高等植物体内多胺的生理功能及其分子生物学研究进展

Reviews of the Physiological Roles and Molecular Biology of Polyamines in Higher Plants

多胺作为新一类植物生理活动物质与植物生理活动关系密切,如参与各种生理胁迫反应、参与植物衰老进程的调控、花芽分化、胚胎发育等。本文概述了高等植物体内多胺的分子生物学代谢途径,重点综述了多胺在高等植物中生理学功能和分子生物学方面的研究进展,并对有关问题进行了讨论和展望。

Polyamines play multi-physiological roles in plant growth and development. Regulation of plant senescence, floral initiation and development fruit development and a lot of physiological responses to stress are involved in the reviews. On the basis of the brief reviews on the catabolism pathway of polyamine degradation in higher plants, emphases were placed on the advances of the physiological roles＂ and molecular biology of polyamine in higher plants.
