The APETALA2/ethylene-responsive factor (AP2/ERF) has important roles in regulating developmental processes and hormone signaling transduction in plants. Pineapple demonstrates a special sensitivity to ethylene, and AP2/ERFs may contribute to this distinct sensitivity of pineapples to ethylene. However, little information is available on the AP2/ERF of pineapple. In this study, 97 AP2/ERF family members were identified from the pineapple genome. The AcAP2/ERF superfamily could be further divided into five subfamilies, and different subfamily existed functional divergence in multifarious biological processes. ERF and RAV subfamily genes might play important roles in the process of ethylene response of pineapple; ERF and DREB subfamily genes had particular functions in the floral organ development. This study is the first to provide detailed information on the features of AP2/ERFs in pineapple, provide new insights into the potential functional roles of the AP2/ERF superfamily members, and will facilitate a better understanding of the molecular mechanism of flower in pineapple.

APETALA2/乙烯反应因子（AP2/ERF）在调控植物发育过程和激素信号转导中具有重要作用。菠萝表现出对乙烯的特殊敏感性，而 AP2/ERF 可能有助于菠萝对乙烯的这种独特敏感性。然而，关于菠萝的 AP2/ERF 的信息很少。在这项研究中，从菠萝基因组中鉴定出 97 个 AP2/ERF 家族成员。AcAP2/ERF超家族可进一步分为5个亚家族，不同亚家族在多种生物学过程中存在功能分歧。ERF和RAV亚家族基因可能在菠萝乙烯反应过程中发挥重要作用；ERF和DREB亚家族基因在花器官发育中具有特殊功能。
