The Gibberellin‐Responsive Module RsRGL3a‐RsGID1b‐1‐ RsATL56 Orchestrates Parthenocarpic Fruit Formation in Seedless Chestnut Rose ( Rosa sterilis )

Summary statement Seedlessness is a fruit trait highly favoured by consumers, with parthenocarpy serving as an important means to achieve seedless fruit. In this work, RsGID1b‐1 responds to GAs and promotes parthenocarpic fruitsetting by activating RsATL56 transcription in seedless chestnut rose ( Rosa sterilis ). RsRGL3a antagonizes RsGID1b‐1 and represses RsATL56 , negatively regulating parthenocarpy.
