neral levels have been developed using the tools of genetic modification, but non-grass plants such as cassava take up minerals from the soil in a different way.
Ultimately it was a combination of two genes, IRT1 and FER1, from the model plant species Arabidopisis that led to cassava plants with iron concentration levels 6-12 times higher than conventional cassava and zinc concentrations that were 3-10 times higher. It was a real challenge to find a combination of genes that would raise both ir
