Calmodulin-Binding Transcription Factors: Roles in Plant Response to Abiotic Stresses
Plants face many abiotic stresses throughout their life cycle, such as drought, high temperature, low temperature, and salinity. To survive and reproduce, plants have evolved a complex and elaborate signal transduction network to sense stress signals and initiate corresponding defense mechanisms. Ca...

| description | Plants face many abiotic stresses throughout their life cycle, such as drought, high temperature, low temperature, and salinity. To survive and reproduce, plants have evolved a complex and elaborate signal transduction network to sense stress signals and initiate corresponding defense mechanisms. Calcium ion (Ca<sup>2+</sup>), as a secondary messenger, plays an important role in mediating signal transduction in plant cells. Calmodulin (CaM) is an important class of Ca<sup>2+</sup> receptors that sense changes in cellular calcium ion concentration and can interact with a range of proteins to regulate the activity of downstream target proteins. Calmodulin-binding transcription factors (CAMTAs) are a family of transcription factors (TFs) that are widely present in plants and can bind to CaM. The CAMTAs are regarded as the most characterized CaM-binding TF family in the plant Ca<sup>2+</sup> signaling pathway. In recent years, studies have shown that CAMTAs play an important regulatory role in plant abiotic stress response and plant growth and development. Therefore, this review summarizes the recent progress in the discovery, structure, and role of CAMTAs under abiotic stresses, with a view to providing a reference for future CAMTA studies. Finally, the prospects and directions for further research on the potential mechanisms of CAMTAs in plants are also discussed. |
