PbCYP78A6 overexpression contributed to reduced seed numbers and parthenocarpy in tomato. A Longitudinal sections of wild-type and transgenic fruits produced by natural pollination at the green ripened stage; B Longitudinal sections of wild-type and transgenic fruits produced by natural pollination at the ripened stage; C The percentages of PbCYP78A6-overexpression (OE) fruits containing different numbers of seeds under natural pollination conditions; D Seeded fruit produced by hand pollination, and parthenocarpic fruit resulting from the emasculation of PbCYP78A6-OE lines; E The parthenocarpic fruit set rates of emasculated transgenic PbCYP78A6-OE tomatoes; F Histological observations of hand-pollination emasculated and emasculated transgenic PbCYP78A6-OE tomato pericarps at about 10 days after full-bloom. Bars = 200 μm in emasculated wild-type, other bars = 500 μm in F. The results represented are 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. Bars = 2 mm in A and B
