早期

Was exchange an early agent of human evolution or is it merely an artefact of modern civilisation?

交换是否为人类进化的早期动因？还是仅为现代文明的人造物？

Keywords: Artemia from China;early embryonic development;related genes;mRNA differential display

In this experiment, the related genes of early embryonic development of Chinese Artemia Pathenogenatica have been studied by mRNA Differential Display.

本研究采用mRNA差异显示方法分离中国孤雌生殖卤虫早期胚胎发育相关基因。

The fragments showing low degree of similarity to previously reported genes may be new genes. The further research on these sequences is very useful to obtain the complete genes and to know the mechanism of early embryonic development of Chinese Artemia Parthenogenetica.

其它同源性较低的片段可能为未知新基因，对这些序列信息进行进一步研究将有助于获得完整基因和了解中国孤雌生殖卤虫早期胚胎发育的机制。

MRNA differential display was established by Liang and Pardee in 1992 for the purpose of displaying the mRNA differences between two tissues. Therefore, in the study, the related genes of early embryonic development of bisexual Artemia from Shan Xi in China have been studied by mRNA Differential Display.

但关于中国卤虫早期发育过程中基因表达的研究很少，还有待于进一步深入细致的研究和分析。mRNA差异显示法是由Liang和Pardee于1992年建立起来的，是用于显示不同组织和细胞之间mRNA差异的方法。
