摘　　要：SBP基因家族是植物体中特异性存在的一类重要转录因子,主要功能是调控生物生长以及细胞分化。此次研究采用生物信息学的方法,对拟南芥SBP蛋白序列进行系统进化分析,并为其构建了系统发育树。由试验结果可以得出,拟南芥SBP基因家族共包括30个成员,分布在4条染色体上,其分布比较集中,分成三大亚族。拟南芥SBP蛋白具有的生物功能是控制生物生长以及细胞分化,调节基因表达以及谷胱甘肽的分解代谢过程,在Cu2+跨膜转运中也有一定作用。另外,有许多的蛋白序列还具有分子功能——调控转录因子活性。该研究所得结果均为拟南芥SBP转录因子的进一步功能分析提出了重要研究依据。The SBP gene family which existed in the specificity of the plant corpus is a kind of important transcriptional factor and its main function is to regulate and control biological growth and cell differentiation.In this study,bioinformatics methods were used to systematically analyze the sequence of A.thaliana SBP protein and build the phylogenetic tree for the sequence of A.thaliana SBP protein.The result of the experiment shows that the family includes 30 members,which is distributed on four chromosomes intensively and are divided into three subtribe.The biological function of A.thaliana SBP protein is a process of not only controlling biological growth and differentiation of cells,but also regulating gene expression and glutathione catabolism and it also plays an important role in the copper ions transport membrane.In addition,a great number of protein sequences have molecular function-regulating and controlling the activity of transcription factors.The results of this study provide important research basis for further functional analysis of A.thaliana SBP transcription factors.
