Gene expression in the tnp mutant. A and B, J2662 GFP expression in 7-d-old seedling of wild type (A) and tnp (B). C and D, J2601 GFP expression in 7-d-old seedling hypocotyl epidermal cells of wild type (C) and tnp (D). E to G, ARR5/IBC6∷GFP expression in the pericycle of 7-d-old seedlings of wild type (E) and tnp (F and G). H to J, SCR∷GFP expression in the endodermis of hypocotyls of 7-d-old seedlings of wild type (H) and tnp (I). J, Fresh transverse sections of wild-type (WT) and tnp seedlings. Arrow indicates SCR∷GFP expression in a vacuolated cell in the tnp section. K and L, CYCAT1:CDB:GUS activity in the hypocotyl of 7-d-old wild type (K) and tnp (L). Inset and arrows show cells that have undergone cell division.
