Genotype-adaptive regulatory mechanisms of nano-silicon in alleviating cadmium toxicity in pakchoi

Key Points

• Cadmium toxicity is alleviated by nano-silicon in both Cd-tolerant and Cd-sensitive pakchoi cultivars, favorably impacting plant health.
• Under 10 μM cadmium stress, nano-silicon demonstrated superior protective effects compared to ionic silicon in tested pakchoi varieties.
• The approach involved a comparative assessment of packaging, facilitating insights into genotype-specific regulatory mechanisms of silicon.
• Findings suggest broader implications for agricultural management strategies in cadmium-polluted environments.
