摘要:
argonaute（AGO）蛋白家族成员在小核糖核酸（RNA）介导的转录后调控中有重要作用．通过拟南芥AGO蛋白家族的结构域及各类植物中的AGO蛋白的进化关系进行分析，发现AGO蛋白在植物中结构和进化相对保守．根据已有的芯片数据，对拟南芥中AGO蛋白家族的组织表达进行分析，发现某些AGO基因具有组织表达的特异性．进一步通过基因上游启动子响应元件分析，以及盐等胁迫下的芯片和反转录聚合酶链式反应（RT-PCR）实验数据分析，发现AGO2、 AGO3和AGO7等基因受到盐等非生物胁迫的诱导表达．初步探明了拟南芥中AGO基因家族在盐胁迫下的差异表达规律．
Abstract:
AGO family proteins play an important role in small RNA-mediated post-transcriptional regulation. Analyzing the domain and evolution of AGO family proteins in diverse plant species, we revealed that the structural organization of AGOs is evolutionally conserved between different plant species. Based on the experimental data, some AGO genes were specifically expressed in various tissues in Arabidopsis. Sequence analysis showed that there are abiotic stress related cis-acting elements in the promotors of AGO genes, microarray and RT-PCR data also indicated the expressions of AGO2, AGO3 and AGO7 genes are induced under salt and other abiotic stress conditions. This is the first study to demonstrate the differential expression patterns of AGOs under salt stress in Arabidopsis.
