摘要: 兰科Orchidaceae植物具有唇瓣、蕊柱等独特花形结构。近年来,关于兰科植物开花调控的研究取得了一定的进展,已分离鉴定出一些花发育调控基因,包括花器官特异基因及一些花分生组织特异基因。研究表明: MADS-box等基因在兰花的成花转换及花器官形成过程中起重要作用,特别是B类基因的表达及功能可能与兰花结构的特异性及多样性有关。表1参33

Abstract: Orchidaceae have unique floral morphology and structure including gynostemium and Labellum. Recently,some homologous floral organ identity genes and meristem identity genes have been identified and separated from different orchids. These researches indicated that the homologous MADS-box genes played important roles in the flowering transition and the floral morphogenesis of orchids. Especially,the B-function genes might regulate the development of the floral perianth. This review summarized the recent progresses on the flowering control in orchids. [Ch,1 tab. 33 ref.]-
