From: ERF49 mediates brassinosteroid regulation of heat stress tolerance in Arabidopsis thaliana
Exogenous 2, 4-eBL treatment and endogenous BR increase thermotolerance of Arabidopsis thaliana. a The influence of different concentrations of 2, 4-eBL on heat tolerance of Arabidopsis thaliana. b Survival rate of A. thaliana treated with 2, 4-eBL in a heat stress environment. c The thermotolerance of BR biosynthesis and signaling transduction mutants. d The survival rate of BR biosynthesis and signaling transduction mutants after heat stress treatment. Seven-day-old seedlings were treated under 42 °C for 3 h and recovery for 5 days. Sixty to eighty seedlings of each genotype from three biological replicates were counted. Asterisks represent statistical significance (****, P < 0.0001; one-way ANOVA followed by post hoc Tukey’s multiple comparison test). Numerical data is provided in Additional file 6. Experiments were repeated for three times, the error bars indicate standard deviation
