“+” = up ‐regulated genes; “–” = down‐regulated genes; “±” = both up‐ and down‐regulated genes exist. The four symbols under each gene represent directional changes in expression in: Drought tolerant line DTL, in drought sensitive line DSL, Drought sensitive Parent DSP and Drought tolerant Parent DTP, respectively.TAA = tryptophan aminotransferase of Arabidopsis; YUCCA = flavin‐containing monooxygenase; Aux/IAA = auxin/indole acetic acid protein; GH3 = Gretchen Hagen 3; SAUR = small auxin‐up RNA; ARF = auxin response factor; GA2OX = gibberellin 2 beta‐dioxygenase; GA3OX = gibberellin 3 beta‐dioxygenase GID1 = GA insensitive DWARF1;NCED = 9‐cis‐epoxycarotenoid dioxygenase; CCD = carotenoid cleavage dioxygenases; HVA22= Hordeum Vulgare ABA induced protein ; ABF = ABA‐responsive element binding factors; ACO = 1‐aminocyclopropane‐1‐carboxylate oxidase; ACS = aminocyclopropane‐1‐carboxylic acid synthase; EBF1/2 = EIN3‐binding F‐box protein 1/2; EIN2 = ethylene‐insensitive protein 2; EIN3 = ethylene‐insensitive protein 3; ERF = ethylene response factor.OPR3 = 12‐oxophytodienoate reductase 3; JAZ1 = jasmonate‐zim‐domain protein 1; DET2= de-etiolated 2; BAK1= BRI1-associated receptor kinase 1; BRI; Brassinosteroid-Insensitive 1
