Characterization of fruit and buds in transgenic and wild-type plants. a The whole fruit bunch of wild-type plants; b The whole fruit bunch of transgenic plants; c Comparison of male flower buds from wild-type and transgenic plants. Bar = 5 cm; d Comparison of fruit fingers between wild-type and transgenic plants. Bar = 1 Cm. e Expression analysis of TPD1 homologs in WT and MaTPD1A-OE line. The gene expression values are relative to that of the wild-type plant (set as 1). The experiments are performed three times, and one representative experiment is presented. RE indicates relative expression level. Significant differences were determined using Student’s t-test (**P < 0.01). Bars indicate standard deviation, ns means not significant
