Cloning and expression analysis of ascorbate peroxidase gene BoAPX from Brassica oleracea var. italica(青花菜抗坏血酸过氧化物酶基因BoAPX的克隆与表达分析)
根据NCBI基因数据库提供的抗坏血酸过氧化物酶(Ascorbate Peroxidase,APX)基因序列设计简并引物,以青花菜(Brassica oleracea var. italica)叶片cDNA和DNA为材料进行PCR扩增,基因定名为BoAPX (Gen-Bank登录号:HQ871864).BoAPX的基因组全长为1 394 bp,具7个内含子,编码区全长为753 bp,编码250个氨基酸残基.序列分析结果表明,BoAPX的N端中没有信号肽序列,为胞质型APX,BoAPX与已知APX具有较高的同源性.RT-PCR结果表明,BoAPX的表达受霜霉菌(Hyaloperonospora p...
