Comprehensive Analysis of Calcium Sensor Families, CBL and CIPK, in and Their Expression Profile in Response to Salinity.

Plants have acquired sets of highly regulated and complex signaling pathways to respond to unfavorable environmental conditions during evolution. Calcium signaling, as a vital mechanism, enables plants to respond to external stimuli, including abiotic and biotic stresses, and coordinate the basic processes of growth and development. In the present study, two calcium sensor families, CBL and CIPK, were investigated in a halophyte plant, , with a comprehensive analysis. Here, six genes, and twenty genes were studied. The analysis of the gene structure and conserved motifs, as well as physicochemical properties, showed that these genes are highly conserved during evolution. The expression levels of genes and genes were evaluated under salt stress in leaf and root tissue. Based on the real-time RT-PCR results, the gene family had a higher variation in mRNA abundance than the gene family. genes were found to have a higher abundance in leaves than in roots. The results suggest that the correlation between genes and is tissue-specific, and different correlations can be expected in leaves and roots. Based on these correlations, AlCIPK3.1-AlCBL4.1 and AlCIPK1.2-AlCBL4.4 can be co-expressed in the root tissue, while AlCBL10 has the potential to be co-expressed with AlCIPK5, AlCIPK26, and AlCIPK12.3 in the leaf tissue. Our findings reveal valuable information on the structure and function of calcium sensor families in a halophyte plant, that can be used in future research on the biological function of CBLs and CIPKs on salt stress resistance.
