兰花花发育的分子生物学研究

Progress on Molecular Biology of Orchid Floral Development

兰花是显花植物中最大的家族之一,广泛分布于各种生态环境中,表现出高度特异的形态、结构和生理特性。它与多数开花植物不同,其子房的发育是由授粉启动的,即先授粉,后发育,这也是兰科植物的特殊性所在;兰花的花期之长也与大多数开花植物不同,这可能与兰花特殊的结构和发育过程相吻合。因此,兰花是研究花器官发育的理想材料。本文就近年来在这方面研究取得的进展、存在的问题及展望进行了综述。

Orchids are members of the Orchidaceae family,one of the largest families of flowering plants.Orchids have highly specialized morphological,structural and physiological characteristics,which makes them have the distinct advantages of studying floral development.The advances in the research on molecular biology of orchids floral development are reviewed in this paper.The limitation in the research was analyzed,the suggestion on the future research work was proposed and the further development on molecular biology of orchids was promising.
