Endophytic fungi are those that colonize the living tissues of plants without causing any disease symptoms. As colonisers of different parts and species of plants, they offer protection to the plant against herbivore and insect pest damages while also producing secondary metabolites which can be used in biotechnological processes. The aim of this study was to investigate the diversity of endophytic fungi colonizing the leaves of theAvicenna germinans(Black mangrove),Rhizophora mangle(red mangrove)andLaguncularia racemosa(white mangrove), from Palmyra, Bush Lot Beach and Wellington Park Beach, Corentyne, Berbice, Guyana South America. A total of 303 isolates were obtained from this study. These isolates were classified into 18 species and 9 genera. The 18 species obtained areAspergilluscalidoustus, A. flavus, A. fumigatus, A.luchuensis, A. nidulans, A. niger, A. terreus. Aspergillus spp., Alternaria spp., Candida krusei, Cladosporium spp., Curvurlaria spp., Fusarium spp., Penicillium spp., Penicillium chrysogenum, Penicillium citrinum, Pythopthora spp.,andRhizopus spp.Based on the Shannon Weiner Diversity Index (H’) calculation,Avicenna germinanswas found to have the greatest species diversity followed byRhizophoramangleand thenLagunculariaracemosa. Aspergilluswas found to be the most dominant genus of all isolates withA. nigerandA. flavusbeing the most common species among all three species of mangroves. |
