利用AFLP和SSR分析对北海道沿岸及周边地区的日本糖精（saccharina japonicaina）进行了遗传多样性调查。基于AFLP数据的结构分析确定了该物种的两个聚类，尽管发现了一些与邻近群体遗传结构不同的局部群体。即使在每个现有品种中也可以识别出这两个集群。在SSR分析中，所有样本的核苷酸序列的遗传变异位于4个DNA区域（MS10、MS11、MS16和MS29），认为这些区域可以作为检测个体水平inS变异的标记。粳稻。SSR数据的结构分析鉴定出4个聚类。由于这4个不同聚类的地理分布与该物种目前已知的品种并不完全对应，因此有必要对该物种的分布进行重新评估。粳稻。
The genetic diversity ofSaccharina japonicainhabiting the Hokkaido coastline and the surrounding area was investigated by AFLP and SSR analyses. A STRUCTURE analysis based on the AFLP data identified two clusters in the species, although a few local populations with genetic structures different from that of the neighboring populations were detected. The two clusters could be identified even within each current variety. In the SSR analysis, genetic variation in nucleotide sequences in all samples was located in four DNA regions (MS10, MS11, MS16, and MS29), and it is thought that these regions can be used as markers to detect individual-level variation inS. japonica. The STRUCTURE analysis of the SSR data identified four clusters in the species. Since the geographical distribution of these four different clusters does not correspond exactly to the currently recognized varieties in this species, it will be necessary to re-evaluate the distribution of the varieties ofS. japonica.
