Fig. 3 Insertion mutation in the BnaBZR1 promoter changed the BnaBZR1 gene expression, did not change the interaction of BnaBZR1 with BnaPIF4 A: sequence analysis of insertion mutation regions in the promoter of BnaBZR1; B: analysis of the interaction between BnaBZR1 and BnaPIF4 by yeast hybridization; C: the temporal and spatial gene expression of BnaBZR1 in XY881 and XY883; D: the expression of BnaBZR1 in XY881 and XY883 under poor light stress and 2,4-BL treatment. DAG means days after seed germination.
