Palindrome sequence is very common in DNA,it usually acts as cis-elements of many regulative factors.
本文设计了不同长度的回文结构序列 ,构建了Cre loxP重组系统 ,通过共转化含有cre基因的质粒和含有loxp位点的质粒 ,观察共转化菌株质粒图谱的变化 ,研究了重组系统在细菌中对基因表达的作用 ,同时研究不同长度回文结构对基因表达的影响 ,结果发现长度在 2 0bp以下回文序列对下游基因的表达没有影响 ,而长于 3 4bp的回文结构序列则会抑制下游基因的表
The SOS boxes sequence in the 2 positive fragments were identified by DNase Ⅰ foot printing testing,and the palindrome sequence in the 2 SOS boxes was analyzed.
方法挑选铜绿假单胞菌PAO1株基因组中16个可能含有SOS盒序列的DNA片段,经PCR扩增后,用纯化的LexA表达蛋白做凝胶滞后实验;将获得的2个阳性DNA片段进一步用DNaseⅠ足纹法进行LexA蛋白结合序列即SOS盒的鉴定;分析所获得的2个SOS盒中的回文序列,以此回文序列在PAO1基因组中进行检索,初步分析出可能的SOS盒序列和可能的调控基因。
Two kinds of Rep-PCR, Repetitive extragenic palindromic elements-PCR(REP-PCR) and en-terobacterial repetitive intergenic consensus sequences-PCR (ERIC-PCR), were used firstly in typing and genetic relationship research for Vibrio parahaemolyticus in China, and Hunter&Gaston’s method was used to calculate discriminative index of REP-PCR and ERIC-PCR.
