C. Immunodetection of native BES1 from heat-stressed and epiBL-treated abitM plants. abitM and wild-type plants were grown on ½ MS medium either containing DMSO as a control or 1 μM epiBL and either left untreated or exposed to 45°C for 60 minutes. The non-phosphorylated BES1 bands were quantified with ImageJ and the obtained values are shown in blue.
