| Summary: | The calcineurin B-like-interacting protein kinase (CIPK) protein family plays a key role in the plant calcium ion-mediated signal transduction pathway, which regulates a plant’s response to abiotic stress. <i>Nitraria sibirica</i> pall. (<i>N. sibirica</i>) is a halophyte with a strong tolerance for high salt environments, yet how it is able to deal with salt stress on a molecular level is still unknown. Due to their function as described in other plant species, <i>CIPK</i> genes are prime candidates for a role in salt stress signaling in <i>N. sibirica</i>. In this study, we identified and analyzed the phylogenetic makeup and gene expression of the <i>N. sibirica CIPK</i> gene family. A total of 14 <i>CIPKs</i> were identified from the <i>N. sibirica</i> genome and were clustered into seven groups based on their phylogeny. The promoters of <i>NsCIPK</i> genes contained multiple elements involved in hormonal and stress response. Synteny analysis identified a total of three pairs of synteny relationships between <i>NsCIPK</i> genes. Each gene showed its own specific expression pattern across different tissues, with the overall expression of <i>CIPK6</i> being the lowest, and that of <i>CIPK20</i> being the highest. Almost all CIPK genes tended to respond to salt, drought, and cold stress, but with different sensitivity levels. In this study, we have provided a general description of the <i>NsCIPK</i> gene family and its expression, which will be of great significance for further understanding of the <i>NsCIPK</i> gene family function. |
