“…Endophytes enhance plant growth by the production of plant hormones such as indole-3-acetic acid (IAA), gibberellins (GAs) and cytokinins (Khan et al 2014). Antimicrobial metabolites like colletotric acid (Zou et al 2000), griseofulvin (Park et al 2005) and glucosidase inhibitor 3S, 4R-(? )-4-hydroxymellein (Rivera-Chavez et al 2015) were reported from endophytic fungi.…”

Only scanty reports are available on endophytic fungal associations in Achyranthes aspera Linn. Hence in this study a total of 504 isolates belonging to ten different species of fungi were isolated from asymptomatic, surface sterilised segments of leaf, stem and root of A. aspera collected from different locations of Kerala, India. Among the isolates ascomycetes were most prevalent. Colonisation rate of fungal endophytes was high in leaf tissue (95%) followed by stem (77.75%) and root segments (33.33%). The most frequent and dominant coloniser of the host plant were Colletotrichum sp., which was isolated from all locations. Scanning electron microscopy demonstrated the presence of hyphae in the intra and intercellular spaces of the plant tissue. Morphological and phylogenetic analyses using internal transcribed spacer (ITS) sequences of nuclear rRNA genes showed that the fungi recovered belonged to the lineages of Sordariomycetes, Dothideomycetes, Eurotiomycetes and Tremellomycetes. A maximum likelihood tree revealed the relationship between the obtained sequence data and the closest sequences retrieved from the GenBank.

“…The highest inhibition was shown by the isolate CgloTIN05 (40.33 %) against P. theae and CgloTIN04 (37.67 %) against C. camelliae. The metabolite, colletotric acid produced by endophytic C. gloeosporioides from Artemisia mongolica which display antimicrobial activity against bacteria as well as the fungus Helminthosporium sativum has been shown [39]. Crude EtOAc extract of endophytic C. gloeosporioides showed strong antifungal activity against the phytopathogenic fungi Cladosporium cladosporioides and Cladosporium sphaerospermum [40].…”

In Vitro Evaluation of Antagonism of Endophytic Colletotrichum gloeosporioides Against Potent Fungal Pathogens of Camellia sinensis

et al. 2014

An endophytic fungus isolated from Camellia sinensis, Assam, Northeastern India was identified as Colletotrichum gloeosporioides on the basis of morphological characteristics and rDNA ITS analysis. This endophytic fungus was evaluated for growth inhibition against tea pathogens Pestalotiopsis theae and Colletotrichum camelliae. One isolate of C. gloeosporioides showed strong antagonistic activity against Pestalotiopsis theae (64 %) and moderate activity against C. camelliae (37 %). Fifty percent cell-free culture filtrate from 5-day-old cultures showed highest antagonistic activity against both the pathogens although the inhibition percent was less as compared to dual culture. In the experiment of volatile compounds none of the isolates of C. gloeosporioides strains showed visible inhibition against P. theae and C. camelliae. The activity of extracellular hydrolytic enzymes chitinase and protease was also high in this culture fluid and measured 10 and 4.3 IU/ll, respectively.

“…Zou found a new antimicrobial metabolite, named colletotric acid, from a liquid culture of C. gloeosporioides, an endophyte found inside the stem of Artemisia mongolica [18]. Further purification and chemical analyses are warranted to elucidate the structure of the antibacterial compound.…”
