Diversity in the genome of <i>Aegilops tauschii</i>, a wild wheat relative, to generate Fe-biofortified and Fe-deficiency-tolerant wheat

Abstract Iron (Fe) is an essential element for all organisms. Fe deficiency can limit plant production and cause anaemia in humans. The improvement of homoeostasis could resolve both problems. Aegilops tauschii , the D genome donor bread wheat, not fully understood. Here, we analysed physiological traits 42 accessions Ae. associated with homoeostasis, i.e. mugineic acid family phytosiderophores (MAs), phenylamides, SPAD values metal concentrations. All showed diversity, suggesting presence candidate genes accessions, which improve wheat. mainly produced secreted 2′-deoxymugineic among MAs, but eight them unknown products from their roots under deficiency. It was revealed that 15 kinds phenylamides 2 wheat phytoalexins were Fe-deficient . Multivariate principal component analyses chlorophyll content correlated shoot concentration. Genome-wide association study analysis several genomic markers variations each trait analysed. Our results suggest has alleles to generate Fe-deficiency-tolerant or Fe-biofortified
