Quantitative assay results for BpMYC4 and BpbHLH9 in birch saplings treated by different hormones. The relative expressions of BpMYC4 and BpbHLH9 were quantified by quantitative RT-PCR. Reported values are the means of three replicates, and standard errors are indicated as vertical lines on the top of each bar. * Indicates a significant difference between the control and experimental treatments (P < 0.05). ** Indicates a highly significant difference between the control and experimental treatments (P < 0.01)
