2000 years of agriculture in the Atacama desert lead to changes in the distribution and concentration of iron in maize

Abstract We performed a histological and quantitative study of iron in archaeological maize seeds from prehispanic times recovered from Tarapacá, Atacama Desert. Also, we examined iron distribution changes at the cell level in embryos from ancient versus new varieties of maize. Our results show a pr...
