Genome-Wide Identification of AP2/ERF Transcription Factors in Cauliflower and Expression Profiling of the ERF Family under Salt and Drought Stresses.

ABSTRACT: The AP2/ERF transcription factors (TFs) comprise one of the largest gene superfamilies in plants. These TFs perform vital roles in plant growth, development, and responses to biotic and abiotic stresses. In this study, 171 AP2/ERF TFs were identified in cauliflower (Brassica oleracea L. var. botrytis), one of the most important horticultural crops in Brassica. Among these TFs, 15, 9, and 1 TFs were classified into the AP2, RAV, and Soloist family, respectively. The other 146 TFs belong to ERF family, which were further divided into the ERF and DREB subfamilies. The ERF subfamily contained 91 TFs, while the DREB subfamily contained 55 TFs. Phylogenetic analysis results indicated that the AP2/ERF TFs can be classified into 13 groups, in which 25 conserved motifs were con
