| 摘 要： | 作为植物中普遍存在的一种逆境适应机制,脯氨酸积累一直被认为是其合成和降解调控的结果。然而越来越多的研究表明,脯氨酸转运也可能在其积累过程中起重要作用。在植物中,有多个氨基酸转运蛋白家族,如氨基酸通透酶家族(AAPs)、赖氨酸组氨酸转运蛋白家族(LHTs)和脯氨酸转运蛋白家族(ProTs)参与脯氨酸在各个器官间的运输。该文对参与脯氨酸运输的基因家族成员的表达模式、生理功能及表达调控进行了综述,以期为脯氨酸运输与积累在植物抗逆方面的研究提供参考。 |

| Abstract: | As a wide-spread stress adaption in plants, proline accumulation is thought to result from increased biosynthesis and decreased degradation. However, accumulating reports showed that proline transport also plays a role in stress-induced proline accumulation. In plants, several amino acid transporter protein families, such as AAPs, LHTs and ProTs, can transport proline. In this review, we summarize the expression pattern, function and expression regulation of these families in terms of proline transport, with an aim to provide some useful information on proline transport and accumulation research in plants. |
| Keywords: | proline proline transport amino acid transporter protein expression regulation |
