The non-proteinogenic amino acid nicotianamine (NA)chelates and transports essential metal ions in plants. The enhancing effect of NA on the bioavailability of metals makes it appealing for biofortification approaches. The goal of this project was the localization of NA activity and the elucidation of a concrete function of NA in Fe and Cu translocation throughout the plant using the model plant Arabidopsis thaliana. Arabidopsis has four NICOTIANAMINE SYNTHASE (NAS) genes. To investigate NA function two quadruple nas mutants, named nas4x-1 and nas4x-2 were analyzed to study NA function in Arabidopsis: nas4x-2 had a full loss of NAS function, was sterile, and suffered from severe chlorosis in young leaves. nas4x-1 had residual NA contents, ...
