多胺及其转运体在杂草对百草枯抗性机制中的作用研究进展

Research progress on the role of polyamines and their transporters in paraquat resistance in weeds

摘要: 通过对多胺在植物体内的形态分布、转运、代谢及其参与植物生长发育和胁迫反应的作用机制,以及杂草对百草枯的抗性机制最新研究进展进行综述,重点围绕多胺对百草枯毒性的缓解作用及多胺转运体在杂草对百草枯抗性机制中的作用进行评述,揭示了多胺及其转运体将是杂草对百草枯抗性机制研究的重要领域。

Abstract: The forms,transportation and metabolism of polyamines,as well as the roles of polyamines in plant were reviewed,and the latest paraquat resistance mechanism in weed was summarized.Much discussion was focus on the alleviation of the paraquat toxicity by polyamines and the important role of polyamines transporter plays in the weed resistance to paraquat.Polyamines and their transporters may be one important area in the study of paraquat resistance mechanism.
