Introduction

Background

This exploratory data analysis examines differential gene expression in Arabidopsis thaliana abscission zone mutants. Abscission is the controlled detachment of plant organs such as flowers and fruits, occurring at specialized abscission zones (AZs). The development and activation of these zones are regulated by both hormonal signals, primarily auxin and ethylene, and key transcription factors.
