B. Relative expression changes of HSP70.3, HSP70.4 and HSP90.1 in bes1-D as compared to wild-type following heat shock. 14-day-old plants were exposed to 45°C for 60 minutes, expression was analyzed by qPCR and the results were normalized to UBC. Data show the mean ±SD. n=3 biological replicates measured in 3 technical repeats. Significant differences as compared to wild-type at 45°C, calculated by Student's t-test, are shown (*P≤0.05).
