- 摘要:
- 磺基转移酶( sulfotransferase,SULT ) 基因是一个基因超家族。对大豆磺基转移酶基因GmST1( Glyma. 13G191400) 进行基于生物信息学的基因结构分析与功能预测,结果表明: GmST1( Williams82) 基因序列全长1 439 bp,CDS 区长1 035 bp,编码344 个氨基酸。通过序列比对,分析出在感病Williams 82 和抗病品种东农93-046中,GmST1 序列存在着非同义SNP,导致氨基酸改变。利用PlantCARE 分析启动子元件,发现在基因启动子序列中含有多个与光诱导、生长素、水杨酸、干旱等相关的元件。在BAR 数据库中分析了GmST1 的拟南芥同源基因在不同逆境胁迫条件下基因表达情况,表明该基因表达具有组织表达特异性,参与盐胁迫、干旱胁迫和抗病等相关反应。
- Abstract:
- Sulfotransferase( SULT) is a gene superfamily. In this study,we mainly analyzed the structure and function of ST1gene in soybean based on bioinformatics. The results showed that the full sequence length of GmST1( Williams 82) was 1 439bp. The CDS was 1 035 bp in length, encoding 344 amino acids. By sequence alignment, one non-synonymous SNP was foundbetween Williams 82 and Dongnong 93-046, leading to the changes of amino acid. There were multiple cis-elements about lightresponses,SA,drought and auxin in promoter sequence region detected by PlantCARE. The Bio-Analytic Resource for PlantBiology database was used to analyze the different expression of the homologous gene of GmST1 in Arabidopsis. The results indicatedthat the gene had tissue-special expression and was involved in salt,drought and diseases responses.
