胚胎

Because the vertebrates express anatomical characteristics consistently during the process of fetation, many researchers conjectured ancient vertebrates by the characteristics of the animals living nowadays and speculate the origin and the process of evolution.

由於所有的脊椎动物在其胚胎发育中都呈现连续的解剖学特徵，因此过去很多学者都根据现存脊椎动物的形态特徵和在其发育过程中的解剖学特徵假想原始脊椎动物，并推导其进化过程和起源。

Although water temperature is little different,the speed of fetation for Pangasius sutchi is more faster than Pelteobagrus fulvidraco(55 h15 min),Pelteobagrus vachelli(49 h5 min),Silurus soldatovi meridionalis Chen(53 h25 min),they belong to Siluriformes,and Hypophthalmichthys molitrix(31 h35 min),Sillago sihama(36 h30 min),Gerres(32 h),Stizostedion luciopera(106 h),they are not.

虽然水温稍有不同，苏氏圆腹鱼芒的胚胎发育速度比同属鲶形目的鄱阳湖黄颡鱼(55 h15 min)、瓦氏黄颡鱼(49 h15 min)、南方大口鲶(53 h25 min)和不同目的白鲢(31 h35 min)、多鳞鱚(36 h30 min)、银鲈(32 h)、梭鲈(106 h)要快得多。

Forced expression of fez induces ectopic expression of dlx2 and dlx6, two genes involved in brain development.

通过显微注射含有Fez基因的DNA或mRNA使该基因在野生型斑马鱼胚胎中超表达，可以诱导两个与脊椎动物前脑发育相关的基因dlx2和dlx6发生提前和异位的表达。

Our studies indicate that fez is one of the earliest markers specific for the anterior neuroectoderm and it may play a role in forebrain development by regulating Dlx gene expression.

本文的研究证实Fez基因是最早在胚胎前端神经外胚层中表达的标志性基因之一，并有可能是通过调节Dlx系列基因的表达而在前脑发育过程中起作用。
