Caption: Fig. 3. Model of auxin flow during leaf and leaf vascular system initiation. (A) In the SAM, auxin transported towards primordia (P) is effectively depleting the surrounding epidermis of auxin. At sites least affected by the depletion (i.e., at maximum distance from pre-existing primordia), auxin is transported in all directions through the epidermis towards an auxin maxima (black and white arrows) leading to the formation of a convergence point (CP red) to mark the site of new primordium initiation. (B) Enlarged view of the box in (A). At the primordia tip, auxin transport is turned towards subepidermal tissue (internalized), where it continues in the tip-to-base direction delineating the path of a subsequently forming vascular strand. (C) Leaf lamina with major and minor veins. (D) Expanded view of the box in (C). Auxin is transported through just a single cell file in the epidermis of the leaf margin, to form convergence points associated with the main (1°) and second (2°) order veins; the higher order (h) veins are either open with auxin transport oriented towards the major veins or they connect through bipolar cells to form loops (l). Figure 3a modified from figure 5 in Reinhardt et al. 2003 and figures 2a–2c in Berleth et al. 2007; Fig. 3c modified from figure 2f in Berleth et al. 2007; Fig. 3d modified from figure 7c in Scarpella et al. 2006. www.nrcresearchpress.com/journal/cjb
