Over three billion people suffer from various health issues due to the low supply of zinc (Zn) and iron (Fe) in their food. Low supply of micronutrients is the main cause of malnutrition and biofortification could help to solve this issue. Understanding the molecular mechanisms of biofortification is challenging. The membrane transporters are involved in the uptake, transport, storage, and redistribution of Zn and Fe in plants. These transporters are also involved in biofortification and help to load the Zn and Fe into the endosperm of the seeds. Very little knowledge is available on the role and functions of membrane transporters involved in seed biofortification. Understanding the mechanism and role of membrane transporters could be helpful to improve biofortification. In this review, we provide the details on membrane transporters involved in the uptake, transport, storage, and redistribution of Zn and Fe. We also discuss available information on transporters involved in seed biofortification. This review will help plant breeders and molecular biologists understand the importance and implications of membrane transporters for seed biofortification.
超过30亿人因食物中锌（Zn）和铁（Fe）供应不足而患有各种健康问题。微量营养素供应不足是营养不良的主要原因，生物强化有助于解决这个问题。了解生物强化的分子机制具有挑战性。膜转运蛋白参与植物中锌和铁的吸收、运输、储存和再分配。这些转运蛋白也参与生物强化，并有助于将锌和铁装载到种子的胚乳中。关于参与种子生物强化的膜转运蛋白的作用和功能，人们了解得很少。了解膜转运蛋白的机制和作用可能有助于改善生物强化。在这篇综述中，我们详细介绍了参与锌和铁吸收、运输、储存和再分配的膜转运蛋白。我们还讨论了参与种子生物强化的转运蛋白的现有信息。这篇综述将帮助植物育种者和分子生物学家了解膜转运蛋白对种子生物强化的重要性和影响。
