植物中游离氨基酸在水淹胁迫下响应的研究进展

摘要

游离氨基酸含量的变化可以用来指示环境压力的变化.近年来,研究植物形态、分布格局等对水淹的响应较多,但对植物中氨基酸代谢机制的研究较少.综述水淹下植物中氨基酸代谢的变化,主要包括植物组织中游离氨基酸GABA、Glu在水淹胁迫下的响应,以及植物中其他游离氨基酸的响应情况,提出以后研究应关注复合压力胁迫下植物中游离氨基酸的响应.%Changes in free amino acids content can be used to indicate changes in environmental stress.Very little attention has been paid towards the response of free amino acids mechanism in plants to the flooding stress compared to morphology and distribution pattern.Amino acid mechanism to response to flooding stress was reviewed,not only the response of free amino acids GABA and Glu under plant flooding,but also the responses of other free amino acids in plants.Response of free amino acids in plants to composite environmental stress should be focused in future research.
