| 摘 要： | 提高矿物质营养元素含量正在成为世界主要粮食作物的重要研究方向和育种目标。钙元素是人体必需的矿物质元素,在人类骨骼形成和新陈代谢中发挥着重要作用。全球约35亿人缺钙,缺钙已成为影响人类健康的国际性重大问题。主食是一种最优安全的矿物质元素补充途径。小麦是我国乃至全世界主要粮食作物,是全球35%~40%人口主要的食物来源,是摄入钙的主要来源,是矿物质元素生物强化的重要作物。通过遗传改良方法提高小麦籽粒钙元素含量被认为是解决缺钙最经济、有效、可持续的措施,目前已引起了国内外学者的高度关注。本文综述了近年来小麦籽粒钙元素含量的研究进展,主要包括籽粒钙含量的遗传差异、影响因素以及与相关性状关系、调控机理。此外,我们还提出了将来进行钙营养强化小麦研究的方向,此研究内容为加快通过主粮实现有效补钙、倡导健康营养的膳食模式、满足由“量”的需求向“质”的需求转变的粮食安全、改善国民健康状况以及减少因缺钙造成的经济损失提供了解决方案。

| Abstract: | Increasing the mineral content is becoming the important research direction and major target for crops breeding in the world.Calcium is an essential mineral element for human health and plays a pivotal role in skeletogenesis and metabolism.It is estimated that about 3.5 billion people was suffered from calcium deficiencies.Calcium deficiency has become a major international problem harming human health.The staple food is an optimal and safe way to mineral supplement.Wheat,one of the main food crops in China and even in the world,is the main source of food for 35%–40%of global population,a main source for human’s calcium intake as well as an important crop of mineral element biofortification.Improving the calcium content in wheat grains through genetic improvement is considered to be the most economical,effective and sustainable measure to solve the calcium deficiency,which has aroused great concern from international scholars.This paper summarized the recent advances in the study of calcium content in wheat grains,mainly including the genetic variation,affecting factors,the relationship with related traits and regulation mechanism of calcium content in grain.Furthermore,we also put forward the direction of future research on calcium-fortified wheat,which provides solutions for accelerating the effective calcium supplementation through staple food,promoting the healthy and nutritious dietary pattern,ensuring the food security to meet the transition from“quantitative”to“qualitative”demands,improving people’s health,and reducing economic losses caused by calcium deficiency. |
