What is Cadmium‐mediated toxicity in plant cells is associated with the DCD/NRP‐mediated cell death response about?

## Abstract Cadmium (Cd^2+^) is highly harmful to plant growth. Although Cd^2+^ induces programmed cell death (PCD) in plant cells, Cd^2+^ stress in whole plants during later developmental stages and the mechanism underlying Cd^2+^‐mediated toxicity are poorly understood. Here, we showed that Cd^2+^ limits plant growth, causes intense redness in leaf vein, leaf yellowing, and chlorosis during the R1 reproductive stage of soybean (Glycine max). These symptoms were associated with Cd^2+^‐induced PCD, as Cd^2+^‐stressed soybean leaves displayed decreased number of nuclei, enhanced cell death, DNA damage, and caspase 1 activity compared to unstressed leaves. Accordingly, Cd^2+^‐induced NRPs, GmNAC81, GmNAC30 and VPE, the DCD/NRP‐mediated cell death signalling components, which execute PCD via caspase 1‐like VPE activity. Furthermore, overexpression of the positive regulator of this cell death signalling GmNAC81 enhanced sensitivity to Cd^2+^ stress and intensified the hallmarks of Cd^2+^‐mediated PCD. GmNAC81 overexpression enhanced Cd^2+^‐induced H~2~O~2~ production, cell death, DNA damage, and caspase‐1‐like VPE expression. Conversely, BiP overexpression negatively regulated the NRPs
