Histochemical analysis of pNPC4:GUS expression in Al-treated Arabidopsis seedlings. Ten-day-old Arabidopsis seedlings grown on agar were transferred to liquid 1/8 MS solution with or without AlCl3 for 24 h. Final observations were done on a zoom stereoscopic microscope. This experiment was repeated twice with similar results.
