利用构建的黑胸大蠊浓核病毒全基因组重组质粒(PfDNV-pUC119)以及一系列完整缺失克隆，通过全自动测序方法完成了PfDNV两末端各728 bp 和730 bp 核苷酸序列的测定。

As the bar gene is promoted by the CaMV35 promoter, in which there is a 19bp palindromic sequence could act as recombination hot spot and lead to DNA rearrangement, we presumed that the transgene recombination events happened during the integration course have generated the complex Southern patterns of bar gene expression cassette.

线形基因表达框的游离DNA末端和CaMV35S启动子中重组热点介导的转基因重组可能是导致bar基因表达框复杂整合的重要原因。

Compared the similarity and difference of distribution of homologous fragments on X and Y, we suggested that the sex chromosomes of spiny eel have evolved from a pair of homologous ancestral chromosomes, and during the evolution, a pericentric inversion might have occurred on the original Y chromosome, and subsequently terminal regional duplication might have followed, eventually resulting in the differentiation and formation of X and Y chromosomes, then the recombinants between sex chromosomes were repressed, so the sex chromosomes could be inherited steadily.

根据X、Y染色体上同源片段的分布的相似和相异，我们对刺鳅性染色体的分化历程进行了推测，即：刺鳅的性染色体起源于一对原始的同源染色体，通过原Y染色体上的一个明显的臂间倒位，以及染色体末端的异染色质成分的扩增，导致原始Y染色体与X染色体在染色体结构上的分化，从而抑制了X、Y性染色体之间的遗传物质的重组交换，为性染色体的稳定遗传奠定了基础。
