Genome-Wide Identification of the AP2/ERF Transcription Factor Family and Expression Analysis Under Selenium Stress in <i>Cardamine hupingshanensis</i>.

ABSTRACT: AP2/ERF (APETALA2/ethylene-responsive factor) is one of the largest plant transcription factor families, characterized by 1-2 AP2/ERF domains (≈60-70 amino acids) that regulate plant development and biotic/abiotic stress responses. This study presents the first genome-wide identification and characterization of the AP2/ERF family in the selenium (Se) hyperaccumulator Cardamine hupingshanensis via bioinformatics. A total of 230 AP2/ERF genes were identified, which were non-randomly distributed across 16 chromosomes. Their encoded proteins varied in length (126-623 aa), molecular mass (13.927-68.112 kDa), and isoelectric point (4.48-10.31). Phylogenetic analysis classified these genes into five conserved subfamilies (AP2, DREB, ERF, RAV, Soloist), consistent with other plant sp
