FIGURE 4.

Binding preferences of TCP proteins and the corresponding mutants in vivo in yeast. Yeast strains carrying a fusion of oligonucleotides C16 or C20 (six copies) to the LacZ gene containing a minimal promoter were transformed with constructs expressing the indicated TCP proteins fused to the GAL4 activation domain. Values indicate the specific β-galactosidase activity of the strain carrying the C20 construct divided by the activity of the one carrying the C16 construct and indicate a relative preference for C20 or C16 whether they are >1 or <1, respectively. The mean (±S.D., error bars) of three independent measurements is shown.
