Whole genome-wide identification of CIPK family and their expression characteristics under abiotic stress in Sorghum bicolor
Calcineurin B-like proteins interacting protein kinase(CIPK)is an important Ca2+signal sensor,which plays an important role in plants'response to abiotic stress.In order to explore the function of CIPK family gene members in Sorghum bicolor'a total of 31 SbCIPK genes were identified,which were unevenly distributed on nine chromosomes from Sor-ghum bicolor in this study.The length of the SbCIPKs encoded proteins ranged from 403 to 519 aa,the isoelectric points ranged from 6.07 to 9.38,and the relative molecular weights ranged from 46 357.31 to 58 316.97.The SbCIPK gene family members were divided into intron deletion type and intron enrichment type by gene structure analysis.According to the results of phylogenetic tree analysis,the S.bicolor SbCIPK family protein members were divided into eight subgroups.SbCIPK genes were widely involved in abiotic stress responses to salt and drought and so on based on the published transcriptome data.These results can lay the foundation for the functional study of SbCIPK family members in S.bicolor.
