi from diseased plants, assumed to be F. oxysporum, were obtained from the Laboratory of Plant Pests and Diseases of the Faculty of Agriculture, Universitas Sebelas Maret Surakarta. These were used to evaluate the antagonistic potential of endophytic fungi obtained from healthy eggplants in Dawung Village, Matesih, Karanganyar, Central Java. Specimens of various plant parts were collected from the healthy eggplants. The surfaces of these samples were sterilized for four minutes to remove contaminants, and then crushed excisions were cultured on a potato dextrose agar (PDA) medium. Antagonistic tests between endophytic and pathogenic fungi used the agar plug diffusion technique. Identification of fungi isolates was carried out on the basis of morphological characteristics. Six endophytic fungi isolated had antagonist activity against F. oxysporum. The antagonistic mechanism of FEB1, FEB2, FEB5 and FED1 was competition; FED2 was antibiosis, and FED3 was parasitism. Based on their morphological characteristics, FEB2, FEB5 and FED3 were identified as Helicomyces spp.; FEB1 was a Rhizopus sp.; FED1 was a Mucor sp.; and FED2 was a species of Penicillium.

Objectives. To explore the effective and safe medicines for treating diabetes. Methods. Hydroalcoholic extracts of 130 medicinal plants belonging to 66 families were evaluated using porcine pancreatic lipase (PPL) inhibition and glucose uptake methods together with a literature review. Results. The extracts of 22 species showed the PPL inhibition activity; 18 extracts of 15 species stimulated glucose uptake in 3T3-L1 adipocytes. Among them, Mansonia gagei J.R. Drumm., Mesua ferrea L., and Centella asiatica (L.) Urb. exhibited both activities. The extracts of Caladium lindenii (André) Madison rhizomes and Azadirachta indica A. Juss. leaves presented the utmost lipase inhibitory activity with IC50 of 6.86 ± 0.25 and 11.46 ± 0.06 μg/mL, respectively. The extracts of Coptis teeta Wall. rhizomes and Croton tiglium L. seeds stimulated the maximum glucose uptake. Ten species are reported to have antidiabetic activity for the first time. Flavonoids and triterpenoids are the dominant antidiabetic compounds in selected medicinal plants from Myanmar. Conclusions. P. zeylanica, L. cubeba, H. crenulate, M. gagei, C. teeta, and M. ferrea are worthy to advance further study according to their strong antidiabetic activities and limited research on effects in in vivo animal studies, unclear chemical constitutes, and safety.

Abstract. Radiastuti N, Bahalwan HA, Susilowati DN. 2019. Phylogenetic study of endophytic fungi associated with Centella asiatica from Bengkulu and Malaysian accessions based on the ITS rDNA sequence. Biodiversitas 20:  1248-1258. Centella asiatica is one of the medicinal plants which is known to be symbiotic with various endophytic fungi. The purpose of this research was to determine diversity of culturable fungal endophyte from C. asiatica. Identification was conducted using molecular phylogenetic analysis based on the ITS rDNA sequence. The result showed that obtained 145 isolates endophytic fungi (from stolons, leaves, roots, petioles) were grouped into 18 morphotaxa (Bengkulu) and 23 morphotaxa (Malaysian). The fungal endophytic were identified as Aspergillus austroafricanus, Aspergillus oryzae, Acrocalymma vagum, Ceratobasidium cornigerum, Ceratobasidium sp., Chaetomium globosum, Colletotrichum karstii, C. gigasporium, C. tabaci, Colletotrichum siamense, Eutypella sp., Fusarium solani, F. oxysporum, F. falciforme, F. keratoplasticum, F. striatum, Fusarium sp., Penicillium capsulatum, Phoma multirostrata, Perenniporia tephropora, Perenniporia sp., Phanerochaete chrysosporium, Phanerochaete stereoides, Phyllosticta capitalensis, Phomopsis asparagi, Peroneutypa scoparia, Phialemoniopsis sp., Mycochaetophora gentinae, Talaromyces sp., Earliella scabrosa, and Trichaptum sp. based on molecular phylogenetic analysis. Fusarium (Nectriaceae) were the most found of fungal endophytes in both C. asiatica Bengkulu and Malaysian accession. The majority strain are including Ascomycetes and Basidiomycetes. The identification of endophytic fungi from medicinal plants is needed as a preliminary study to determine the potential of endophytic fungi producing bioactive compounds.

AbstractPrimers specific for the hypothetical forma specialis of Fusarium oxysporum were designed to amplify DNA from this pathogenic fungus that infects plants including lilies. The F. oxysporum sequence between the transposal elements han and hop was used for primer design. Three primer pairs designed from this region were confirmed as specific for 24 isolates of F. oxysporum pathogenic to lilies, except for one pathogenic isolates as extraordinary. No amplification was observed from F. oxysporum non-pathogenic to lily, from 12 forma specialis, and 14 fungi and oomycetes concerned with Liliaceae plants. We propose that specific primers designed from this region will be useful to detect isolates of F. oxysporum that are pathogenic to lilies.

Endophytic fungi are widely present in internal plant tissues and provide different benefits to their host. Medicinal plants have unexplored diversity of functional fungal association; therefore, this study aimed to isolate endophytic fungi associated with leaves of medicinal plants Ephedra pachyclada and evaluate their plant growth-promoting properties. Fifteen isolated fungal endophytes belonging to Ascomycota, with three different genera, Penicillium, Alternaria, and Aspergillus, were obtained from healthy leaves of E. pachyclada. These fungal endophytes have varied antimicrobial activity against human pathogenic microbes and produce ammonia and indole acetic acid (IAA), in addition to their enzymatic activity. The results showed that Penicillium commune EP-5 had a maximum IAA productivity of 192.1 ± 4.04 µg mL−1 in the presence of 5 µg mL−1 tryptophan. The fungal isolates of Penicillium crustosum EP-2, Penicillium chrysogenum EP-3, and Aspergillus flavus EP-14 exhibited variable efficiency for solubilizing phosphate salts. Five representative fungal endophytes of Penicillium crustosum EP-2, Penicillium commune EP-5, Penicillium caseifulvum EP-11, Alternaria tenuissima EP-13, and Aspergillus flavus EP-14 and their consortium were selected and applied as bioinoculant to maize plants. The results showed that Penicillium commune EP-5 increased root lengths from 15.8 ± 0.8 to 22.1 ± 0.6. Moreover, the vegetative growth features of inoculated maize plants improved more than the uninoculated ones.
