Abstract
|
|
|
|
Nuclear 18S ribosomal RNA gene (18S rDNA or SSU rDNA) from the Porphyra dentata tissue was amplified and sequenced. Complete 18S rDNA has an 1822 bp exon and a 512 bp intron. The G+C contents of exon and intron were 49% and 55%, respectively. The exon sequence showed 97.1% homology to the GenBank accession number AB013183 of the Japanese P. dentata. The intron region that is inserted in upstream between 568 and 569 showed 52.1% homology to the AB013183.
