Unraveling the mechanisms of fruit abscission in <i>Morus laevigata</i> through multi-omics approaches.

ABSTRACT:

Introduction

Morus laevigata (long-fruited mulberry) is rich in active components and possesses significant nutritive value. The fruitlet stage represents a critical period for fruit abscission, and elucidating the underlying biological mechanisms of this process can provide a theoretical foundation for breeding more stable and abscission resistant cultivars.

Methods

Fruit peduncles at the fruit set stage (April to May) were selected as experimental materials, including both abscising and non-abscising fruits. Morphological analysis of the peduncle abscission zone was conducted to examine structural differences. Additionally, transcriptomic and metabolomic analyses were performed to investigate gene expression and metabolite changes associated with fruit abscission.
