Characterization of CBL-Interacting Protein Kinases’ Gene Family and Expression Pattern Reveal Their Important Roles in Response to Salt Stress in Poplar
The CBL-interacting protein kinases’ (CIPKs) gene family plays an important role in plants under salt stress. In this study, a total of 31 <i>PtrCIPK</i> genes were identified in poplar. CIPKs’ gene family was divided into two categories, few intron classes and multi-intron classes. They...

| description | The CBL-interacting protein kinases’ (CIPKs) gene family plays an important role in plants under salt stress. In this study, a total of 31 <i>PtrCIPK</i> genes were identified in poplar. CIPKs’ gene family was divided into two categories, few intron classes and multi-intron classes. They all have the core components of the kinase domain and regulatory domain unique to the <i>CIPK</i> gene family and share most of the same motifs. <i>PtrCIPKs</i> have 17 fragment repeat events and have high homology with <i>Arabidopsis thaliana</i> and <i>Betula platyphylla</i>, and partial homology with <i>Zea mays</i>. Prediction of cis-acting elements found that the <i>PtrCIPK</i> gene family has the most elements in terms of stress. Under NaCl stress, all members of poplar CIPKs’ gene family were significantly expressed. There were fourteen up-regulated genes and four down-regulated genes. Candidate gene expression was significantly higher in the phloem than in other tissues. In this study, characterization of CBL-interacting protein kinases’ gene family and expression pattern reveal their important roles in response to salt stress in poplar. |
