植物中多胺的合成代谢及其分子生物学水平研究进展

多胺广泛存在于动植物体内，具有促进植物生长发育和延缓果实后熟进程等作用，但对其研究大多停留在生理水平，还需从分子生物学水平深入了解其调控机理以及代谢中各通路之间的相互作用关系。本文介绍了多胺生物合成与分解代谢过程，阐述了多胺及其代谢产物的生理功能，同时以国内外研究文献为基础，探讨植物中多胺代谢相关基因的分子生物学作用，指出了目前存在的问题，并为其研究方向提供了建议。

Research Progress on Synthesis Metabolism and Molecular Biology of Polyamines in Plants

Polyamine widely exists in plants and animals, playing a role in promoting plant growth and development and delaying the process of fruit ripening. However, most of researches stay in the physiological level, it is also necessary to understand the mechanism of regulation and the interaction between the pathways in mechanism from the perspective of molecular biology. In this paper, the biosynthesis and catabolism processes of polyamine are introduced, the physiological functions of polyamines and their metabolites are elaborated, at the same time, based on domestic and foreign research literatures, the molecular biological functions of genes related to polyamine metabolism in plants are explored, the existing problems are pointed out and suggestions for the research direction are provided.
