Extended Data Fig. 1: Wound-induced callus activates cambium-related markers but not root regeneration-related markers.
From: Water availability positions auxin response maxima to determine plant regeneration fates
a–d, Expression patterns of fluorescence reporters (magenta) for WOX11 (de novo root regeneration (DNRR) marker), LBD1 and PXY (cambial markers) in the Arabidopsis leaf petiole on day 0 (a) or during DNRR (b), wound-induced callus (WIC) (c), or hormone-induced callus (HIC) from unwounded tissues (d) on day 5. Dashed lines indicate the regenerating root primordium in (b). Calcofluor white (grey) was used to stain cell walls. The corresponding representative bright-field images of the detached leaf (a), DNRR (b), WIC (c) and HIC (d) at 0, 8 or 12 days are shown in the left panel. Scale bar: 500 µm for the bright-field images, 100 µm for the confocal images. Confocal experiments were independently performed 3 times with similar results.
