In response to various stressors, the calmodulin-binding transcription activator (CAMTA) can regulate downstream genes involved in calcium (Ca2+)/calmodulin signaling after binding to calmodulin (CAM) or calmodulin-like (CML) proteins. We previously reported seven OsCAMTA genes available throughout the rice (Oryza sativa) genome and their docking with the best probable interactors. This refned study demonstrated the evolutionary conservation of OsCAMTA motif structure and its correlation with 41 diferent plant species through phylogenetic tree construction along with the detailed molecular docking study focusing specifcally on the calmodulin-binding domain (CaMBD) of each CAMTA protein with all avail- able CAM/CML proteins across the rice genome. More insights regarding these were obtained from gene duplication studies through synteny analysis. Protein–protein interactions by STRING database analysis were conducted to know the involvement of OsCAMTA proteins in various development and stress-dependent pathways by identifying probable interac- tors. Tissue-specifc expression analysis through qRT-PCR revealed that all the OsCAMTA genes except OsCAMTA7a and OsCAMTA7b were abundantly expressed in the roots of rice plants. Transcript expressions of rice CAMTAs under diferential salt concentrations have depicted their participation in salt stress activity. Gene expression analysis in various temperatures indicated the most up-regulation of OsCAMTA7b, OsCAMTA4 and OsCAMTA3b at 4 ºC, 37 ºC and 42 ºC, respectively. In comparison to earlier research on OsCAMTA genes, this study is the most comprehensive fne-tuned and well-honed research conducted through tissue-specifc expression study, followed by spatio-temporal expression analysis under diferent stresses with protein–protein interaction studies, molecular docking and prediction of microRNA to target each of the OsCAMTAs.
