The AT-hook motif nuclear localized (AHL) gene family is a highly conserved transcription factor critical for the growth, development, and stress tolerance of plants. However, the function of the AHL gene family in Brassica rapa (B. rapa) remains unclear. In this study, 42 AHL family members were identified from the B. rapa genome and mapped to nine B. rapa chromosomes. Two clades have formed in the evolution of the AHL gene family. The results showed that most products encoded by AHL family genes are located in the nucleus. Gene duplication was common and expanded the BrAHL gene family. According to the analysis of cis-regulatory elements, the genes interact with stress responses (osmotic, cold, and heavy metal stress), major hormones (abscisic acid), and light responses. In addition, the expression profiles revealed that BrAHL genes are widely expressed in different tissues. BrAHL16 was upregulated at 4 h under drought stress, highly expressed under cadmium conditions, and downregulated in response to cold conditions. BrAHL02 and BrAHL24 were upregulated at the initial time point and peaked at 12 h under cold and cadmium stress, respectively. Notably, the interactions between AHL genes and proteins under drought, cold, and heavy metal stresses were observed when predicting the protein-protein interaction network.
