Abstract
Abscission, shedding of plant organs, is regulated by developmental programs and environmental cues, which plays a crucial role in fruit production and crop yield in many plant species. Floral organ abscission in Arabidopsis occurs in the abscission zone (AZ) consisting of two neighboring cell types: residuum cells (RECs) that remain attached to the main plant body after abscission and secession cells (SECs) that are attached to the separated organs. RECs have been recently suggested to undergo transdifferentiation into epidermal cells. However, the intrinsic molecular mechanisms and extrinsic positional cues underlying this process are unknown. Here, using single-cell RNA sequencing, we show how RECs transdifferentiate into epidermal cells. Our study will help to understand molecular mechanisms of cellular plasticity in plants.
