Total root lengths of transgenic Arabidopsis lines under mock drought stress. Phenotypes of WT and TaWRKY33 transgenic Arabidopsis seedlings under MS medium with or without 6 % PEG6000 (a). Root lengths of WT and TaWRKY1 transgenic Arabidopsis seedlings grown on MS medium with or without 4 and 6 % PEG6000 (b).  Root lengths of WT and TaWRKY33 transgenic Arabidopsis seedlings grown on MS medium with or without 4 and 6 % PEG6000 (c). Five-day-old Arabidopsis seedlings were planted on MS medium with or without 4 and 6 % PEG6000 for seven days. Data are means ± SD of three independent experiments and * above the error bars or different letters above the columns indicate significant differences at p <0.05
