摘要：

Nucleotide sequences of the nuclear SSU rDNA and ITS1 are presented as a defined genetic marker for Porphyra tenera as a species. Exon nucleotide sequences were identical within all the P. tenera specimens. Intron nucleotide sequences varied between populations. The introns and ITS1 variations are presented as defined genetic markers to establish the Porphyra tenera strains. Wild-collected thalli identified by morphological systematics, from five populations of Porphyra tenera throughout Japan, were discriminated by comparing sequences of the various regions utilizing the results of this and previous studies.
