Plants do not live in isolation but in close interaction with associated microorganisms that play an important role in plant nutrition and tolerance to biotic and abiotic stresses. We are interested in studying how legume endosymbionts (Rhizobium and arbuscular mycorrhizal fungi) affect plant metal homeostasis. This is important because: i) Iron, zinc and other transition metals are key components of 30-50% of the proteins of a typical cell and are involved in every biological process, ii) there is very little metal bioavailability in most soil types and this results in reduced agricultural output and human and animal malnutrition, and iii) plant endosymbionts act as sources or sinks of these essential oligonutrients.
