CeO ₂ Nanoparticles Seed Priming Increases Salicylic Acid Level and ROS Scavenging Ability to Improve Rapeseed Salt Tolerance (Global Challenges 7/2022)

Salinity inhibits or delays seed germination. Seed nanopriming is an effective and cost-saving technique to improve crop stress tolerance. In article 2200025 Honghong Wu, Zhaohu Li, and coworkers show that seed priming with polyacrylic acid coated nanoceria improves rapeseed salt tolerance at germination and early seedling growth stages, and associate it with the maintenance of ROS homeostasis and the modulation of hormones level, especially salicylic acid.
