摘要

本研究以光滑鳖甲幼虫的cDNA为材料

应用抑制差减杂交(Suppression Subtractive Hybrriization

SSH)技术构建细菌诱导的光滑鳖甲幼虫抑制差减cDNA文库

并利用反向Northern杂交技术获得差异基因.结果表明

随机挑取的阳性克隆的大小均为20(0~750 bp

符合差减文库PCR产物片段的大小.通过斑点杂交技术共筛选出940个差异基因片段

对其克隆、测序及同源性分析后鉴定出70种编码蛋白的基因ESTs序列

所得ESTs序列主要涉及免疫防御、代谢过程、生长发育类等相关基因.细菌诱导光滑鳖甲幼虫抑制差减cDNA文库的构建

为进一步克隆光滑鳖甲免疫抗菌相关基因及其免疫防御机制的研究奠定了基础.

Abstract

In the present study

suppression subtractive cDNA library was constructed for Anatolica polita borealis larva induced by bacteria using suppression subtractive hybridization(SSH) technique

and differential genes were obtained by reverse Northern blot.The results showed that the randomly selected positive clones were all in 200-750 bp

in accord with the prediction for PCR

940 differential genes fragments were screened by dot blot hybridization.The expressed sequence tags(ESTs) sequences of 70 proteins were identified by sequence and homology analysis.The ESTs sequences were mainly involved in immune defense

metabolic processes

growing development

and other related genes.Construction of suppression subtractive cDNA library of A.polita larva induced by bacteria

for further cloning A.polita immune antibacterial related gene and its immune defense mechanism research laid the foundation.
