| 1 | Genetic basis and breeding application of clonal diversity and dual reproduction modes in polyploid Carassius auratus gibelio显示文摘A unisexual species is generally associated with polyploidy, and reproduced by a unisexual reproduction mode, such as gyno- genesis, hybridogenesis or parthenogenesis. Compared with other unisexual and polyploid species, gibel carp (Carassius au- ratus gibelio) has a higher ploidy level of hexaploid. It has undergone several successive rounds of genome polyploidy, and experienced an additional, more recent genome duplication event. More significantly, the dual reproduction modes, including gynogenesis and sexual reproduction, have been demonstrated to coexist in the polyploid gibel carp. This article reviews the genetic basis concerning polyploidy origin, clonal diversity and dual reproduction modes, and outlines the progress in new va- riety breeding and gene identification involved in the reproduction and early development. The data suggests that gibel carp are under an evolutionary trajectory of diploidization. As a novel evolutionary developmental (Evo-Devo) biology model, this work highlights future perspectives about the functional divergence of duplicated genes and the sexual origin of vertebrate animals. | GUI JianFang* & ZHOU Li State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，4： | 62 |
| 2 | Integration mechanisms of transgenes and population fitness of GH transgenic fish显示文摘It has been more than 20 years since the first batch of transgenic fish was produced. Five stable germ-line transmitted growth hormone (GH) transgenic fish lines have been generated. This paper reviews the mechanisms of integration and gene targeting of the transgene, as well as the viability, reproduction and transgenic approaches for the reproductive containment of GH-transgenic fish. Further, we propose that it should be necessary to do the following studies, in particularly, of the breeding of transgenic fish: to assess the fitness of transgenic fish in an aqueous environment with a large space and a complex structure; and to develop a controllable on-off strategy of reproduction in transgenic fish. | HU Wei & ZHU ZuoYan* State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，4： | 27 |
| 3 | Genetic analysis of 'all-fish' growth hormone gene transferred carp (Cyprinus carpio L.) and its F_1 generation显示文摘Recornbinant 'all-fish' growth hormone gene (GH) was microinjected into the fertilized eggs of carp. A comparison between the growth traits of transgenics and non-transgenics was carried out, and the transgenic individuals with significant 'fast-growing' effect were successfully gained. A comparison on the reproductivities was also given out between the transgenics and their non-transgenic siblings, and showed that the reproductive capacity of transgenics was substantially equivalent to those of the non-transgenics. On the other hand, the genetic separation and the characteristic distribution of the FI generation were genetically analyzed, which gave solid evidence for the hypothesis that 2-3 chromosomes are integrated with trans-gene. In addition, the distinct biological effects for multi-site-integrated transgenes were further discussed. The present study opens a door for the breeding of 'fast-growing' transgenic fish. | WANG Yaping, HU Wei, WU Gang,SUN Yonghua, CHEN Shangping, ZHANG Fuying,ZHU Zuoyan, FENG Jianxin & ZHANG Xirui1.

| 4 | Screen for stage-specific expression genes between tail bud stage and heartbeat beginning stage in embryogenesis of gynogenetic silver crucian carp显示文摘A systemic study was initiated to identify stage-specific expression genes in fish embryogenesis by using suppression subtractive hybridization (SSH) technique. In this study, we presented a preliminary result on screen for stage-specific expression genes between tail bud stage (TBS) and heartbeat beginning stage (HBS) in gynogenetic silver crucian carp (Carassius auratus gibelio). Two SSH plasmid libraries specific for TBS embryos and HBS embryos were constructed, and stage-specific expression genes were screened between the two stages. 1963 TBS positive clones and 2466 HBS positive clones were sampled to PCR amplification, and 1373 TBS and 1809 HBS PCR positive clones were selected to carry out dot blots. 169TBS dot blot positive clones and 272 HBS dot blot positive clones were sequenced. Searching GenBank by using these nucleotide sequences indicated that most of the TBS dot blot positive clones could not be found homologous sequences in the database, while known genes were mainly detected from HBS dot blot positive clones. Of the 79 known genes, 20 were enzymes or kinases involved in important metabolism of embryonic development. Moreover, specific expressions of partial genes were further confirmed by virtual northern blots. This study is the first step for making a large attempt to study temporal and spatial control f gene expression in the gynogenetic fish embryogenesis. | YAO HUA SHI, JUN LIU, JIAN HONG XIA, JIAN FANG GUIState Key laboratory of Freshwater Ecology and Biotechnology, Wuhan Center for Developmental Biology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2002 | Cell Research2002，12，2： | 17 |
| 5 | Embryonic and genetic manipulation in fish显示文摘Fishes, the biggest and most diverse community in vertebrates are good experimental models for studies of cell and developmental biology by many favorable characteristics. Nuclear transplantation in fish has been thoroughly studied in China since 1960s. Fish nuclei of embryonic cells from different genera were transplanted into enucleated eggs generating nucleo-cytoplasmic hybrids of adults. Most importantly, nuclei of cultured goldfish kidney cells had been reprogrammed in enucleated eggs to support embryogenesis and ontogenesis of a fertile fish. This was the first case of cloned fish with somatic cells. Based on the technique of microinjection, recombinant MThGH gene has been transferred into fish eggs and the first batch of transgenic fish were Produced in 1984. The behavior of foreign gene was characterized and the onset of the foreign gene replication occurred between the blastula to gastrula stages and random integration mainly occurred at later stages of embryogenesis. This eventually led to the transgenic mosaicism. The MThGH-transferred common carp enhanced growth rate by 2-4 times in the founder juveniles and doubled the body weight in the adults. The transgenic common carp were more efficient in utilizing dietary protein than the controls. An 'all-fish' gene construct CAgcGH has been made by splicing the common carp β-actin gene (CA) promoter onto the grass carp growth hormone gene (goGH) coding sequence. The CAgcGH-transferred Yellow River Carp have also shown significantly fast-growth trait. Combination of techniques of fish cell culture, gene transformation with cultured cells and nuclear transplantation should be able to generate ho- mogeneous strain of valuable transgenic fish to fulfil human requirement in 21st | ZHU ZUO YAN YONG HUA SUN (State Key Laboratory of Freshwater Ecology and Biotechnology, Institute Of Hydrobiology, Chinese Academy of Sciences, Luojiashan, Wuhan 430072, China) | 2000 | Cell Research2000，10，1： | 15 |
| 6 | Characteristics of the microbial communities in the integrated vertical-flow constructed wetlands显示文摘Microorganisms play an important role in removing pollutants from constructed wetlands.We investigated the microbial characteristics in a novel integrated vertical-flow constructed wetland(IVCW) ,which has been in operation in Wuhan,China since 1998.We used phospholipid fatty acid(PLFA) and amoA gene to analyze the structure and diversity of the microbial community within the IVCW.PLFA results suggested that the amount of bacterial PLFA was significantly higher than that of fungal PLFA,but the total microbial biomass represented by PLFA index was low in the system.Microbial spatial distribution showed significantly higher bacterial(both G+and G-) and fungal biomass in the surface than in the subsurface layers.The ratios of monounsaturated to branched PLFA demonstrated that an anaerobic layer sandwiched by two aerobic layers existed in the IVCW,consistent with the redox potential results.Analysis of the amoA revealed the presence of Nitrosomonas-like sequences in the surface substrate of the downflow chamber and apparent diversities of ammonia-oxidizing bacteria in the system.These results suggest that microorganisms,despite their relatively low biomass,have inhabited the IVCW,and the results will offer some valuable information on microbe to system designers and managers. | ZHOU Qiaohong,HE Feng,Zhang Liping,WANG Yanfen,WU Zhenbin State Key Laboratory of Freshwater Ecology and Biotechnology,Institute of Hydrobiology,Chinese Academy of Sciences,Wuhan 430072,China Department of Biology and Chemistry,City University of Hong Kong | 2009 | Journal of Environmental Sciences2009，21，9： | 14 |
| 7 | Fish germ cells显示文摘Fish, like many other animals, have two major cell lineages, namely the germline and soma. The germ-soma separation is one of the earliest events of embryonic development. Germ cells can be specifically labeled and isolated for culture and transplan-tation, providing tools for reproduction of endangered species in close relatives, such as surrogate production of trout in salmon. Haploid cell cultures, such as medaka haploid embryonic stem cells have recently been obtained, which are capable of mimicking sperm to produce fertile offspring, upon nuclear being directly transferred into normal eggs. Such fish originated from a mosaic oocyte that had a haploid meiotic nucleus and a transplanted haploid mitotic cell culture nucleus. The first semi-cloned fish is Holly. Here we review the current status and future directions of understanding and manipulating fish germ cells in basic research and reproductive technology. | XU HongYan1, LI MingYou1, GUI JianFang2 & HONG YunHan1,2 1Department of Biological Sciences, National University of Singapore, Singapore 119260, Singapore 2 State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，4： | 12 |
| 8 | Medaka fish stem cells and their applications显示文摘Stem cells are present in developing embryos and adult tissues of multicellular organisms. Owing to their unique features, stem cells provide excellent opportunities for experimental analyses of basic developmental processes such as pluripotency control and cell fate decision and for regenerative medicine by stem cell-based therapy. Stem cell cultures have been best studied in 3 vertebrate organisms. These are the mouse, human and a small laboratory fish called medaka. Specifically, medaka has given rise to the first embryonic stem (ES) cells besides the mouse, the first adult testis-derived male stem cells spermatogonia capable of test-tube sperm production, and most recently, even haploid ES cells capable of producing Holly, a semi-cloned fertile female medaka from a mosaic oocyte created by microinjecting a haploid ES cell nucleus directly into a normal oocyte. These breakthroughs make medaka a favoring vertebrate model for stem cell research, the topic of this review. | YI MeiSheng1, HONG Ni1, LI ZhenDong1, YAN Yan1,2, WANG DanKe1, ZHAO HaoBin1,3 & HONG YunHan1,4* 1Department of Biological Sciences, National University of Singapore, 10 Kent Ridge Crescent, Singapore 119260, Singapore 2Division of Bioengineering, School of Chemical and Biomedical Engineering, Nanyang Technological University, Singapore 637457, Singapore 3Hubei Key Laboratory of Genetic Regulation and Integrative Biology, School of Life Sciences, Huazhong Normal University, Wuhan 430079, China 4State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，4： | 10 |
| 9 | Effects of sand burial on biomass, chlorophyll fluores-cence and extracellular polysaccharides of man-made cyanobacterial crusts under experimental conditions显示文摘Soil cyanobacterial crusts occur throughout the world, especially in the semiarid and arid regions. It always encounters sand burial, which is an important feature of mobile sand dunes. A greenhouse study was conducted to determine the effects of sand burial on biomass, chlorophyll fluorescence and extracellular polysaccharides of man-made cyanobacterial crusts in six periods of time (0, 5, 10, 15, 20 and 30 d after burying) and at five depths (0, 0.2, 0.5, 1 and 2cm). The results indicated that with the increase of the burial time and burial depth extracellular polysaccharides content and Fv/Fm decreased correspondingly and there were no significant differences between 20 and 30 burial days under dif-ferent burial depths. The degradation of chlorophyll a content appeared only at 20 and 30 burial days and there was also no significant difference between them under different burial depths. It was also observed a simultaneous decrease of the values of the Fv/Fm and the content of extracellular poly-saccharides happened in the crusted cyanobacterium Microcoleus vaginatus Gom. It may suggest that there exists a relationship between extracellular polysaccharides and recovery of the activity of pho-tosystem II (PS II) after rehydration. | WANG WeiBo1,2, YANG CuiYun1,2, TANG DongShan1,2, LI DunHai1, LIU YongDing1& HU ChunXiang1 1 State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China 2 Graduate University of Chinese Academy of Sciences, Beijing 100039, China | 2007 | Science China(Life Sciences)2007，50，4： | 9 |
| 10 | Comparative studies on in vitro sperm decondensation and pronucleus formation in egg extracts between gynogenetic and bisexual fish显示文摘A cell-free system based upon the egg extracts from gynogenetic gibel carp (Carassius auratus gibelio)or bisexual red common carp (Cyprinus carpio red variety) was developed to investigate developmentalbehaviors of the demembranated sperm nuclei. Both red common carp and gibel carp sperm nuclei coulddecondense fully and form pronuclei in the red common carp egg extracts. Gibel carp sperm nuclei couldalso decondense fully and form pronuclei in the gibel carp egg extracts, but red common carp sperm nucleicould not decondense sufficiently in the same extracts. The significant differences of morphological changeswere further confirmed by ultrastructural observation of transmission electron microscopy. The data furtheroffer cytological evidence for gonochoristic reproduction in the gynogenetically reproducing gibel carp. Inaddition, the sperm nuclei in vitro decondensation is dependent on the pH in the extracts, and the decon-densed efficiency is optimal at pH 7. However, no DNA replication was observed in the two kinds of eggextracts during the incubation period of the sperm nuclei. It is suggested that the egg extracts preparedfrom the gynogenetic gibel carp should be a valid in vitro system for studying molecular mechanism ongynogenesis and reproduction mode diversity in fish. | CHANG JIAN LI,JIAN FANG GUIState.

| 11 | PCR-RFLP analysis of mitochondrial DNA ND5/6 region among 3 subspecies of common carp (Cyprinus carpio L.)and its application to genetic discrimination of subspecies显示文摘Mitochondrial DNA ND5/6 region was studied by PCR-RFLP analysis among ten representative strains belonging to three subspecies (Cyprinus carpio carpio, Cypri-nus carpio haematopterus and Cyprinus carpio rubrofuscus) of common carp (Cyprinus carpio L.). A total of 2.4 kb frag-ment was amplified and subjected to restriction endonucle-ase analysis with nine restriction endonucleases subsequently.The results indicated that each subspecies owned one hyplo-type and four restriction enzymes (DdeⅠ, HaeⅢ, TaqⅠand MboⅠ) produced diagnostic restriction sites which could be used for discriminating the three subspecies and as molecu-lar genetic markers for assistant selective breeding of com-mon carp. | ZHOU Jianfeng, WANG Zhongwei, YE Yuzhen & WU Qingjiang State Key Laboratory of Freshwater Ecology and Biotechnology, Insti-tute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China Correspondence should be addressed to Wu Qingjiang (e-mail: qjwu@ihb.ac.cn) | 2003 | Chinese Science Bulletin2003，48，5： | 5 |
| 12 | Non-rainfall water sources in the topsoil and their changes during formation of man-made algal crusts at the eastern edge of Qubqi Desert,Inner Mongolia显示文摘In arid and semiarid areas,water uptake (non-rainfall water) serves as an important water source for plants,biological soil crusts,insects and small animals.In this study,a measurement program was undertaken to investigate water uptake and its changes during formation of man-made algal crusts in the Qubqi Desert.In the study region,water uptake from the atmosphere accounted for 25.07%-39.83% of the total water uptake,and was mainly taken up by a water vapor adsorption mechanism;the proportion of water uptake from the soil substrate was much higher (60.17%-74.93%).The formation of crusts promoted water uptake,but the increased uptake did not occur immediately after inoculation or crusts formation.The water taken up from the atmosphere increased significantly from day 15 after inoculation,and the soil water content was markedly enhanced from day 20 after inoculation.It is considered that the growth of algal filaments and their secretions were the main factors increasing the amount of water uptake and water content in the crusts,and these variables increased even during dry periods when some algae are likely to have died. | LAN ShuBin1,2,HU ChunXiang1*,RAO BenQiang1,2,WU Li1,2,ZHANG DeLu1,2 & LIU YongDing1 1State Key Laboratory of Freshwater Ecology and Biotechnology,Institute of Hydrobiology,Chinese Academy of Sciences,Wuhan 430072,China 2Graduate University of Chinese Academy of Sciences,Beijing 100039,China | 2010 | Science China(Life Sciences)2010，53，9： | 5 |
| 13 | Comparative investigation on spindle behavior and MPF activity changes during oocyte maturation between gynogenetic and amphimictic crucian carp显示文摘The spindle behavior and MPF activity changes in the progression of oocyte maturation were investigated and compared with cytological observation and kinase assay between gynogenetic silver crucian carp and amphimictic colored crucian carp. MPF activity was measured by using histone H1 as phosphorylation substrate. There were two similar oscillatory MPF kinase activity changes during oocyte maturation in two kinds of fishes with different reproductive modes, but there existed some subtle difference between them. The subtle difference was that the first peak of MPF kinase activity was kept to a longerlasting time in the gynogenetic silver crucian carp than in the amphimictic colored crucian carp. It was suggested that the difference may be related to the spindle behavior changes, such as tripolar spindle formation and spindle rearrangement in the gynogenetic crucian carp. | YANG ZHONG AN QUN HUA LI YU FENG WANG JIAN FANG GUI (State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China) | 1999 | Cell Research1999，9，2： | 4 |
| 14 | Hepatic Histopathological Characteristics and Antioxidant Response of Phytoplanktivorous Silver Carp Intraperitoneally Injected with Extracted Microcystins显示文摘Objective To investigate the hispathological characteristics and antioxidant responses in liver of silver carp after intraperitoneal administration of microcystins (MCs) for further understanding hepatic intoxication and antioxidation mechanism in fish. Methods Phytoplanktivorous silver carp was injected intraperitoneally (i.p.) with extracted hepatotoxic microcystins (mainly MC-RR and -LR) at a dose of 1000 μg MC-LReq./kg body weight, and liver histopathological changes and antioxidant responses were studied at 1, 3, 12, 24, and 48 h, respectively, after injection. Results The damage to liver structure and the activities of hepatic antioxidant enzymes including catalase (CAT), superoxide dismutase (SOD), and glutathione peroxide (GPX) were increased in a time-dependent manner. Conclusion In terms of clinical and histological signs of intoxication and LD50 (i.p.) dose of MC-LR, silver carp appears rather resistant to MCs exposure than other fishes. Also, the significantly increased SOD activity in the liver of silver carp suggests a higher degree of response to MCs exposure than CAT and GPX. | LI LI AND PING XIE Fisheries College of Huazhong Agricultural University, Wuhan 430070, Hubei, China Donghu Experimental Station of Lake Ecosystems, State Key Laboratory of Freshwater Ecology and Biotechnology of China, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, Hubei, China | 2009 | Biomedical and Environmental Sciences2009，22，4： | 4 |
| 15 | Quantitative assessment of toxic and nontoxic Microcystis colonies in natural environments using fluorescence in situ hybridization and flow cytometry显示文摘Toxic cyanobacterial blooms constitute a threat to human safety because Microcystis sp. releases microcystins during growth, and particularly during cell death. Therefore, analysis of toxic and nontoxic Microcystis in natural communities is required in order to assess and predict bloom dynamics and toxin production by these organisms. In this study, an analysis combining fluorescence in situ hybridization (FISH) with flow cytometry (FCM) was used to discriminate between toxic and nontoxic Microcystis and also to quantify the percentage of toxic Microcystis present in blooms. The results demonstrate that the combination of FISH and flow cytometry is a useful approach for studying the ecology of Microcystis toxin production and for providing an early warning for toxic Microcystis blooms. | GAN NanQin, HUANG Qun, ZHENG LingLing & SONG LiRong State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，8： | 3 |
| 16 | Transgenes in F_4 pMThGH-transgenic common carp (Cy-prinus carpio L.) are highly polymorphic显示文摘To gain information on the integration pattern of pMThGH-transgene, 50 transgenes were recovered from F4 generation of pMThGH transgenic common carp (Cyprinus carpio L.) and 33 recovered genes were analyzed. The restriction maps of these recovered genes were constructed by digestion with five kinds of enzymes. These transgenes can be classified into 4 types according to their restriction maps. Only one type of transgenes maintains its original molecular form, whereas the other three types are very different from the original one and vary each other on both molecular weight and restriction maps. This implies that the sequences of most transgenes have been deleted and/or rearranged during integration and inheritance. The results of PCR amplification and Southern blot hybridization indicate that MThGH in Type I transgene keeps intact but most of its sequence has been deleted in other three types. All these results suggest that transgenes in F4 generation of transgenic carp are highly polymorphic.
