摘要
氨基酸是高等植物氮素同化产物长距离运输及在组织间分配的主要形式,通过跨膜转运的方式在植物体内进行运输。氨基酸转运子是位于生物膜上吸收及转运氨基酸的蛋白家族,对植物氮素营养具有重要贡献。本文对植物氨基酸转运子的表达、调控及其与氮素利用效率、植物产量与品质形成、抗逆性及适应性等方面的研究进展进行了综述。
Amino acids are the principal form of organic nitrogen transportation within plants.Amino acid transporters are essential for the import and export of amino acids from plant cells as well as between organelles across cellular or subcellular membranes. Various molecular mechanisms for the absorption and transportation of amino acids have been demonstrated in plants,which contribute significantly to nitrogen efficiency. This review summarizes research progress on the molecular mechanisms of amino acid transporters based on their expression pattern,function,and regulation,which are associated with important traits,such as nitrogen utilization efficiency,disease resistance,quality,and production.
