Calmodulin‐binding transcription activator (CAMTA) is a calmodulin‐binding transcription factor that has a broad range of functions from sensory mechanisms to regulating many growth and developmental processes. In this study, we isolated four strawberry CAMTA ( FaCAMTA ) genes using HMMER and BLAST analysis. The chromosome scaffold locations of these CAMTA genes in the strawberry genome were determined and the protein domain and motif organization [CG‐1, transcription factor immunoglobulin, ankyrin (ANK) repeats, calmodulin‐binding IQ motif) of FaCAMTAs were also assessed. All FaCAMTAs were predicted to be Ca‐ and calmodulin‐binding proteins. The expression profiles of FaCAMTA genes were measured in different tissues and revealed distinct FaCAMTA gene expression patterns under heat, cold, and salt stress. These data not only contribute to a better understanding of the complex regulation of the FaCAMTA gene family but also provide evidence supporting the role of CAMTAs in multiple signaling pathways involved in stress responses. This investigation can provide useful information for further study.
