Constitutive expression of a barley Fe phytosiderophore transporter increases alkaline soil tolerance and results in iron partitioning between vegetative and storage tissues under stress

► We engineered rice and regenerate transgenic plants expressing the HvYS1 transporter. ► Transgenic rice exhibited enhanced tolerance to alkaline soil conditions. ► Transgenic rice absorbed iron more efficiently than wild type. ► Transgenic rice diverts additional iron to leaves over seeds.
