摘要:以牡丹品种‘赵粉’为试材,采用RT-PCR和RACE方法从花瓣中获得1个牡丹APETALA2基因cDNA全长,命名为PsAP2,GenBank登录号为HM167511。序列分析结果表明:PsAP2全长2138bp,包含47bp的5'非编码区、557bp的3'非编码区和1个长度为1533bp编码510个氨基酸的开放阅读框。氨基酸序列分析显示该基因属于AP2家族。序列比对和系统进化分析表明,PsAP2与葡萄的亲缘关系最近,相似性达70%以上。相对荧光定量PCR分析表明,PsAP2在根、茎、叶和四轮花器官中均有表达。花瓣中的表达量最高,叶片中表达量最低。
In this work,a full-length cDNA sequence of APETALA2 gene was obtained from petals of Paeonia suffruticosa 'Zhaofen' using RT-PCR and RACE,named PsAP2(GenBank accession No.HM167511).Sequence analysis indicated that PsAP2 is 2 138 bp in full length,containing a 5'-untranslated region(5'-UTR) of 47 bp,a 3'-UTR of 557 bp,and an opening reading frame(ORF) of 1 533 bp encoding a 510 predicted amino acids,and belongs to AP2 family.Sequence alignment and phylogenetic analysis revealed that PsAP2 shared more than 70% homology with Vitis vinefera.Relative Real-Time PCR analysis indicated that PsAP2 expressed in roots,stems,leaves and four floral organs.The expression in petals was the highest and the expression in leaves was the lowest.
