Overexpression of OsFH2 enhances cadmium tolerance and reduces grain cadmium accumulation in rice through synergistic root sequestration and antioxidant defense activation

Key Points

• Enhancing osfh2 expression significantly reduces grain cadmium accumulation and improves cadmium tolerance in rice plants.
• A key metric shows a more than 50% reduction in cadmium levels in grains when osfh2 is overexpressed.
• Analysis reveals synergistic root sequestration and boosted antioxidant defense mechanisms as underlying approaches.
• These findings highlight potential strategies for improving grain safety and crop resilience against soil contaminants.
