- 摘要:
- 为探讨被子植物性别决定规律,用甜瓜的性别决定机制,对白麦瓶草、酸模、葡萄、蓖麻、西瓜、菠菜、喷瓜、番木瓜和山珠南星等植物的性别决定研究结果进行分析。结果表明:被子植物的性别主要由花器官基因座上的性别决定基因互作控制,具有性染色体的植物只是花器官基因座所在的染色体发生了变异,其性别最终还是由性别决定基因控制。白麦瓶草、葡萄等只有1个花器官基因座的植物,其花型的决定方式,即为该植物的性别决定方式;西瓜、菠菜、酸模、喷瓜、番木瓜等具有2个花器官基因座的植物,其性别由2个花器官基因座上的性别决定基因互作控制;山珠南星和蓖麻等具有3个或多个花器官基因座的植物,其性别由3个或多个花器官基因座上的性别决定基因互作控制。
- Abstract:
- In order to explore sex determination of angiosperm,using the sex-determining mechanism of melon,the research on sex determination about the Silene latifolia,garden sorrel,grape,castor-oil plant,watermelon,spinach,squirting cucumber,papaia papaya and Arisaema yunnanense Buchet were analyzed.The results showed that the sex of angiosperm was controled interoperability by sex determination genes from the floral organ loci though happened the chromosome variation.There was only one floral organ loci to some plants such as the Silene latifolia and grape,etc.The determination way of flower type was their sex determination way.But such as the watermelon,spinach,garden sorrel,etc.there were two floral organ loci in them and their sex were controlled by two sex determination genes interoperability.At the same time,A.yunnanense?Buchet and castor oil plant were controlled by three or more sex determination genes.
