摘　　要：Biofortification of staple crops through genetic modification is a sustainable way to overcome nutrient deficiencies worldwide,especially in low-income developing countries.Iron is one of the most important minerals required for the human body and participates in crucial physiological processes including oxygen transport,electron transport for energy production,and so on.While there are some reports of genetically engineered crops with increased iron content,such as rice,wheat,and cassava,iron biofortification of maize has been challenging due to the trade-off between kernel iron concentration and maize yield(Long et al.,2004).In a recent article published in Science,researchers used molecular-marker-assisted selection to eliminate this trade-off and developed maize varieties with increased iron concentration in kernels without compromising yield(Yan et al.,2023).
