摘要: 拟南芥AtSb10基因是一个表达谱和功能都未知的基因,生物信息学分析发现其氨基酸序列含有2个连续的MATH结构域。为分析AtSb10基因的功能,首先,利用RT\|PCR方法检测AtSb10基因在拟南芥中的表达模式,结果表明,该基因只在根中表达,而茎、叶片、花与果荚中未检测到;然后克隆了AtSb10基因全长,构建了过量表达载体,通过农杆菌介导法将该载体转入拟南芥Col\|0中,获得了10株过表达转基因植株,为进一步研究AtSb10基因的功能奠定了基础。

Abstract: Bioinformatic analysis suggested that AtSb10, whose function and expression profile were unknown, contained two consecutive MATH domain structures. In order to further explore the function of AtSb10 gene, RT\|PCR was used to investigate the expression profile of Atsb10 in Arabidopsis thaliana. The results showed AtSb10 gene was expressed only in roots, not in stems, leaves, flowers and siliques. Meanwhile, full\|length of AtSb10 was cloned into overexpression binary vector pCAMBIA1300 driven by the CaMV35S promoter. Then this expression vector was transformed into Columbia\|0 ecotype mediated by Agrobacterium tumefaciens GV3101. Ten over\|expression transgenic plants were obtained, which would provide good materials for further studying on the function of Atsb10.
