Application of microinjection method in amphioxus and functional study of Pax1/9 gene

Abstract

文昌鱼的器官构造和基因组成都较为简单,是研究胚胎发育机制以及脊椎动物器官起源的理想材料。然而,作为一种新兴的模式动物,目前文昌鱼研究领域的常用实验技术仍比较单一。显微注射技术是发育生物学研究中的一项重要实验技术,但是至今文昌鱼卵显微注射技术的应用还很不成熟。本文以白氏文昌鱼为材料,优化了文昌鱼显微注射步骤,用诱导产出的未受精卵进行显微注射,建立了一套高效的文昌鱼卵显微注射方法,并分别以KCl、β-actin启动子驱动的LacZ报告基因重组质粒以及Rfp报告基因重组质粒为注射溶液,通过统计注射后的受精率、胚胎发育时的出膜率、正常发育率以及胚胎表达LacZ和Rfp信号的阳性率对建立的显微注射技术进...Amphioxus is now believed to be a promising model animal for evolutionary and developmental studies for its simple body plan and genome content. However, as an emerging model organism, amphioxus is lack of most molecular techniques applied in other well-developed model animals. Microinjection is a powerful technique for gene manipulation, and thus is one of useful approaches in the studies of gene...学位:理学博士院系专业:生命科学学院_遗传学学号:2162011015394
