important role in cytokinin regulatory processes. CKX proteins are encoded by a multigene
family with a varying number of members. In this study, 13 maize CKX sequences were
collected in which ten transcripts were confirmed by RT-PCR. The tissue-and cytokinin-
dependent expression studies indicated that ZmCKX genes exhibit a variety of expression
patterns, suggesting diverse functions. Besides 13 maize CKXs, 7 Arabidopsis, 9 poplar …
