Endophytic Fungi Isolated from the Marine Macroalga Dictyopteris pacifica in Korea

Summary

Researchers in Korea discovered three species of fungi living inside a brown seaweed called Dictyopteris pacifica. These fungi were previously unknown in Korea and were identified using genetic analysis. The fungi have mutualistic relationships with the seaweed and may produce compounds useful for medicines and treating diseases.

Background

Endophytic fungi associated with seaweeds have significant ecological functions and potential as sources of bioactive compounds. Research on endophytic fungi in Korean marine ecosystems remains limited, with few studies examining seaweed-associated endophytes.

Objective

To isolate and identify endophytic fungi from the brown seaweed Dictyopteris pacifica collected from the intertidal zone of Yeongdeok, Korea using morphological examination and molecular phylogenetic analysis.

Results

Three fungal species not previously recorded in Korea were identified: Emericellopsis fuci, Neoarthrinium lithocarpicola, and Periconia chimonanthi. Detailed morphological descriptions and phylogenetic analyses confirmed these identifications with high sequence identity percentages (>99% for most markers).

Conclusion

This study enhances understanding of seaweed-associated endophytic fungal diversity in Korea and highlights D. pacifica as a valuable host for symbiotic endophytic fungi. These fungi show potential as sources of bioactive compounds for pharmaceutical and biotechnological applications.
