The tropical plant  Plumbago auriculata  can tolerate subzero temperatures without induction of apoptosis after cold acclimation in autumn, making it more cold tolerant than conventional tropical plants. In this study, we found that low temperatures significantly affected the photosynthetic system of  P. auriculata . Using transcriptome sequencing,  PaDREB1A  was identified as a key transcription factor involved in the response to cold stress in  P. auriculata . This transcription factor may be regulated by upstream JA signaling and regulates downstream  ERD4  and  ERD7  expression to resist cold stress. Overexpression of  PaDREB1A  significantly enhanced freezing resistance, protected the photosynthetic system, and enhanced the ROS scavenging mechanism under cold stress in  Arabidopsis thaliana . Additionally,  PaDREB1A  significantly enhanced the expression of  CORs  and  CAT1  in  A. thaliana , which further activated the downstream pathway to enhance plant cold tolerance. This study explored the possible different regulatory modes of  CBFs  in tropical plants and can serve as an important reference for the introduction of tropical plants to low-temperature regions.
