Fig. 5 A comparison of the VaSTS19 and VdSTS19 promoter sequences The translational start sites（+1）are shown in red box. Motifs with significant similarity to previously identified cis-acting elements in both species are shaded in green. Motifs found only in VaSTS19 or VdSTS19 promoters are respectively shaded in pink or red. Arrowheads pointing to the left represent the reverse direction of cis-elements compared to promoter orientation. Other arrows represent start point of 5′-deleted derivatives.

Fig. 7 GUS activity analysis of promoter fragments of different lengths of VaSTS19 and VdSTS19 in response to hormone treatment in transiently transformed tobacco leaves Mean GUS activity（± SE）is averaged from triplicate experiments. WT：Wild type；N：Negative control（no promoter）；35S：Positive control （CaMV35S promoter）. Significant difference test were evaluated using a one-sided paired t test（**α = 0.01，or at *α = 0.05）.
