Abstract

Members of the brown algal order Asterocladales are characterized by stellate arrangement of its chloroplasts, in which a stellate configuration has a protruding central pyrenoid complex. The order is represented by the genus Asterocladon, which consists of only three species so far. Similar to other small and filamentous seaweeds, studies on Asterocladon remain scant and their diversity poorly understood. To fill this gap, we conducted molecular‐assisted taxonomic studies on Asterocladon based on seven culture isolates collected from Okinawa Prefecture, Japan and Cebu, the Philippines. One culture isolate from the Philippines was revealed to be a new species of Asterocladon based on morpho‐anatomical and molecular analyses using rbcL and psaA genes and is described here as Asterocladon ednae. The other isolates were attributed to A. rhodochortonoides. A. ednae was most closely related to A. rhodochortonoides in morphology and molecular phylogeny but was distinguished from the latter by its elongately ellipsoid plurilocular sporangia. This is the first report of the genus and species A. ednae in the Philippines, further increasing the diversity of seaweeds in the country.

产自菲律宾的星形cladon ednae sp. 11 .(星形cladales, phaophyceae)

褐藻目Asterocladales的成员的特征是其叶绿体的星状排列，其中星状结构具有突出的中央蛋白核复合体。该目以Asterocladon属为代表，迄今为止该属仅由三个物种组成。与其他小型丝状海藻类似，对Asterocladon的研究仍然很少，对其多样性的了解也很少。为了填补这一空白，我们基于从日本冲绳县和菲律宾宿务收集的七个培养分离株，对Asterocladon进行了分子辅助分类研究。根据rbcL和psaA基因的形态解剖和分子分析，一个来自菲律宾的培养分离物被发现是Asterocladon的一个新种，在这里被描述为Asterocladon-ednae。其他分离株均归属于杜鹃花。A.ednae在形态和分子系统发育上与A.rhodochoronoides亲缘关系最为密切，但与后者的区别在于其细长的椭球多室孢子囊。这是菲律宾首次报告A.ednae属和物种，进一步增加了该国海藻的多样性。

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.
