The PbCYP78A6 transcript levels in fruitlets at distinct developmental stages and in different tissues of ‘Dangshansu’ pear. A The relative PbCYP78A6 expression levels were detected in reproductive tissues of 3-day-old pear flowers; B The PbCYP78A6 expression patterns in ‘Dangshansu’ fruitlets at early distinct stages; C Specific organs were sampled independently to detect the relative expression of PbCYP78A6 in 30-day-old pear fruitlets; D PbCYP78A6 transcript levels in different tissues of ‘Dangshansu’ fruitlets. An RT-qPCR analysis was used to determine the PbCYP78A6 transcript levels. UP: Un-pollinated; HP: Hand pollinated; GA₄: treated with 50 mg L⁻¹ GA₄; GA₃: treated with 50 mg L⁻¹ GA₃. DAA: days after anthesis. The results are represented as means of three biological replicates (± SDs). Significant differences (P < 0.05) among treatments as determined by a one-way ANOVA are indicated using different lowercase letters
