Cadmium and copper-induced metabolic and proteomic changes in the root tip during early maize growth.

In this study, the metabolic adjustments performed by maize (Zea mays L.) seminal roots exposed to 25 µM Cd or 25 µM Cu at pre-emergence are compared, focusing on the proteomic changes after metal exposure. Root width was increased, and root length was decreased after 72 h of metal treatment.
