摘要
在果树生长发育所必需的微量元素中,铁(Fe)的需求量最大,铁元素参与果树生长过程中的众多生化途径和代谢反应。然而,土壤中的铁多为三价铁,并以铁螯合物形式存在,植物根际对其利用微乎其微。目前,研究植物铁吸收、转运和分配的分子机制是各领域的热点内容,对其关键基因的研究大多集中在拟南芥、番茄等模式植物中,在果树上的研究极其稀缺。因此,本文通过综述国内外对关键基因的克隆和功能分析,以期进一步明确果树作物铁吸收、转运与分配的分子机制,为解决多年生果树缺铁或挖掘铁高效利用种质资源提供理论依据。
Among the trace elements necessary for fruit growth and development,iron(Fe)is the most needed element,which participates in many biochemical pathways and metabolic reactions during fruit growth and development.However,iron in soil is mostly trivalent and exists in the form of iron chelate,and the utilization of iron in plant rhizosphere is very little.At present,the research on the inolecular mechanism of iron uptake,transport and distribution in plants is a hot topic in various fields.Most of the studies on key genes are focused on Arabiclopsis thaliana,tomato and other model plants,but largely rare on fruit trees.Therefore,the molecular mechanism of iron absorption,transportation and distribution in fruit crops could be further clarified by summarizing the cloning and functional analysis of key genes at home and abroad,so as to provide theoretical basis for solving iron deficiency in fmit crops or mining iron efficient utilization gemiplasm resources.
