Identification and expression analysis of the ZF-HD gene family in castor
[Objective]The ZF-HD family genes of castor were identified and analyzed by sequence analy-sis,phylogenetic analysis,promoter and expression pattern analysis,to provide a reference for further study of the function of ZF-HD genes in castor.[Methods]Based on the whole genome data of castor,ZF-HD genes were identified,and bioinformatics and expression analysis under abiotic stress were carried out.[Results]A total of 13 ZF-HD genes were identified from castor,which were unevenly distributed on Chr1-Chr10.All 13 RcZF-HD proteins were hydrophilic unstable proteins,and were localized in the nucle-us.The RcZF-HD genes were clustered into three subgroups,and the number of genes in each group was different.The gene structure was conserved within the group but diversified between groups.RcZF-HD genes had a large number of tissue-specific elements,stress response elements,and hormone response ele-ments.The ZF-HD genes were widely responsive to abiotic stresses and their expression was tissue-spe-cific.[Conclusion]A total of 13 ZF-HD genes were identified in castor.It is known that members of the castor ZF-HD gene family play an important role in responding to abiotic stress,this research provides theoretical basis for the study of castor's stress resistance.
