GmFER1, a soybean ferritin, enhances tolerance to salt stress and root rot disease and improves soybean yield.

ABSTRACT: The plant stress response mechanism is activated by biotic and abiotic stresses, but its continuous activation typically affects growth. The role of ferritin in regulating biomass accumulation has been extensively characterized in diverse plant species; however, the underlying mechanisms through which it contributes to salt stress tolerance and Fusarium resistance remain poorly understood. Here, we confirm that overexpression of ferritin leads to iron accumulation and Fe³⁺ sequestration in both aboveground and roots, activating the iron uptake and transport system. More importantly, GmFER1 enhances salt stress tolerance and Fusarium resistance. First, GmFER1 is localized in chloroplasts and significantly induced by salt stress and Fusarium infection.
