Abstract

We conducted a morphological observation and molecular phylogenetic analyses on bladed Bangiales collected from natural populations on Shikinejima Island and Hachijojima Island of the Izu Islands, southern central Japan. The morphological features of the gametophytic blades such as the blade shape, blade margin and reproductive cell divisions were extremely similar to those parameters of Neoporphyra haitanensis, a species cultivated in southern China, and Neoporphyra dentata. However, the blades collected from the two islands were thicker than the blades of N. dentata; this feature was the same as that of N. haitanensis. The chloroplast RUBISCO spacer sequences of present samples were identical to the sequences of N. haitanensis from China. Moreover, phylogenetic positions of three conchocelis strains isolated from the blades on the two islands were examined based on concatenated sequences of the chloroplast rbcL gene and nuclear 18S rRNA. The results showed that the strains were resolved in a clade including N. haitanensis; however, the strains were separated from N. haitanensis in China. Therefore, the bladed Bangiales from the two islands were identified as N. haitanensis. The present study is the first record of N. haitanensis in natural populations in Japan.

日本中南部伊豆列岛岛和八重岛的坛新豚（T.J.Chang&B.F.Zheng）J.Brodie&L.‐E.Yang（Bangiales，Rhodophyta）的首次记录

对日本中南部伊豆群岛石岛和八丈岛自然种群中采集的有叶虎进行了形态观察和分子系统发育分析。配子体叶片的叶片形状、叶缘、生殖细胞分裂等形态特征与中国南方的海棠新叶卟(Neoporphyra haitanensis)和齿状新叶卟(Neoporphyra dentata)极为相似。然而，从两个岛屿采集的叶片比齿齿蕨的叶片厚;这一特征与海棠相同。本研究样品的叶绿体RUBISCO间隔序列与中国海地稻的序列相同。此外，根据叶绿体rbcL基因和细胞核18S rRNA序列的连接，对从两个岛屿叶片中分离的3株螺虫进行了系统发育定位。结果表明，这些菌株在包括海地奈瑟菌在内的一个分支中分离;然而，这些菌株是从中国的海坦乳杆菌中分离出来的。因此，这两个岛屿上的有叶孟加拉虎被鉴定为海地亚种。本研究是首次在日本的自然种群中记录到海坦白蚁。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
