Molecular mechanism of orchid-specific floral organogenesis by a transgenic approach.

为了解兰花唇部、花柱、花粉等特异花器官的分子机制，从石斛（Dendrobium）、蝴蝶兰（Habenaria）和蝴蝶兰（Phalaenopsis orchids）中分离出花器官识别基因。结果表明，B类基因的表达模式与被片的不同形态有关。此外，为了了解花器官鉴定基因的功能，我们构建了转基因蝴蝶兰。

In order to understand the molecular mechanism of the orchid-specific floral organs such as lip, column, pollinium, we isolated floral organ identity genes from Dendrobium, Habenaria and Phalaenopsis orchids. The results indicated that expression pattern of class B genes were related to the various morphology of the tepals. Also, to understand the function of the floral organ identity genes, we constructed the transgenic Phalaenopsis.
