The Fungal Diversity Laboratory aims to isolate, identify, and classify fungi associated with plants (fungal endophytes) and to establish a culture collection of these fungi. Currently, the focus is on fungal endophytes associated with plants with documented medicinal uses and plants with characterized bioactive phytochemical profiles. Many endophytic fungi synthesize a variety of bioactive compounds that hold immense potential for medical, agricultural, and industrial applications. A necessary first step to the exploration of these potential bioactive compound producers is their isolation from their respective plant hosts and their subsequent identification. Our study will provide baseline information on the diversity of endophytic fungi associated with Philippine plants. This will lay the groundwork for further investigation on potential bioactive metabolites produced by these fungal endophytes, which we intend to carry out in the future. Our research is currently being supported by the Natural Sciences Research Institute.
