摘要
在开花植物中,存在着两性花植物、雌雄单性同株及雌雄单性异株植物等多种性别形态的植物种类,这就是植物的性多态现象。单性花的发生是由于原两性花原基的雌蕊或雄蕊选择性败育所造成的。由于单性花仅含有一种有功能的性器官,因此它便成为研究性别决定分子机理的良好对象。本文阐述了高等植物单性花形成中,性别决定的遗传机理。
Of all the flowering plants, there exist many kinds of plants which have different sexual statement, such as hermphrodite, dioecy, monoecy etc. That is called the sexual polymorphism. The unisexual flower is caused by the selective abortion of androecium or gynoecium in the hermphroditic primondia. Since the unisexual flower only has a kind of functional sexual organ, it has been the good material in molecular mechanism research of sex determination. This article provides the explanation of the hereditary mechanism in the formation fo unisexual flower.
