Due to climate change and population growth, consuming foods with good nutritional quality is necessary to avoid diseases such as anemia. Among the alternatives to combat amenia, selecting species with food potential is one of the most sustainable alternatives, tarwi being an excellent option. Despite growing in marginal soils, this species has a high concentration of iron in seeds, which would indicate that it has an efficient mechanism of absorption, transport, and storage of this mineral is critical for generating biofortified cultivars at low cost, being the purpose of this thesis. First, six accessions with appropriate concentrations of Fe, Zn, B, Cu and Mn for a healthy diet without affecting the physical characteristics of the seeds were identified: T05, T08, T25, P14, P16 and P21. Then, using bioinformatics tools, 16 proteins associated with iron absorption, transport and storage were identified and functionally characterized. Finally, gene expression changes of the corresponding proteins analyzed in silico were evaluated with the accession T25 and the cultivar Andenes (control), revealing that the genes AHA2, FER2, NAS1, YSL1, NRAMP1, NRAMP3, VIT1 and TC21 are critical for improving adaptability and iron concentrations at the seed level in tarwi due to their high expression under iron deficiency.
