| 1 | Reproduction Diversity of Enteromorpha prolifera显示文摘Enteromorpha prolifera(Muell.) J.Agardh(Chlorophyta,Ulvophyceae),which is distributed widely in the inter-tidal zone of the ocean,is one of the most common fouling green algae.However,the present understandings of the life history of E.prolifera have been insufficient to explain their seasonal abundances.Thus it is essential to investigate how many reproductive strategies are likely to contribute to the successful colonization and flourishing of the green alga.In the present study the reproduction diversity of E.prolifera was observed and studied systematically by culturing chopped tissues.Our results showed that there are in total seven pathways of reproduction for E.prolifera including sexual,asexual and vegetative reproduction.It was indicated that the variety of the reproductive ways and the large quantity of reproductive cells produced and released during the reproductive season are the two key factors that facilitate colonization of E.prolifera.The reproduction of the alga E.prolifera mainly depends on asexual methods.The results presented here contribute to increasing our understanding about how the opportunistic macroalgae successfully maintain colonization and excessive growth. | Apeng Lin Songdong Shen Jianwei Wang Binlun Yan | 2008 | Journal of Integrative Plant Biology2008，50，5： | 46 |
| 2 | MiR-122 in hepatic function and liver diseases显示文摘As the most abundant liver-specific microRNA,mi-croRNA-122(miR-122)is involved in various physio-logical processes in hepatic function as well as in liver pathology.There is now compelling evidence that miR-122,as a regulator of gene networks and pathways in hepatocytes,plays a central role in diverse aspects of hepatic function and in the progress of liver diseases.This liver-enriched transcription factors-regulated miRNA promotes differentiation of hepatocytes and regulates lipid metabolism.With regard to liver diseases,miR-122 was shown to stimulate hepatitis C virus(HCV)replication through a unique and unusual interaction with two binding sites in the 5′-UTR of HCV genome to mediate the stability of the viral RNA,whereas inhibit the expression and replication of hepatitis B virus(HBV)by a miR-122-cylin G1/p53-HBV enhancer regulatory pathway.In addition,miR-122 acts as a suppressor of cell prolif-eration and malignant transformation of hepatocytes with remarkable tumor inhibition activity.Notably,a clinical trial targeting miR-122 with the anti-miR-122 oli-gonucleotides miravirsen,the first miRNA targeted drug,has been initiated for treatment of HCV infection.With further understanding of the comprehensive roles of miR-122 in hepatic functions and the mechanisms in-volved in miR-122 down-regulation in chronic hepatitis or hepatocellular carcinoma,miR-122 appears to be a promising candidate for effective therapeutic ap-proaches against tumor and infectious diseases. | Jun Hu Yaxing Xu Junli Hao Saifeng Wang Changfei Li Songdong Meng | 2012 | Protein & Cell2012，3，5： | 22 |
| 3 | Comparison of Chlorophyll and Photosynthesis Parameters of Floating and Attached Ulva prolifera显示文摘In mid-May 2008 a serious green tide caused mainly by floating Ulva prolifera(Mller) J.Agardh(Chlorophyta,Ulvales) thalli struck the coastal area of Qingdao,China.To understand the present physiological conditions of the floating alga,in this work both laboratory and field investigations were conducted on the floating U.prolifera thalli in comparison with the attached U.prolifera thalli collected from the area.The floating thalli of three distinctively different colors and attached thalli at three different stages of sporangium formation process were characterized under a microscope,while their photosynthetic parameters were determined with chlorophyll fluorescence technology.On the other hand,the sporangium formation status of the floating U.prolifera thalli was surveyed both in the laboratory and in the field.Comparisons showed that both of the paired morphological characteristics and the paired physiological parameters of the floating and attached U.prolifera thalli were consistent.Furthermore,some spores were confirmed in the field and some motile particles were found within the floating thalli.These results suggest that the floating U.prolifera thalli with different colors could be at different stages of sporangium formation.However,our results also showed that the floating alga thalli have only a limited reproductive potential.This might limit the duration and the further geographic expansion of the green algal bloom. | Apeng Lin Songdong Shen Guangce Wang Qianqian Yi Hongjin Qiao Jianfeng Niu Guanghua Pan | 2011 | Journal of Integrative Plant Biology2011，53，1： | 20 |

| 7 | A New Molecular Label Applied to the Study of the Yellow Sea Green Tide显示文摘From 2007 to 2017,large-scale green tides occurred every year in the Yellow Sea of China,and Ulva prolifera was the main species leading to the green tide.In this study,we used the Polymerase chain reaction and 3'Rapid-amplification of c DNA ends technique to amplify the nr DNA-LSU and IGS sequences in U.prolifera and one species of Blidingia.These techniques showed 3259 bp of nrD NA-LSU and 3388 bp of IGS in U.prolifera and 3282 bp nr DNA-LSU and 3059 bp IGS in Blidingia sp.At the same time,tandem repeats,short dyads,palindromic and multiple simple repeat sequences in the IGS sequence were found by analyzing the structure of the IGS sequence in U.prolifera and Blidingia sp.G+C contents of the IGS sequence in U.prolifera and Blidingia sp.were 52.42% and 53.09%,respectively.We divided the U.prolifera into two types according to the morphological characteristics.Although the specimens of U.prolifera from the Qingdao coastal area,Jiangsu coastal area and the Yellow Sea have different morphologies,their ITS and IGS sequences are almost identical.Therefore,the main species of the green tides in the Qingdao coastal area,Jiangsu coastal area and the Yellow Sea are the same and have the same origin. | SHEN Weijie HE Yuan SHEN Songdong | 2019 | Journal of Ocean University of China2019，18，6： | 4 |
| 8 | Isolated Cells of Porphyra yezoensis Cultured on Solid Medium显示文摘Vegetative cells of Porphyra yezoensis are isolated with sea snail enzyme and cultured on the solidified agar medium. The results of experiments show that the isolated cells can survive,divide and regenerate well on the medium solidified with agar. The first division on the solid medium starts after 7 days' culture, 4 days later than the liquid culture. The survival rate of isolated cells is 71.3% on the solid medium, lower than the 86.2% of that in seawater.Thalli, thalloids,conchocelis, spermatangia and multicellular masses are developed on the solid/medium in the first month, slowly but normally. Spermatangia sacs disappear within 4 weeks. Without adding nutrient liquid onto the surface of solid medium or injecting seawater under the agar layer in order to keep moisture, the thalli and cell groups release monospores to form new thalli instead of enlarging their areas after 5 weeks' culturing. Some monospores regenerate new thalli. Other monospores lose their pigments and minimize their volume and divide quickly to form light pink calli. After 16 weeks, numerous calli can be seen on the solid medium and after 24 weeks' culturing, almost only calli and conchocelis can be seen. If the calli are immersed in seawater, the monospores are released and may develop into young thallus. | Shen Songdong(沈颂东) Dai Jixun(戴继勋) | 2001 | Marine Science Bulletin2001，3，1： | 4 |
| 9 | A ^(13)CO isotopic study on the CO promotion effect in methane dehydroaromatization reaction over a Mo/HMCM-49 catalyst显示文摘The promotion effect of CO in methane dehydroaromatization was investigated using 13CO probe molecules. By alternative injection of 13CO to the methane feed,the distribution of 13CxC6-xH6(x=0-3)products changed significantly,confirming the participation of13CO in the reaction network.The addition of 13CO did not change the conversion of CH4 but improved slightly the durability of the methane dehydroaromatization(MDA)reaction,which might be caused by the interaction of the dissociated oxygen species and the deposited carbon species.The ratio of 13CxC6-xH6(x=0-3)varied with the time on stream,which was determined by the competitive reactions of methane decomposition and 13CO dissociation. | Songdong Yao, Changyong Sun, Juan Li, Xiumin Huang, Wenjie Shen State Key Laboratory of Catalysis, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116023, Liaoning, China | 2010 | Journal of Natural Gas Chemistry2010，19，1： | 2 |
