Abstract excerpt
Uranium (U) is a naturally occurring radionuclide that is toxic to plants. It is known to interfere with phosphate nutrition and to modify the expression of iron (Fe)-responsive genes. The transporters involved in the uptake of U from the environment are unknown. Here, we addressed whether IRT1, a high-affinity Fe2+ transporter, could contribute to U uptake in Arabidopsis thaliana. An irt1 null mutant was grown...
