Changing paradigms for the micronutrient zinc, a known protein cofactor, as a signal relaying also cellular redox state. [PDF]
Quant Plant BiolThe micronutrient zinc (Zn) is often poorly available but toxic when present in excess, so a tightly controlled Zn homoeostasis network operates in all organisms. This review summarizes our present understanding of plant Zn homoeostasis.
