同源多倍体化对植物侧生器官形态建成影响的研究进展

Research Progress on Effect of Autopolyploid on Plant Lateral Organ Morphogenesis

同源多倍体化过程可以产生不同倍性的整倍体或非整倍体,其植株在侧生器官形态建成上可表现出规律性的变化,且同源多倍体化后植株定殖能力和远源杂交能力增强。系统阐述了整倍体化对叶片、花萼、花瓣等侧生器官形态建成的影响及非整倍体化对植物侧生器官形态建成的影响,为今后通过同源多倍体化改良作物性状提供理论依据。

During the forming process of autopolyploid,different ploidy of euploid or aneuploid can be produced.The morphogenesis of lateral organs of plants can show regular changes,and the colonization ability and distant hybridization ability of plants are enhanced after autopolyploid formed.The effects of euploidy on the morphogenesis of lateral organs such as leaves,calyx and petals and the effects of aneuploidy on the morphogenesis of lateral organs were systematically expounded,so as to provide theoretical basis for the improvement of crop traits through autopolyploid in the future.
