| 1 | 鱼类远缘杂交育种技术的建立及应用显示文摘杂交是广泛应用的重要育种技术,然而,在鱼类中,杂交育种长期以来缺乏系统的理论和技术支撑.通过长期的系统研究,本课题组探索出了鱼类远缘杂交相关的遗传和繁殖规律,形成了适合于远缘杂交和近缘杂交的一步法育种技术和多步法育种技术,创制了一批二倍体鱼品系和四倍体鱼品系,研制了一批优良鱼类.另外,通过查阅国内外有关鱼类杂交的相关文献,对鱼类杂交育种途径、技术方法及效果等进行了广泛讨论.该文对鱼类杂交育种研究及应用具有重要的参考价值. | 王石 汤陈宸 陶敏 覃钦博 张纯 罗凯坤 赵如榕 王静 任力 肖军 胡方舟 周蓉 段巍 刘少军 | 2018 | 中国科学:生命科学2018，48，12： | 18 |
| 2 | 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 |
| 3 | Differential expression and characterization analysis of a new gene with WD domains in fish oogenesis显示文摘A new gene with WD domains is cloned and characterized according to its differential transcription and expression between previtellogenic oocytes (phase I oocytes) and fully-grown oocytes (phase V oocytes) from natural gynogenetic silver crucian carp (Carassius auratus gibelio)by using the combinative methods of suppressive subtraction hybridization, SMART cDNA synthelowed by an open reading frame of 990 bp, which has the typical vertebrate initiator codon of Antranslated region and an AATAAA polyadenylation signal. Because it has 92% homology to STRAP (serine-threonine kinase receptor-associated protein), a recently reported gene, we named it FSTRAP (fish STRAP). Virtual Northern blotting indicated that the FSTRAP was transcribed in fully-grown oocytes (phase V oocytes), but not in previtellogenic oocytes (phase I oocytes).RT-PCR analysis showed that FSTRAP was transcribed in brain, heart, kidney, muscle, ovary,spleen and testis, but not in liver. And its mRNA could be detected in the oocytes from phase II to phase V. Western blotting also showed that FSTRAP protein could be detected in brain, heart,kidney, muscle, ovary, spleen and testis except liver. Results of Western blotting on various oocytes were also similar to the RT-PCR data. FSTRAP protein was not expressed in the previtelIogenic oocytes. Its expression initiated from phase II oocytes after vitellogenesis, and was consistent with the mRNA transcription. | 文建军 谢京 刘世贵 桂建芳 | 2001 | Science China(Life Sciences)2001，44，5： | 11 |
| 4 | Establishment and application of distant hybridization technology in fish显示文摘Hybridization is widely used. However, for a long time, systematic theories and technologies related to hybridization in fish have been lacking. In this study, through long-term systematic research, we investigated and obtained the main rules regarding inheritance and reproduction related to fish distant hybridization. Furthermore, we established one-step and multistep breeding technologies that were suitable for interspecific hybridization and intraspecific hybridization. Simultaneously, we used these two breeding technologies to produce a batch of diploid fish lineages and tetraploid fish lineages and improved fishes. In addition, we widely discuss the methods, technologies and results of hybridization breeding, referring to the domestic and foreign literature on fish hybridization. We hope that this paper will be beneficial for the research and application of fish hybrid breeding. | Shi Wang Chenchen Tang Min Tao Qinbo Qin Chun Zhang Kaikun Luo Rurong Zhao Jing Wang Li Ren Jun Xiao Fangzhou Hu Rong Zhou Wei Duan Shaojun Liu | 2019 | Science China(Life Sciences)2019，62，1： | 6 |
| 5 | In vitro culture of embryonic hearts from guppy fish (Poecilia reticulata)显示文摘Forty embryonic hearts were taken out by anatomical needle from denuded embryos of the ovovivipar-ity guppy fish that were dechorioned by mechanic method or by trypsin digestion, and were in vitro cultured. In the cultured hearts, 80% have maintained beating in vitro for 4 weeks, and the longest record for beating was 142 d. Owing to fish embryo transparency, beating frequency and blood color changes are easily viewed from the embryonic hearts under a dissecting microscope. The current study established the in vitro culture method of embryonic hearts in guppy fish, which can be used as a model for the study of heart and cardiovascular system in vertebrates. | Qiya Zhang Zhenqiu Li Jianfang Gui | 2001 | Chinese Science Bulletin2001，46，19： | 0 |
