Arabidopsis thaliana root responses to Cd exposure: insights into root tip‐specific changes and the role of HY5 in limiting Cd accumulation and promoting tolerance

Cadmium (Cd) is a major environmental pollutant with high toxicity. While Cd exposure reduces root growth, its specific impact on the root meristem and differentiating parts remains poorly understood. This study investigates the spatial and temporal responses of Arabidopsis thaliana roots to Cd stre
