摘要

一氧化氮(NO)是具有生物活性的重要信号分子, 在植物生长发育的许多过程中发挥调节作用。越来越多的研究证据表明, NO在植物花发育过程中具有重要作用, 然而迄今尚未见关于NO调控植物花发育方面的系统报道。文章介绍了植物NO合成途径的最新研究进展, 综述了NO抑制植物开花转换可能的作用机理和NO在花粉萌发与花粉管延伸过程中的调节作用, 以期为植物内源NO的生物合成及NO对花发育的调节研究提供参考。

Abstract

Nitric oxide (NO) is an essential signaling molecule, which is involved in many aspects of plant growth and development. There is increasing evidence that NO plays a vital role in the process of flower development, which, however, has not been comprehensively reviewed for a long time. In this review, we provide an overview of the multiplicity of NO production in plants, and discuss the potential repression mechanism of NO in flower transition and the role of NO in pollen germination and pollen tube elongation.
