Fc-vasa mRNAs were detected by RT-PCR in early developmental stages from 2-cells embry to intramembranous nauplius, and not in any stages after nauplius. Based on above results, it is postulated that Fc-vasa is required for germ cell determination and formation of F. chinensis as a maternal component.
但表达量逐渐降低，自出膜后的无节幼体开始检测不到表达信号，根据以上结果推测，Fc-vasa mRNA可能作为母源生殖质成分参与中国明对虾生殖细胞的决定和形成。

We hope that the results could offer reasons for studies of biology of development, genetics and physiology of nutrition in the ontogenetic periods of Coelomactra antiquata and for breeding parents with highquality, regulation of procreation and prevention of damage by disease in "863"project:《Cosmically cultivation of Coelomactra antiquata》.The results showed as below: Distribution and activities of different isozymes in different tissues were differential and relative to their functions.
通过本文的研究，希望可以为更加深入地进行西施舌的发育生物学、遗传学以及幼体发育变态过程中的营养生理学研究提供有价值的参数，同时也为国家"863"计划《西施舌的大规模人工育苗》中优质亲贝培育、生殖调控技术及病害预防等问题提供一定的理论依据。

neoteny：幼态成熟
有些鲵螈类,例如巴尔干半岛地下水中的洞螈,北美的泥螈,中国的山溪鲵和滇池蝾螈 (Cy-nopus wolterstorffi) 等在性成熟和具有生殖能力时, 仍保留着幼体时期的某些特征, 这种现象称为幼态成熟(neoteny).处于幼态时期的动物就能进行生殖的现象,

paedogenesis：幼体生殖
有人认为在寒武纪早期,尾索动物的幼虫发生了幼体生殖(paedogenesis)的现象,其生殖器官在变态之前就成熟了. 经过了天择,尾索动物的幼虫发展出了分节的肌肉和强壮的骨骼来支撑身子,并且因为头的形成对适应环境有相当的优越性,

polyembryony：多胚生殖
多胚生殖(polyembryony)是指1个卵内可产生两个或多个胚胎,并能发育成正常新个体的生殖方式. 少数昆虫在幼虫期就能进行生殖,称为幼体生殖. 因其幼虫期即具生殖能力,又行腺养胎生,所以幼体生殖属孤雌生殖和胎生. 其成熟卵无卵壳,
