ABSTRACT

Endophytic green algae growing in fronds of Grateloupia spp. were examined for infection frequency from their field populations of Jeju, Wando, and Uljin, Korea in August and September 2013. Three endophytes were isolated in laboratory culture from a G. lanceolata thallus collected in Jeju. Unialgal cultures were made from the endophytes, and their morphological characteristics were observed with light microscopy. In addition, a phylogenetic analysis based on chloroplast- encoded elongation factor tufA gene sequences was performed to identify the G. lanceolata endophytes. Three filamentous green endophytic species, Ulvella leptochaete, Blastophysa rhizopus, and Bolbocoleon piliferum were reported for the first time in Korea. General biological information for the three endophytes was also described.

Key words: Blastophysa rhizopus; Bolbocoleon piliferum; endophytic algae; Grateloupia; Ulvella leptochaete
