文昌鱼

In the present study, the acute and sub-acute toxicity of copper on amphioxus and rosy barbs was investigated.

采用半静水实验法测试研究了重金属Cu(上标 2+)对文昌鱼和玫瑰无须鲃的急性致死毒性和亚急性毒性。

In order to develop the animal into a new laboratory model, we sampled two species of amphioxus （ Branchiostoma belcheri and B.

要实现文昌鱼的模式动物化，实验室内全人工条件下繁殖是关键的第一步。

The gut cDNA library of amphioxus has been constructed by the method of LD PCR.

本文还利用LD PCR方法成功地构建了青岛文昌鱼的消化道cDNA文库。

Recently, the studies for the origin of the AIS focus on seeking evidence of the existence of adaptive immune system in amphioxus.

由于文昌鱼在进化上的特殊地位，近年来成为众多免疫学家研究的热点。

Amphioxus is expected to be a model laboratory animal in the near future because of its important position in evolution, simplified internal organ systems and transparent body.

文昌鱼特殊的进化地位、简单的器官系统和终生透明的躯体等特征，使其很有希望成为一个新型实验室模式动物。

It suggested that GDF8/11 gene might possess additional functions other than regulating muscle growth in amphioxus.

这表明GDF8/11在文昌鱼中除了调节肌肉生长外还可能拥有其他的功能。

This favors that amphioxus retains a genome uncomplicated by extensive gene duplication.

这支持了文昌鱼基因组没有发生广泛倍增的观点。

RT-PCR reveals a ubiquitous expression pattern of amphioxus NM23-Bbt2 in all adult tissues and it was also expressed in all stages during the embryogenesis.

RT-PCR分析表明文昌鱼NM23-Bbt2在所检测的组织和胚胎发育时期中的非特异性的表达模式。

All these results support the notion that amphioxus is not only the sister group of the existing vertebrates but also the basal lineage of chordates.

我们的结果说明，文昌鱼不仅是脊椎动物的姊妹类群，而且是脊索动物谱系进化过程中的基部类群。

For sub-lethal tests, both rosy barbs and amphioxus were exposed to selected concentrations of copper.

亚急性毒性实验中，文昌鱼和玫瑰无须鲃分别用浓度为20%和30%的96h LC50的Cu(上标 2+)处理。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
