Analysis of transgenic Arabidopsis lines under heat stress. Phenotypes of WT and TaWRKY33 transgenic Arabidopsis lines under heat stress (a). Sruvival rates of WT and TaWRKY1 transgenic Arabidopsis lines under heat stress (b).  Sruvival rates of WT and TaWRKY33 transgenic Arabidopsis lines under heat stress (c). Seeds from three independent transgenic lines of TaWRKY1 and TaWRKY33 were grown on MS medium. Five-day-old seedlings were heat-treated at 45 °C for five h before returning them to 22 °C to continue to grow vertically for 2 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
