    摘要:

    铁是植物细胞生命过程中必不可少的金属元素之一,参与呼吸作用、叶绿素生物合成、光合作用等生命过程。土壤中含有大量的铁元素,但是有效铁的利用受到限制导致植物缺铁,直接关系到其生长发育和花粉活力及品质形成,进而造成产量损失。解决该问题的重要举措在于如何提高大豆对铁元素的吸收转运和高效利用。因此,掌握大豆铁吸收转运和利用规律并明确其背后的分子遗传机制是实现大豆铁营养高效的重要前提。本文重点阐述了大豆体内铁元素的吸收转运、铁元素参与大豆固氮作用以及缺铁和高铁对大豆的影响等内容,综述了国内外大豆铁元素吸收、转运机制和分子调控机理方面的进展及重要科学问题和方向,旨在为大豆铁营养高效利用提供理论信息。

    Abstract:

    Iron is one of the essential metal elements in the life process of plant cells, which is involved in respiration, chlorophyll biosynthesis, photosynthesis and other life processes. The soil contains a large amount of iron, but the use of available iron is limited, resulting in iron deficiency in plants, which is directly related to their growth and development, pollen viability and quality formation, and thus resulting in yield loss. An important measure to solve this problem is how to improve the absorption and efficient utilization of iron in soybeans. Therefore, mastering the law of soybean iron absorption and utilization and clarifying the molecular genetic mechanism behind it are important prerequisites for achieving efficient utilization of iron in soybean. This article focuses on the absorption and transportation of iron in soybean, the involvement of iron in soybean nitrogen fixation, and the effects of iron deficiency and high iron on soybean. It reviews the progress, important scientific issues, and directions in the absorption, transportation mechanisms, and molecular regulation mechanisms of iron in soybean at home and abroad, aiming to provide theoretical information for the efficient utilization of iron nutrition in soybean.
