摘要: 根据已报道的刺甘草C4H基因序列(GenBank ID:D87520.1),采用RT-PCR技术克隆得到乌拉尔甘草悬浮细胞的C4H基因编码区序列,并对其进行生物信息学分析。另外,采用q-PCR方法对C4H基因受茉莉酸甲酯(Methyl jasmonate,MeJA)诱导后的表达模式进行分析。所克隆的C4H基因编码区开放阅读框(Opening reading frame,ORF)长为1 515 bp,编码504 个氨基酸。q-PCR实验证明C4H基因受MeJA的诱导,在悬浮体系添加MeJA后12 h达到最高表达水平。

Abstract: According to the reported C4H(cinnamate 4-hydroxylase)gene sequence(GenBank accession ID:D87520.1)from Glycyrrhiza echinata,the coding sequence of C4H gene from Glycyrrhiza uralensis Fisch suspension cultured cells was obtained by RT-PCR cloning technology,and the bioinformatics analysis on it was carried out. In addition,the expression patterns of C4H gene induced by methyl jasmonate(MeJA)were analyzed by q-PCR. The length of the cloned C4H’s open reading frame(ORF)was 1 515 bp,encoding 504 amino acids. The q-PCR experiments showed that C4H gene was induced by MeJA and reached the highest expression level at 12 h after MeJA added into the cell suspension system.
