No expression in the root apical meristem. In flowers, restricted to the vascular bundles and transmitting tissue of developing gynoeciae.DEVELOPMENTAL STAGE:Expressed during the maturation phase of stomatal guard cells but not in fully mature stomata. In the root vasculature, detected soon after germination, with a maxima around the lateral root primordia.SIMILARITY:Belongs to the oxygen-dependent FAD-linked oxidoreductase family."
