摘要： Environmental stresses significantly influence crop growth and productivity, acting as powerful selective pressures in plant evolution. The AP2/ERF superfamily is crucial for plant development and stress responses, orchestrating key regulatory pathways. This study explores the adaptive evolution of AP2/ERF genes across 15 key plant species, focusing on expansion and contraction patterns driven by amplification through multi-omics analyses. Across 15 plant genomes, we identified 1495 AP2/ERF genes. AP2/ERF genes demonstrated preferential retention following amplification, underscoring their importance in genomic stability and functional adaptation. Notably, the amplification-associated AP2 subfamily exhibited substantial expansion in quinoa (CqAP2/ERFs), emphasizing its role in stress adaptation. Robust regulatory networks were identified between CqAP2/ERFs, AtAP2/ERFs, and fatty acid pathways, highlighting their contributions to stress resilience. Transcriptomic analyses in Arabidopsis thaliana further validated the conserved correlation of these networks. Functional predictions based on phenotypic and RNA-seq data revealed the involvement of AP2/ERFs in key stress response and developmental processes. By integrating genomic, metabolomic, phenotypic, transcriptomic, and protein interaction data, this study uncovers novel regulators and adaptive pathways of AP2/ERFs, providing insights into their evolutionary diversification post-amplification. These findings establish a comprehensive framework for understanding the pivotal roles of AP2/ERFs in enhancing plant stress tolerance.
