摘要 发展中国家及偏远地区人们普遍侧重植物性食物。植物类食物含铁量偏低,容易导致人体产生各种缺铁病症。缺铁病症尤其是缺铁性贫血严重影响着育龄妇女和儿童的身体健康。虽然铁在土壤中含量丰富,但生物有效性低。目前缺铁是与缺氮和缺磷并列的、发生最为广泛、对植物生长发育影响最大的限制因子之一。因此,改善植物的铁营养成为了当今土壤和植物营养学研究热点。通过综述近年来机理Ⅰ植物根系形态变化、铁吸收过程、应答缺铁胁迫调节网络及缺铁胁迫感应信号研究进展,为通过分子生物学手段解决植物缺铁问题提供理论依据。 People in developing countries and remote areas generally focused on plant‐based foods ,whose iron content was low ,and easily resulting in all kinds of iron deficiency disorders of human body .Iron deficiency symptoms especially iron‐deficiency anemia severely affects women of childbearing age and children's health . The soil was much rich in iron ,but the biological effectiveness was very low .The iron deficiency ,as nitrogen deficiency and phosphorus deficiency ,one of the most widely and seriously limiting factors of plant growth and development .Therefore ,how to improve the plant iron nutrition is becoming a research focus in soil science and Plant nutrition .An overview of the strategy Ⅰ plant root morphology change ,iron acquisition process ,adjust‐ment network and induction signal of iron deficiency was provided ,so as to provide the theory basis for solving the problem of plant iron deficiency by means of molecular biology .
