Sulfur mitigates nickel phytotoxicity in Brassica campestris L. via enhanced antioxidant defense and nickel chelation and compartmentalization

Key Points

• Sulfur mitigates phytotoxicity caused by nickel in Brassica campestris, enhancing plant health.
• The treatment led to significant increases in antioxidant defense mechanisms and nickel chelation.
• Analysis using nutrient assays demonstrated improved compartmentalization of nickel within plant tissues.
• These findings highlight sulfur's potential role in enhancing plant resilience against heavy metal stress.
