초록

The 185 ribosomal RNA gene (185 rDNA) of the marine alga Porphyra sp. 723 (Bangiales, Rhodophyta) was amplified using the polymerase chain reaction and its sequence was analysed. The Porphyra species was a summer strain collected on rocks in upper intertidal zone at Ikidae, Pusan on 23rd July 1999. The fronds were $1{\~}5 cm$ long, monostromatic, and orbicular or ovate shaped, They had spinulate processes at margin of the frond, Comparison of this 185 rDNA sequence with the other Forphyra species indicates that Porphyra sp. 723 has the same 185 rDNA sequence derived from Porphyra suborbiculata (NCBI access number; AB 013180) except one base pair substitution in 2327 base pairs.
