植物的性别决定机制

植物性别决定具有不稳定性和多样性的特点,彻底揭示其机制难度较大,目前已经成为基因组学、染色体组学、进化遗传学和发育遗传学的研究热点。本文从性别决定基因、性染色体和激素调控三方面,以模式植物拟南芥(Arabidopsis thaliana L).、白麦瓶草(Silene latifolia L).、玉米(Zea mays L).、黄瓜(Cucumis sativus L.)和番木瓜(Carica papaya L.)等为例,概述植物性别决定机制的国内外研究进展,总结了各学科相关研究主要技术路线、试验方法以及研究中尚待解决的问题,并重点介绍了分子标记、RNA沉默、FISH、SSH、BAC文库等遗传分析技术的应用使本研究领域取得的重大突破。

Sex-determining mechanisms in plants

Nowadays, the plants sex-determining mechanism has become a research focus in the fields of genomics, evolutionary genetics and developmental genetics; however, it is difficult to be illustrated for its insta- bility and diversity. This paper generally introduced the home and abroad study developments of three aspects such as sex-determining genes, sex chromosomes and hormone regulation with the examples of the model plants Arabidopsis thaliana L., Silene latifolia L. Zea mays L. Cucumis sativus L. and Cari...
