Figure 2

(a) Overview of the genes induced and/or repressed by NAA and naxillin treatments after 2 h or 6 h. (b) Longitudinal enrichment in NAA-responsive (light gray) and naxillin-responsive (dark gray) genes. L, longitudinal section. (c–h) Five-day-old pDR5::GUS seedlings grown on control medium (c,d) and transferred to 10 μM naxillin (e,f) or 10 μM NAA (g,h) for 8 h and stained for β-glucuronidase activity. Panels d, f and h are sections at the basal meristem zone of pDR5::GUS seedlings indicated in c, e and g respectively. Asterisks indicate phloem poles; crosses indicate xylem pole pericycle (XPP) cells; arrows in e and f indicate GUs staining in XPP cells. Scale bars, 10 μm.
