摘      要：Cytokinins are a class of phytohormones that promote cell division and differentiation and are thought to affect plant immunity to multiple ***,a comprehensive analysis of cytokinin dehydrogenase/oxidase(CKX)family genes in cabbage has not been *** this study,a total of 36 CKX genes were identified using a genome-wide search *** analysis classified these genes into three *** were distributed unevenly across nine chromosomes in ***,and 15 of them did not contain any *** results of colinearity analysis showed that 36 CKX gene in Arabidopsis was present in several copies in the Brassica oleracea *** analysis of cisacting elements indicated that all genes possessed at least one stress or hormone responsive cis-acting element.A heatmap of CKX gene expression showed the patterns of expression of these genes in various tissues and *** genes(Bol028363,Bol031036 and Bol018140)were relatively highly expressed in all of the investigated tissues under normal conditions,showing the expression profile of housekeeping ***,the expression patterns of CKX genes in Jingfeng 1 and Xiangan 336 were quite different under the same ***,three genes(Bol020547,Bol028392 and Bol045724)were significantly down-regulated and up-regulated in the susceptible and resistant material,respectively,after inoculation,which may indicate their crucial roles in resistance to clubroot *** results provide insights for better understanding the roles of CKX genes in the ***–*** interaction.
