在水稻育种实践中，培育富含必需微量营养素并同时降低籽粒中有毒元素水平的水稻品种在很大程度上尚未得到探索。Liu et al.（2020）在本期《生物多样性杂志》上培育了两种镉含量低、锌或硒含量高的水稻品系，为培育解决矿物质营养不良和确保食品安全的水稻品种提供了优质遗传材料。
Breeding of rice varieties that are enriched with essential micronutrients and simultaneously have reduced levels of toxic elements in grains is largely unexplored in rice breeding practice. In this issue of JIPB, Liu et al. (2020) developed two rice lines with a low level of cadmium and simultaneously high levels of zinc or selenium accumulation in the grains, thus providing elite genetic materials for breeding rice varieties that are important for addressing mineral malnutrition and ensuring food safety.
