机理Ⅰ植物铁吸收与运输的分子机制

Molecular biological mechanism of iron uptake and translocation in strategy Ⅰ plant

  • 摘要: 铁虽然在地壳中的含量很高,但生物有效性非常低,植物如何适应缺铁胁迫一直是植物营养与植物逆境生理领域研究的热点问题。近两年来,人们对于植物,尤其是机理Ⅰ植物适应铁胁迫的机制又有了新的认识,铁还原酶基因的表达部位除根系外,在地上部、花等器官也能够检测到;IRT1基因是机理Ⅰ植物主要的Fe(Ⅱ)运输基因;烟碱酰胺在铁的长距离运输中起到重要作用。本文从还原、吸收、长距离运输及对这些过程的调控等方面综述了近年来有关机理Ⅰ植物适应铁胁迫的研究进展,并对将来的研究方向进行了初步展望。

     

    Abstract: Plant iron deficiency is a problem due to its low availability in soil.Plant has developed two strategies to secure iron uptake named strategy Ⅰ and strategy Ⅱ,respectively.Strategy Ⅰ plants include higher plants except the gramineae,while strategy Ⅱ is mainly refers to gramineae.In the last two years, the research on the mechanisms of iron uptake and translocation in strategy Ⅰ has been made a great progress: FRO expresses not only in root but also in shoot and flower;IRT1 is the main Fe(Ⅱ) transporter in strategy Ⅰ plants;NA plays an important role in long distance translocation of iron.This article presents recent progress on iron uptake and translocation in the strategy Ⅰ plant.
