Abstract

Arbuscular mycorrhizas support nutrient uptake from the soil. Here we demonstrated Iron-59 (59Fe) uptake in maize (Zea mays L.) through the mycorrhizal roots. Arbuscular mycorrhizal colonization did not strongly induce Strategy II-related genes, but the putative iron transporter genes, OPT8a and OPT8b, were induced by more than 50-fold. Our data provide a previously undescribed gene expression mode related to the iron uptake system of Strategy II plants.
