摘要
The complete nucleotide sequences of ssu rRNA genes were determined for nine species of Porphyra. Ssu rRNA gene structure was classified into four types by the presence and absence of intron(s). Gene structure even differed within the same species. Exon nucleotide sequences were identical within the same species, but differed among species. Seventeen species of Porphyra were discriminated by comparing the sequences of these diversified regions, using the results of this study and previous studies.
