摘要:

为了获得高山红景天中红景天苷生物合成关键酶—— UDP- 糖基转移酶家族基因的全长cDNA 序列,采用在线简并引物设计软件结合3′-RACE 技术获得两个糖基转移酶基因的3′端部分序列,进一步采用不同的5′-RACE试剂盒扩增两个基因的5′端序列,结果显示利用Takara 公司的试剂盒扩增可以得到cDNA全长序列(GenBank登录号为EF508689 和EU567325),而采用Invitrogen 公司的试剂盒得到的序列不包括全部开放读码框。实验证明,利用Takara 公司的SMARTerTM RACE cDNA Amplification Kit 克隆获得基因全长序列的比率更高。

Abstract:

In order to obtain the critical enzyme for the synthesis of Rhodiola sachalinensis glycoside, two putative UDPglycosyltransferase (UGT) cDNAs (GenBank accession number, EF508689和EU567325) were isolated from R. sachalinensi. The primers were designed for 3'-rapid amplification of cDNA ends (RACE) based on the consensus hybrid oligonucleotide primers (CODEHOP) strategy by the Block Maker program. A full-length cDNA sequence (Genbank accession numbers: EF508689 and EU567325) was obtained through the amplification using a SMARTerTM RACE cDNA Amplification Kit (TaKaRa, Dalian, China), whereas the sequence obtained using a 5'-RACE system (version 2.0, InvitrogenTM Life Technologies) contained no full-open reading frame.The cloning efficient of two 5'-RACE systems was investigated. Results exhibited that TaKaRa SMARTerTM RACE cDNA Amplification Kit was more efficient in complete cDNA sequence cloning, compared with the InvitrogenTM 5'-RACE system.
