The effect of IAA, ABA, SA, JA, NaCl, and cold on the expression of DR5::GUS in transgenic seedlings. GUS staining of representative root segments of DR5::GUS seedlings after treatment with (A) 10 μM IAA for an increasing number of hours, (B) 10 μM IAA and an increasing concentration of ABA for 3 h, (C) 10 μM IAA and an increasing concentration of SA for 3 h, (D) 10 μM IAA and an increasing concentration of JA for 3 h, (E) 10 μM IAA and an increasing concentration of NaCl for 12 h, and (F) 10 μM IAA and transfer to a growth chamber set at 4°C under the 16/8 h light/dark cycle for an increasing number of hours. Scale bars = 1 cm.
