Genome-wide analysis of AP2/ERF transcription Factors in <i>Cymbidium sinense</i> reveals their impact on orchid diversity.

ABSTRACT: Cymbidium sinense is a significant traditional Chinese horticultural crop, valued both economically and ornamentally. The APETALA2/ethylene response factor (AP2/ERF) transcription factors play crucial roles in regulating growth, development, cell differentiation, and responses to both biotic and abiotic stresses in plants. However, the regulatory functions of AP2/ERF factors in C. sinense remain poorly understood. In the present study, 116 AP2/ERF genes were first identified from C.sinense genome. Based phylogenetic analysis, these genes were categorized into five groups: AP2, RAV, ERF, DREB, and Soloist. Within the ERF group, two subtypes were identified: ERF (containing six subtypes from ERF B1 to ERF B6) and DREB (containing six subtypes from DREB A1 to DREB A6), co
