AP2/ERF基因家族转录因子普遍存在于植物中,参与植物体内的各种生物学过程,包括植物的生长发育、生物和非生物胁迫响应等。前期转录组测序的结果发现马铃薯‘加湘1号'一个AP2/ERF家族基因(PGSC0003DMG400012154)在接种晚疫病菌(Phytophthora infestans) 24 h后被显著激活。从接种P. infestans 24 h的‘加湘1号'的总RNA中通过RT-PCR获得了该基因CDS序列为885 bp,BLAST分析显示该基因编码一个295个氨基酸残基的蛋白,并且含有1个AP2/ERF结构域,是AP2/ERF转录因子家族中的ERF亚家族的一员。本研究将该基因与Xcm I酶切的表达载体pCXSN连接,转化大肠杆菌,通过测序挑选插入正确克隆酶切验证,并成功转化...

AP2/ERF gene family is a special transcription factor in plants, which participates in the regulation of gene expression related to plants development and biotic or abiotic stresses. Previous transcriptome sequencing results showed that the expression of an AP2/ERF gene (PGSC0003DMG400012154) of potato 'Jiaxiang 1' was significantly increased 24 h after inoculation with Phytophthora infestans. The CDS of PGSC0003DMG400012154 was obtained by RT-PCR from the total RNA of 'Jiaxiang 1' 24 h after inoculation with P. infestans. The CDS of the AP2/ERF gene was 885 bp, encoding a 295 amino acids prot...
