目前,铁、锌元素营养失衡已严重影响人类健康,而小麦(Triticum aestivum L.)作为人们主要的食物,其子粒中铁、锌元素含量普遍较低。因此,通过小麦育种策略提高铁、锌元素含量则被认为是最经济有效的手段,这也引起了国内外学者的广泛关注。本文概述了小麦子粒铁、锌元素含量的遗传差异、影响因素以及分子机理的研究现状,并展望了提高小麦子粒铁、锌元素含量的研究前景及途径。
Malnutrion of iron(Fe)and zinc (Zn) minerals has been one of the most essential causes of harm to human health.Wheat (Triticum aestivum L.) is one of the important staple crops as the resources of both foods and minerals. However, low content of Fe and Zn in wheat grains has caused great concerns to international scientists. Breeding of new wheat cultivars, which are rich in mineral content, is regarded as the most economical and sustainable approach to overcome mineral malnutrition. In this paper, current researches on the genetic difference, influence factors and the molecular mechanism of micronutrient enrichment were reviewed. Additionally,the perspective of research on wheat Fe and Zn quality was outlined.
