摘　　要：伽蓝菜属(Kalanchoe)植物在园艺观赏和传统医药领域具有重要的应用价值,而且为基础理论的研究,特别是在景天科代谢途径和体细胞胚发生的分子机制探讨方面,提供了非常理想的模式系统。遗传转化方法是关系到植物性状定向改良和基因功能研究的核心技术,能极大加速育种进程和机制挖掘。本综述系统讲述了多种伽蓝菜属植物(K. laciniata, K. blossfeldiana, K daigremontiana, K.×houghtonii, K. pinnata, K.fedtschenkoi)的遗传转化方法,并且探讨了这些方法在改造花色、叶型、株型、花期、抗衰老等应用方面以及在景天科代谢途径和细胞命运转变的机理方面的研究进展,以期为进一步开发和利用伽蓝菜属植物提供比较全面的信息资源。Kalanchoe plants play important roles in the fields of ornamental horticulture and traditional medicine,which also provide a very ideal model system for basic theory research, especially on the molecular mechanisms of CAM pathway and somatic embryogenesis. Genetic transformation is the core technology related to directional improvement of plant traits and investigation of gene functions, therefore leading to acceleration of breeding progress and mechanism exploration. This study systematically reviewed the transformation methods of multiple Kalanchoe plants（K. laciniata, K. blossfeldiana, K. daigremontiana, K.×houghtonii, K. pinnata, K. fedtschenkoi）and discussed the research progress of these methods on the application of genetic modification of flower color,leaf morphology, plant architecture, flowering time, anti-aging properties, and on the mechanism of CAM pathway and cell fate transition, so as to provide comprehensive information resources for further exploitation and utilization of Kalanchoe plants.
