APETALA 2/乙烯反应元件结合因子(AP2/ERF)转录因子在植物生长发育和逆境响应中发挥重要作用。目前已有4种蔷薇科植物的全基因组测序完成，但尚未见有关蔷薇科植物AP2/ERF基因家族全基因组分析的报道。本研究从中国李(Prunus Mume)中鉴定了116个AP2/ERF基因。根据AP2/ERF结构域的数目，这些PmAP2/ERF基因被分为三个家族(AP2、ERF和RAV)，并有一个成员。ERF家族被细分为11个组。其中22个PmAP2/ERF基因参与节段性复制，41个参与串联复制。通过共线分析，确定了73个PmAP2/ERF基因在拟南芥中可能是同源基因。转录组测序分析表明，PmAP2/ERF基因的表达差异很大。
The APETALA 2/ethylene-responsive element binding factor (AP2/ERF) transcription factors play important roles in plant development and responses to stress. Although the entire genomes of four Rosaceae species have been fully sequenced, no genome-wide analysis of AP2/ERF gene family has yet been reported in the Rosaceae family. In this study, 116 AP2/ERF genes were identified from Chinese plum (Prunus mume). Based on the number of AP2/ERF domains, these PmAP2/ERF genes were classified into three families (AP2, ERF, and RAV) along with a single member. The ERF family was subdivided into 11 groups. Of those, 22 and 41 PmAP2/ERF genes were involved in segmental and tandem duplications, respectively. Putative orthologs in Arabidopsis were identified for 73 PmAP2/ERF genes following synteny analysis. Transcriptome sequencing analysis showed that expression of PmAP2/ERF genes was widely variable.
