甜菜碱对植物重金属胁迫抗性影响的研究进展
|
摘要
土壤重金属污染导致的农作物重金属累积会提高食用人群的健康风险,故近年来甜菜碱对植物重金属胁迫抗性的研究引起关注。具体介绍了甜菜碱对植物重金属胁迫抗性影响的最新研究进展,并重点综述了其影响机制:甜菜碱可通过增加根际土壤溶液中低分子有机酸﹑有机碳和可溶性糖的量促进植物对重金属的吸收,还可通过影响钙﹑铁等无机离子的吸收转移和增加叶片中果胶﹑叶绿素含量来促进重金属在叶片的累积,提高植物对重金属胁迫的抗性,最后指出需关注的研究方向。
The accumulation of crop heavy metals caused by soil heavy metal pollution can increase the health risk of the food users. Therefore, in recent years, the study on the resistance of betaine to plant heavy metal stress has attracted attention. This paper introduces the latest research progress of the effects of betaine on plant heavy metal stress resistance, and focuses on its functional mechanism: through increasing the contents of LMWOAs, DOC and soluble sugar in the rhizosphere soil solution, glycinebetaine enhanced the absorption of heavy metals by plants. In addition, through affecting the absorption and transfer of inorganic ions such as Ca, Fe and increasing the chlorophyll and pectin contents in the leaves, glycinebetaine promoted the accumulation of heavy metals in leaves, such that the resistance to heavy metal stress was improved. Finally, the research directions that need to be paid close attention to is pointed out.
