Environmental significance

We investigated the physiological and molecular response of cucumber plants to a Cu(OH)2 nanopesticide. We demonstrated that foliar exposure to the nanopesticide increases the expression levels of several key antioxidant and detoxification related genes (SOD, GPX4, GPX, MDAR, POD, and WRKY6). This indicates that the Cu(OH)2 nanopesticide induces oxidative stress and activates the antioxidant defense system in the plants. Exposure to Cu2+ from CuSO4 also increased the transcript production of the SOD, GPX4, GPX, MDAR, POD, and WRKY6 genes, and also increased transcription of WRKY30, GST, CAT, APX and GPX2 genes. In addition, Cu2+ activated two regulatory genes (RBOH and MAP3K3), which was not observed in plants treated with Cu(OH)2 nanopesticide. The up-regulation of the expression levels of those genes are a protective mechanism for cucumber plants. These results provide a deeper understanding of the antioxidant defense responses in plants exposed to Cu(OH)2 nanopesticides and may be applicable to other plant/nanopesticide interactions.
