Calcium (Ca2+) plays a pivotal role in various signal transduction pathways. Calcineurin B-like proteins (CBLs) are unique group of Ca2+ sensors that decode signals by activating the plant specific protein kinase known as CBL-interacting (CIPK). In plants, CBL-CIPK signaling network regulates multiple response to different extracellular cues including abiotic stress. However, genome wide annotation and expression patterns CBLs CIPKs woody cutting flower plants still unclear. this study, total number 7 (RcCBLs) 17 (RcCIPKs) genes, divided into four five subfamilies, respectively, were identified from rose genome. All RcCBLs possess classic elongation factor-hand (EF-hand) domain, while all RcCIPKs both NAF domains. Most predicted be plasma membrane localized, whereas most cytoplasmic localized. Synteny analysis showed one RcCBL gene pair RcCIPK pairs have gone through whole duplication events. Promoter cis-element prediction assays indicated could function stress responses plants. Further quantitative real-time PCR demonstrated expressed organs with overlapped but distinct stresses. The findings work will provide fundamental information resources for further functional research on RcCIPKs.
