  1. Data for responses in shoots or seedlings were selected. ABA: 10 uM abscisic acid for 1 h; ethylene: 10 uM ACC for 3 h; BL: 10 nM brassinolide for 3 h; CK: 1 uM zeatin for 3 h; auxin: 1 uM IAA for 3 h; JA: 10 uM methyl jasmonate for 3 h; SA: 10 uM salycilic acid for 3 h; H2O2: 3% solution for 3 h; drought: 1 h-treatment; DREB1Aox: constitutive overexpression of DREB1A driven by a 35S promoter. 1Count of complementary sequence is merged because REG is defined as orientation-insensitive.
