The cytokinin oxidase/dehydrogenase(CKX)enzyme is essential for controlling theﬂuctuating levels of endogen-ous cytokinin(CK)and has a signiﬁcant impact on different aspects of plant growth and ***-less,there is limited knowledge about CKX genes in tomato(Solanum lycopersicum L.).Here we performed genome-wide identiﬁcation and analysis of nine SlCKX family members in tomatoes using bioinformatics *** results revealed that nine SlCKX genes were unevenly distributed onﬁve chromosomes(Chr.1,Chr.4,Chr.8,Chr.10,and Chr.12).The amino acid length,isoelectric points,and molecular weight of the nine SlCKX proteins ranged from 453 to 553,5.77 to 8.59,and 51.661 to 62.494 kD,*** localization analysis indi-cated that SlCKX2 proteins were located in both the vacuole and cytoplasmic matrix;SlCKX3 and SlCKX5 pro-teins were located in the vacuole;and SlCKX1,4,6,7,8,and 9 proteins were located in the cytoplasmic ***,we observed differences in the gene structures and phylogenetic relationships of SlCKX proteins among different ***1-9 were positioned on two out of the three branches of the CKX phylogenetic tree in the multispecies phylogenetic tree construction,revealing their strong conservation within phylogenetic *** patterns of expression of CKX genes were noticed in callus cultures exposed to vary.ng con-centrations of exogenous ZT,suggesting their roles in speciﬁc developmental and physiological functions in the regeneration *** results may facilitate subsequent functional analysis of SlCKX genes and provide valu-able insights for establishing an efﬁcient regeneration system for tomatoes.
