Amino acid transporters are the main mediators of nitrogen distribution throughout the plant body, and are essential for sustaining growth and development. In this review, we summarize the current state of knowledge on the identity and biological functions of amino acid transporters in plants, and discuss the regulation of amino acid transporters in response to environmental stimuli. We focus on transporter function in amino acid assimilation and phloem loading and unloading, as well as on the molecular identity of amino acid exporters. Moreover, we discuss the effects of amino acid transport on carbon assimilation, as well as their cross-regulation, which is at the heart of sustainable agricultural production.

植物中的氨基酸转运蛋白：鉴定和功能。

氨基酸转运蛋白是氮素在植物体内分布的主要媒介，对于维持生长和发育至关重要。在这篇综述中，我们总结了植物中氨基酸转运蛋白的身份和生物学功能的当前知识状态，并讨论了氨基酸转运蛋白对环境刺激的调节作用。我们专注于氨基酸同化和韧皮部加载和卸载中的转运蛋白功能，以及氨基酸输出蛋白的分子身份。此外，我们讨论了氨基酸转运对碳同化的影响及其交叉调控，这是可持续农业生产的核心。
