    Nanhu News Network (Correspondent Li Yanhui) Recently, following the report on the mechanism of cerium oxide nanoparticles improving the salt tolerance of cotton (Liu et al.


    Salt stress is one of the main limiting factors affecting the efficient production of crops


    Cerium oxide nanoparticle seed priming improves the sodium and potassium homeostasis of rape seedlings

    In this study, the researchers synthesized polyacrylic acid modified cerium oxide nanoparticles (PNC) with a low Ce3+/Ce4+ doping ratio


    Alpha-amylase is a key enzyme responsible for starch degradation during seed germination


    The distribution of cerium oxide nanoparticles in rape seeds during seed initiation

    Mohammad Nauman Khan, a postdoctoral fellow in the research group of Professor Wu Honghong from the School of Plant Science and Technology of our school, is the first author of the paper, and Professor Li Zhaohu and Professor Wu Honghong from the School of Plant Science and Technology are the corresponding authors

    【English summary】

    Background

    Salinity is a big threat to agriculture by limiting crop production.


    Results

    Herein, we used cerium oxide nanoparticles (nanoceria) to prime rapeseeds and investigated the possible mechanisms behind nanoceria improved rapeseed salt tolerance.


    Conclusions

    Our results suggested that besides the more absorbed water and higher α-amylase activities, PNC nanopriming improves salt tolerance in rapeseeds through alleviating oxidative damage and maintaining Na+/K+ ratio.
