Figure Lengend Snippet: Analysis of the VvSUN promoter and location analysis of VvSUN . (A) VvARF6 interfaces with the VvSUN promoter, as shown by a Y1H assay. As bait, Y1H strains containing the promoters of VvSUN were employed in the experiment. pGADT7 was set as the vector for the control. (B) Measurement of GUS expression levels in grapevine leaves was accomplished based on the transient expression of the VvSUN promoter in response to varying dosages of IAA treatment. The 35S promoter acted as the positive control. Outcomes are presented as the means (± standard deviation) of three biological experiments. Lower-case letters ( P ≤ .01) and capital letters ( P ≤ .05) represent a significant difference among different treatments, as determined by Student’s t -test. (C) Histochemical staining of GUS function mediated by the VvSUN promoter under different concentrations of IAA treatment in grapevine leaves. The 35S promoter is the control and P0, P10, P50, and P100 represent the 0, 10, 50, and 100 mg/l IAA treatments, respectively. (D) Subcellular distribution of VvSUN in the leaves of N. benthamiana that had been transiently converted. 35S-GFP was adopted as the control, and expression was monitored utilizing a confocal laser scanning microscope. Chlorophyll channel (left 1), GFP channel (left 2), bright field (right 2), and merged images (right 1) are shown.
