Auxin accumulation patterns during AR formation in tomato plants. Confocal spectral laser scanning microscopy was used to image DR5pro:YFP (green) fluorescence localization during AR development in tomato stem cuttings. a Founder cells which arose from pericycle cells. Arrows point to cells with YFP signals. b Expanded AR founder cell cluster. Arrow points to cells with YFP signals. c Rudimentary AR primordium. Arrow points to cells with YFP signals. d, e Developing AR primordium. f Developing AR primordium vasculature. Arrows point to epidermal cells with YFP signals. g Two-fold magnification of (f). h Mature AR primordium emerging from stem. Arrows point to YFP signals in cell adjacent to AR primordium. i Emerged AR. Arrow points to cells with YFP signals. Bars=100 μm
