摘　　要：多胺是一类广泛存在于生物体内的小分子含氮碱,参与了植物生长发育的整个过程,并与抗逆性密切相关。目前,植物中的多胺合成代谢途径已基本揭示,多个代谢途径中编码相关酶的基因也已克隆。本文综述了植物多胺代谢途径的异同点及演化过程,重点阐述了多胺的生理功能、多胺与激素的关系以及多胺在抗性中的作用,希望给未来的生物合成和基因组育种提供帮助。Polyamines are a class of low molecular weight aliphatic cations with strong biological activities found in a wide variety of prokaryotic and eukaryotic organisms.Polyamines are associate with the whole process of plant growth and development and play important role in stress resistance.At present,the synthesis and metabolism of polyamine have been basically uncovered,and genes encoding related enzymes in multiple metabolic pathways have also been cloned.This paper reviews the similarities and differences of plant polyamine metabolic pathways,highlights the physiological functions of each gene in this pathway,and hopes to provide assistance for future biosynthesis and genome breeding.
