Abstract
ABSTRACT
Fruit development typically follows pollination and fertilisation. However, parthenocarpy, the formation of seedless fruits, represents an alternative pathway. The fruit that grows from the ovary under unpollinated and/or unfertilised conditions is termed parthenocarpic. This trait is not only desirable to consumers but also contributes to yield stability under adverse environmental conditions. In this study, we demonstrate that overexpression of miR156h regulates parthenocarpy under unpollinated conditions via a gibberellic acid (GA)‐dependent pathway. MdSPL13B was found to be involved in MdmiR156h‐modulated GA accumulation and parthenocarpy through directly binding to the promoters of
