Expression pattern of the AtPUB46-48 promoters. Arabidopsis plants expressing the GUS reporter gene driven by the AtPUB46 (a-i) AtPUB47 (j-r) or AtPUB48 (s-aa) promoters were stained for GUS activity. (a, j, s), 2 week old seedlings; (b, k, t), rosette leaves of mature plants; (c, l, u), trichomes; (d, e, m, n, v, w), primary roots, root hairs and developing lateral roots; (f, o, x), root tips; (g, p, y) shoot-root transition zone; (h, q, z) flowers; (I, r, aa), siliques. At least 3 independent lines were assayed for each construct
