植物氨基酸转运蛋白的研究进展

Research Progress of Amino Acid Transporters in Plants

氨基酸对植物的生长与发育必不可少,氨基酸转运蛋白在植物体内各种氨基酸的转运过程中发挥极其重要的作用。目前已经鉴定了多种氨基酸转运蛋白,并且许多重要的植物基因组序列已经完成了拼接和组装工作,但人们对氨基酸转运蛋白的功能与调节还知之甚少。本文综述了植物氨基酸转运蛋白的进化、表达、功能及调控方面的新进展,以期为主要粮食作物的遗传改良提供借鉴与参考。

Amino acid transporters have essential roles in the transport of a broad range of amino acids, which are indispensable in plant growth and development. While many putative amino acid transporters have been identified and the complete genomic sequences of the important plants have already been completed by splicing and assembling, there is still little known about the regulation of amino acid transporter function. This study mainly reviewed the evolution, expression, function and regulation of amino acid transporters in plants. This review would provide useful references for staple food crops in plants.
