Abstract
Endophytic microorganisms are microbial associates living in various part of host, yet expressing benefits to healthy plants. Existence of species-specific endophytes, endophytic fungi is still poorly studied especially in Zingiberaceae. In this study, we reported several endophytic fungal species isolated from rhizome of Elettaria through isolative efforts and molecular evidence. Host plant, Elettaria sp. was sampled from representative natural area, i.e. Hutan Sibayak which is known as biodiversity spot for Zingiberaceae in North Sumatera. Molecular identification revealed the identity of five isolated fungal strains collected from rhizomes of Elettaria, namely Trichoderma atroviride, Curvularia lunata, Schizophyllum commune, Trichoderma harzianum and Pholiota multicingulata. Phylogenetic tree is constructed based on Neighbor-joining method in a bootstrap test (1000x replication) with outgroup and database retrieved from NCBI GenBank. From our perspective, this is the first report on finding fungal endophytes from rhizomes of Elettaria sp. yet further investigation is needed to evaluate their future bioprospectives.
