Abstract:

【Objective】 To clone and study the sequence characteristics of the glutathione-S-transferase, (GST) gene from the Vitis vinifera L.cv ‘Munage’ table grapes in the hope of laying a foundation for the disease resistance and function of this gene in grape fruit.【Methods】 Full-length VvGST1 gene cDNA was isolated from grape fruit according to the existed ESTs sequence,and 3' and 5' end of the RACE primers were designed by using RT-PCR and RACE.【Results】 A variety of bioinformatics analysis methods were used to predict and analyze the gene, and the results showed that the ORF (Open Reading Frame) length was 719 bp, which encoded a 221 amino acid polypeptide.The VvGST1 gene was forecasted and the relative molecular mass of encoding the protein was 25.55 kDa, the theoretical isoelectric point was 6.32, the atomic composition was C1178H1799N293O321S11.Its instability coefficient was 39.22, showing it was astable hydrophilic protein without signal peptide or transmembrane structure.It might exist in the cell matrix and was a typical matrix protein.Through analyzing the evolutionary tree, the amino acid sequence of VvGST1 was clustered with cotton, peach, prunus, cherry, plum, chestnut and other plants, among which it was closely related to cotton.【Conclusion】 The full-length coding region of VvGST1 gene in Vitis vinifera L.cv ‘Munage’ table grapes is successfully obtained,and the structural characteristics of the sequence are confirmed.

摘要:

【目的】克隆木纳格葡萄果实中谷胱甘肽-S-转移酶(glutathione-S-transferase,GST)基因VvGST1全长并研究其序列特征,为该基因在葡萄果实抗病作用和功能的研究奠定基础。【方法】根据已有的基因序列,设计3'和5'端RACE引物,利用RT-PCR和RACE技术克隆VvGST1基因cDNA全长。【结果】该基因序列全长719 bp,均为开放阅读框(ORF),共编码221个氨基酸。该基因编码蛋白相对分子质量为25.55 kDa;理论等电点pI值为6.32;分子式为C1178H1799N293O321S11;不稳定指数为39.22;该蛋白质是稳定的亲水性蛋白,不含跨膜结构域,没有预测到信号肽,可能存在于细胞基质中,是典型的基质蛋白。VvGST1氨基酸序列与棉花、桃、西梅、樱桃、李子、板栗等植物聚为一类,其中与棉花属亲缘关系最近。【结论】获得了木纳格葡萄谷胱甘肽-S-转移酶VvGST1基因全长编码序列,探明了该序列的结构特征。
