Relative expression levels of the DhMYB1 cDNA in different floral tissues of floral buds. a Representative semi-quantitative RT-PCR results for DhMYB1 and β-actin cDNA in sepals, petals and labella of stage 5 to 7 floral buds. Lane 1: stage 5 sepals; lane 2: stage 5 petals; lane 3: stage 5 labella; lane 4: stage 6 sepals; lane 5: stage 6 petals; lane 6: stage 6 labella; lane 7: stage 7 sepals; lane 8: stage 7 petals; lane 9: stage 7 labella; lane 10: negative control. b Relative intensity of PCR bands for DhMYB1 normalized to the constitutive β-actin gene. Each bar represents the mean for three biological replicates with error bars indicating the SE. Letters indicate significant differences using one way ANOVA followed by Tukey HSD multi-comparison analysis test (P < 0.05)
