New record of Halymenia malaysiana (Halymeniaceae, Rhodophyta) from Viet Nam, and its genetic diversity in the western Pacific
Abstract Halymenia malaysiana, one of the foliose species of Halymenia was first reported from Malaysia and showed some morphological features that distinguish it from sister species, such as Halymenia dilatata, Halymenia maculata, and Halymenia porphyraeformis. In this study, Halymenia samples were collected from nine locations along the coast of Viet Nam (8°–17°N) in the South China Sea and Gulf of Thailand. Morphological observations indicated that almost all samples were Halymenia malaysiana which was supported by two genetic markers, rbcL and COI-5P. However, the presence of Halymenia dilatata in Viet Nam is still unresolved. Based on rbcL, the common haplotype in Viet Nam was R1 as in Malaysia and three new haplotypes were added to H. malaysiana for Southeast Asia. Genetic differences were evident between the Sunda Shelf (Viet Nam and Malaysia) populations and those in Philippine waters. We suggest that a combination of morphology and molecular data would be useful to accurately assess the species diversity and phylogeography of Halymenia in Viet Nam and Southeast Asia region.
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.
