ABSTRACT

Phylloplane and endophytic fungi are considered as the best source of novel biocompounds of and have a high level of structural diversity on the leaf surfaces. Bioactive complexes produced by these phylloplane and endophytes have publicized gifted prospective towards human health, for which, it is essential to capture and operate this vital microbial resource and make it more helpful for the welfare of manhood. During the present study, isolation and enumeration of Ectophytic (phylloplane) and endophytic fungi were carried out from one medicinal plant, Plectranthus amboinicus Lour. with the host relationship based on the methodology i.e., agar plate method. Overall, 16 phylloplane and endophytic fungal species of 8 genera were isolated from the medicinal plant, Plectranthus amboinicus Lour. In distribution of leaf surface fungi, phylloplane contributed the maximum (70%) followed by the endophytes (30%) in Plectranthus amboinicus plant. In the phylloplane and endophytic fungal population, Aspergillus awamori, Aspergillus flavus, Aspergillus nidulans, Aspergillus niger, Aspergillus terreus, Penicillium oxalicum, Penicillium citrinum, Penicillium chrysogenum, Gray sterile mycelia were the most dominant fungal species in the agar plate method. Fungi isolated from both the upper and sub-surface of leaf were more or less similar to each other. Antimicrobial potential of the leaf surface fungal extracts was very effective against E. coli, Pseudomonas aeruginosa, Shewanella putrefaciens and Candida albicans but Staphylococcus aureus was found to be resistance towards the fungal extracts. The host relation favored and tissue description sign was recognized between the phylloplane and endophytes based on the fungal community dispersal and structure.
