| 摘 要： | 雌蕊由心皮和花柱组成并最终发育成果实,其发育对作物的产量、质量都有决定性的影响。因此,对雌蕊败育相关基因的研究是植物生物学研究领域的热点,KNOX家族是植物中的5个同源异型盒基因家族之一,分为Ⅰ类和Ⅱ类KNOX亚家族,主要在植物茎顶端分生组织中特异表达,是分生组织发生与维持所必需的关键基因,调控与器官发生相关的细胞分化,最终影响侧生器官的形态建成、该文综述了与雌蕊发育相关的KNOX家族基因功能,重点对KNOX家族中的KNOX Ⅰ类基因进行了阐述。

| Abstract: | The pistil is composed of the carpel and style and eventually develops into a fruit,which contributes to the crop yield and quality.Therefore,female development is a hot spot in the research field of plant biology.KNOX genes,one of the five homeobox gene families in plant,can be divided into subclasses Class-Ⅰ and Class-Ⅱ,characteristically expressed in the shoot apical meristem of plant,which are essential for meristem initiation and maintenance by controlling cell division,ultimately influencing the morphogenesis of lateral organ,In this paper,the known functions of some genes are summarized related to the pistil development,especially focusing on the class-Ⅰ genes of KNOX families. |
