a–k Expression patterns of pDR5v2::nls-3xVenus (a, b), pYUC4::3xNLS-GFP (c, d), pPIN1::PIN1-GFP (e–g), pPIN3::PIN3-GFP (h, i), and pPIN7::PIN7-GFP (j, k) in the A. thaliana gynoecium. Virtual cross sections shown in (b, d, f) are in the middle of the gynoecium. g, i, k Heat-maps represent the intensity of the PIN1-GFP (g), PIN3-GFP (i), and PIN7-GFP (k) signal in the L1 epidermal layer (one side of the gynoecium tops are shown for PIN1 and the style is shown for PIN3 and PIN7). Insets indicate membrane localization and arrows indicate plausible orientation of PIN polarization. Scale bars, 100 µm in (a, c, e, h, j) and 50 µm in (b, d, f, g, i, k).
