“…To understand the phylogenetic relationship of olive CAMTAs, an unrooted phylogenetic tree is drawn and it is noticed that CAMTA proteins are grouped in 4 main branches and every branch contained A. thaliana CAMTA1 is present predominantly in the nuclei (Bouche et al, 2002). Also, in Fragaria × ananassa (Leng et al, 2015), P. trichocarpa (Wei et al, 2017), Gossypium species (Pant et al, 2018), in Triticum aestivum (Yang et al, 2020), in Linum usitatissimum (Ali et al, 2020), Oryza sativa (Gain et al, 2022) it was bioinformatically shown that CAMTAs are mostly localized in the nucleus.…”

Calcium is a secondary messenger which involves in stress response, adaptation, development and signaling pathways in plants.In cells, calcium is captured by calmodulin and after a conformation change, calmodulin becomes able to target calmodulin binding transcription factors. The calmodulin-binding transcriptional activators (CAMTAs) are one of these calmodulin binding transcription factors and they have CG-1, TIG, ANK, CaMBD and IQ conserved domains. CAMTAs are studied well in lots of plant species, and they are found to be involved in stress responses like drought, cold, salt and hormone responses like ethylene, abscisic acid, auxin, and gibberellin. In this study, CAMTA genes and proteins are characterized in olive. Olive (Olea europaea L.) is a Mediterranean commercially important crop, and this is the first study on olive CAMTAs. 7 CAMTA genes are found in olive in total in this study.Then, the cis-actin regulatory elements in the promoter regions of these genes are analyzed. Stress and hormone response related elements in the promoter regions are found, suggesting possible stress and hormone response roles of CAMTAs in olive. Also, protein characteristics, conserved domains, and subcellular localizations are investigated. According to the results, all olive CAMTA proteins are mainly localized in the nucleus as consistent with their roles, and all of them have 2 to 6 conserved domains which are also found in other plant CAMTAs. Additionally, a phylogenetic tree with 109 CAMTA proteins from well-knows plant species is constructed, and this tree showed that olive CAMTA proteins are highly conserved in plant kingdom.

“…It has been reported that fewer differentially expressed CAMTA factor genes were found in soybean roots than in soybean leaves [35]. CAMTAs have been shown to be extensively involved in plant growth and developmental regulation, as well as in biotic and abiotic stress tolerance [34]. In Arabidopsis, CAMTA1 and CAMTA2 genes use in concert with CAMTA3 to directly bind to the promoter of C-repeat binding factor2 (CBF2) to induce expression, leading to increased plant freezing tolerance.…”

The calmodulin-binding transcriptional activator (CAMTA) family has been known to be one of the fast responsive stress proteins. In this study, 17 CAMTA genes were selected in Arabidopsis, tomato and maize. The chromosomal distributions, gene structures, duplication patterns, phylogenetic tree, and developmental stage of the 17 CAMTAgenes in the three species were analyzed to further investigate their functions. According to the synteny analysis, CAMTA genes of maize and tomatorevealed higher similarity with each other as compared with Arabidopsis. A higher than 90 percent identity was observed between maize CAMTA genes (ZmCAMTA2 and ZmCAMTA3) and tomato CAMTA genes (SlCAMTA4, SlCAMTA4.1). To detect expression levels in different plant tissues, mRNA analysis of CAMTA genes were performed using publicly available expression data in the genvestigator. The aim of study was to identify and characterize CAMTA genes in three species, for the first time, via insilico genome-wide analysis approach. AtCAMTA1 and AtCAMTA2 and SlCAMTA2 and ZmCAMTA1 and ZmCAMTA2 genes were up-regulated during all developmental stages. The conserved motifs and gene structure in most proteins in each group were similar, validating the CAMTA phylogenetic classification. This study could be considered as a useful source for future CAMTA comparative studies in different plant species.
