| 英文摘要 | Porphyra yezoensis Ueda and P. tenera Kjellman are two common commercial seaweeds cultivated in China, but it is difficult to identify them routinely because they are morphologically and systematically very close. The nuclear ribosomal internal transcribed spacer-1 (ITS-1) region of nine selected Porphyra cultivars from China were sequenced and determined. Combined with some ITS-1 data from GenBank, the phylogenetic analysis inferred from the neighbour-joining method indicated that the Porphyra species in this study exhibited clear taxonomic relationships and could be identified clearly to species. Based on the results, the random amplified polymorphic DNA ( RAPD) technique was applied to distinguish 12 Porphyra cultivars, some of which turn out to be different lineages of the same Porphyra species. Eight specific RAPD markers were scored and used to construct a fingerprint that could distinctly identify different Porphyra cultivars. The results suggest that both the rDNA ITS-1 sequence and RAPD markers are useful methods to identify Porphyra cultivars, and may also be valid for phylogenetic and taxonomic studies. |
