“…The leaves showed the second highest H' index value (1.79), and have the same level of diversity index (medium level) as reported in other study (H'=1.97) (Gupta dan Chaturvedi 2017). Similar results were also reported on the endophytic fungi isolated from Piper nigrum in which the root had higher H' value (H'=1.33) than leaf (H'=0.69) and petiole (H'=0.69) (Uzma et al 2016).…”

Endophytic fungi live in healthy tissues of many plants, including in medicinal plant such as Asiatic pennywort (Centella asiatica). These fungi exist in different parts of the plant as symbionts. The study aimed to isolate endophytic fungi from various parts of Asiatic pennywort of Malaysia accession and characterize their nature. Three individual plants of Asiatic pennywort (3 months-old) were obtained from the Sringanis Medicinal Garden in Bogor. The endophytes were isolated on Malt Extract Agar. The community structures of the endophytes were analyzed based on their diversity, colonization, dominance index, and relative frequency of occurrence of the isolated endophytic fungi. A total of 78 isolates have been obtained from three individual plants and clustered into 22 morphotypes consisted of 18 morphotypes of Ascomycota and 4 morphotypes of Basidiomycota divisions. The stolons harbored more endophytes (22.9 %) followed by leaf (16.7 %), root (11.8 %), and petiole (7.6 %). The diversity index was classified as medium category with the highest result (1.91) was found in the root, followed by leaf (1.79), stolon (1.75), and petiole (1.29). The most dominant endophytes were identified as Ceratobasidium sp., Colletotrichum sp, and Fusarium sp. Ceratobasidium sp. has the highest dominance index (0.02). UPGMA cluster analysis grouped the endophytic fungi into distinct clusters based on the plant parts origin. This study implied that stolon was the the most suitable part of Asiatic pennywort for isolating endophytic fungi. Further study is required to examine the role of the endophytic fungi to produce secondary metabolites in Asiatic pennywort.

“…The present study results showed that Aspergillus genus was the most common isolate followed by Eladia "Penicillium related strains (7)" and Cladosporium. Aspergillus, Penicillium, and Cladosporium were also reported among the dominant endophytic isolates obtained in many other studies (15)(16)(17).…”

Fifty-four endophytic fungal species were isolated from 10 medicinal plants growing on different geographical Egyptian habitats; 48 of them were morphologically identified, at least to genus level and all belonged to ascomycetes. Ethanolic extracts of 49 isolates were screened for their antibacterial activities against three Gram-positive and three Gram-negative bacteria; they were also screened for their antifungal activities against Candida albicans and Fusarium solani. Twenty-six isolates showed antibacterial activities at least against one tested bacterial strain and seven isolates showed antibacterial activities against both Gram-negative and-positive bacteria. Moreover, cytotoxicity of these extracts were tested against one normal cell line MRC-5 and another cancer cell line MCF-7 using MTT assay. It was found that a group of seven isolates exerted a reduced toxicity towards the normal cell line, but had a higher toxic effect on the cancer cell line. These isolates represent a promising source for anticancer compounds with low cytotoxicity against the normal cell lines.

“…In contrast, many true phytopathogenic fungi have developed mechanisms to actively cross barriers to the outer structure of plants, cuticles and cell walls of the epidermis. Fungi generally secrete a number of hydrolysis enzymes, including cutaneous, cellulase, pectinase and protease (Uzma et al, 2016).…”

Weeds are a major problem in crop cultivation, either in food crops, horticulture, plantations or forests and cause a decrease in the quality and quantity of production. Weed biocontrol, especially by using plant pathogenic fungi, has received attention but is still lacking in application. The purpose of this study was to determine the potential of Fusarium sp. and Chaetomium sp. as biological control agents against five broad-leaf weeds (Asystasia gangetica L., Ageratum conyzoides L., Synendrella nodiflora (L.) Gaertn., Wedelia trilobata (L.) U.S. Hitchc. and Amaranthus spinosus L.). The variables observed were the incubation period, disease incidence, disease intensity, as well as weed fresh and dry weight. The results of this study showed that the two pathogenic fungi, Fusarium sp. and Chaetomium sp., can cause a more intensive disease in A. conizoides than A. spinosus. A. gangetica, S. nodiflora and W. trilobata; however, the fungi have not been able to inhibit the growth and kill the weeds. Therefore, improvement need to be done by modifying the media to increase the ability of fungi to control weeds.
