Genome-wide identification and comparative analysis of the AP2/ERF gene family in Prunus dulcis and Prunus tenella: expression of PdAP2/ERF genes under freezing stress during dormancy.

ABSTRACT: The AP2/ERF (APETALA2/ethylene responsive factor) transcription factor family, one of the largest in plants, plays a crucial role in regulating various biological processes, including plant growth and development, hormone signaling, and stress response. This study identified 114 and 116 AP2/ERF genes in the genomes of 'Wanfeng' almond (Prunus dulcis) and 'Yumin' wild dwarf almond (Prunus tenella), respectively. These genes were categorized into five subfamilies: AP2, DREB, ERF, RAV, and Soloist. The PdAP2/ERF and PtAP2/ERF members both demonstrated high conservation in protein motifs and gene structures. Members of both families were unevenly distributed across eight chromosomes, with 30 and 27 pairs of segmental duplications and 15 and 18 pairs of tandem repeated genes, respectively. The
