摘要： Parthenocarpy is a pivotal trait that enhances the yield and quality of fruit crops by enabling the development of seedless fruits. Here we unveil a molecular framework for the regulation and domestication of parthenocarpy in cucumber (Cucumis sativus L.). We previously discovered a natural non-parthenocarpic mutant and demonstrated that the AP2-like transcription factor NON-PARTHENOCARPIC FRUIT 1 (NPF1) is a central regulator of parthenocarpy through activating YUC4 expression and promoting auxin biosynthesis in ovules. A Phe-to-Ser substitution at amino acid residue 7 results in a stable form of NPF1 that is localized in the nucleus. An A-to-G polymorphism (SNP-383) within an NPF1-binding site in the YUC4 promoter significantly enhances the activation of NPF1 towards YUC4, leading to an increased rate of parthenocarpy. Additionally, NPF1 influences bitterness by reducing cucurbitacin C biosynthesis through the suppression of Bt expression. Our results suggest a two-step evolutionary model for parthenocarpy and fruit bitterness during cucumber domestication.
