Genome-Wide Identification of the AP2/ERF Gene Family and Functional Analysis of <i>PgAP2/ERF187</i> Under Cold Stress in <i>Panax ginseng</i> C. A. Meyer.

ABSTRACT: Panax ginseng C. A. Meyer (P. ginseng) is a medicinal plant rich in bioactive components such as ginsenosides, polysaccharides, and volatile oils and is widely used in both the pharmaceutical and food industries. While the AP2/ERF gene family is well-documented to play crucial roles in plant growth, development, and defense responses, functional studies on this gene family in P. ginseng remain unreported. Our genome-wide analysis identified 318 PgAP2/ERF family members, which are classified into five subfamilies: AP2, DREB, ERF, RAV, and Soloist. Homology analysis revealed that segmental duplication serves as the primary evolutionary driver for the PgAP2/ERF gene family in P. ginseng. RT-qPCR analysis demonstrated that all PgAP2/ERF members in the
