(a–c) Confocal images of epidermal cells of N. benthamiana leaves 36 hr after Agrobacterium-mediated transient expression of the indicated constructs. Bars = 10 µm. (d–f) GFP lifetime distribution of GFP-MYB30, or GFP-MYB123, in nuclei of N. benthamiana cells expressing the C-terminus of SBT5.2(b) [SBT5.2(b)341-730], or SBT5.1 [SBT5.1405-780], as indicated. Histograms show the number of nuclei according to GFP-MYB30, or GFP-MYB123, lifetime classes when the MYB protein is expressed alone (green bars) or in the presence of RFP-tagged SBT5.2(b)341-730, or SBT5.1405-780, (magenta bars), as indicated. The degree of overlap of GFP lifetime distribution is represented with magenta (+RFP-tagged SBT constructs) and green (GFP-tagged MYB constructs) arrows.
