| 1 | Morphological observation and rbcL gene sequences studies of two new species,Grateloupia dalianensis H.W.Wang et D.Zhao,sp.nov.and G.yinggehaiensis H.W.Wang et R.X.Luan,sp.nov.(Halymeniaceae,Rhodophyta) from China显示文摘A few species in the genus Grateloupia (Halymeniaceae,Rhodophyta) have been investigated in detail with respect to morphological observations and molecular analyses.In this study,the authors document the vegetative and reproductive structures of two new species of Grateloupia,G.dalianensis H.W.Wang et D.Zhao,sp.nov.and G.yinggehaiensis H.W.Wang et R.X.Luan,sp.nov.They both have the morphological character that carpogonial ampullae and auxiliary cell ampullae are the simple Grateloupia-type.The two species can be distinguished from other species of the genus by their distinctive morphological features respectively.Based on ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) gene sequences,the phylogenetic tree obtained in the study indicated that they are both embedded within the Grateloupia clade.G.dalianensis clusters a subclade with G.asiatica,and G.yinggehaiensis forms a single monophyletic subclade with G.hawaiiana. | ZHAO Dan WANG Hongwei SHENG Yingwen LV Jianzhou LUAN Rixiao | 2012 | Acta Oceanologica Sinica2012，31，2： | 20 |
| 2 | Re-identifying Grateloupia yangjiangensis(Rhodophyta, Halymeniaceae) based on morphological observations, life history and rbcL sequence analyses显示文摘On the basis of morphological observations, life history and molecular phylogeny, Grateloupia yangjiangensis, which is similar to G. filicina, G. orientalis, G. catenata, and G. ramosissima in appearance, was re-examined. The results are as follows:(1) the auxiliary-cell ampullae of G. yangjiangensis were of Grateloupia type, thalli was fleshy and gelatinous in texture, and the erect axes were compressed; the cortex was 0.25–0.30 mm thick, consisting of five to seven outer layers, and there were five inner layers of triangular or stellate cells;(2) there was no filamentous stage in the development of the carpospores;(3) the ribulose-1,5-bisphosphate carboxylase/oxygenase gene(rbcL) sequence of four G. yangjiangensis examined showed that there was no intergeneric divergence among them, and for the phylogenetic tree, four sequences of G. yangjiangensis formed a single monophyletic subclade within the large Grateloupia clade of Halymeniaceae. In conclusion, G. yangjiangensis was a single species within the genus Grateloupia. This research provided criterion for identification and cultivation of G. yangjiangensis. | WANG Hongwei GUO Shaoru ZHANG Xiaoming ZHAO Dan ZHANG Wen LUAN Rixiao | 2014 | Acta Oceanologica Sinica2014，33，4： | 10 |

| 4 | Two new species of Family Prasiolaceae (Prasiolales,Chlorophyta) from China Sea显示文摘Amomg the 30 known species of the algal family Prasiolaceae(Prasiolales,Chlorophyta),nine marine species have been found in marine environments but none in China seas.We reported here two new species Prasiola fangchengensis Luan et Ding sp.nov.and Prasiola volcanica Luan et Ding sp.nov.from subtropical coastal water of southern China. | LUAN Rixiao HUANG Bingxin DING Lanping LUAN Shujun | 2009 | Acta Oceanologica Sinica2009，28，6： | 1 |
