植物发育中的位置信息

Positional information in plant development

位置信息是植物发育的重要机制之一,细胞的位置信息在植物模式建成中具有中心地位,是决定植物细胞分化的主要因素之一。文章从位置信息概念入手,通过位置信息与细胞壁、生长素关系的讨论,对位置信息的作用机制进行了阐述,并对位置信息与植物发育过程中其他细胞信息的关系进行了简单介绍。

Abstract： Positional information is one of the important mechanisms underlying plant development because it is in the centre position of plant pattern formation, and it is one of the most important factors in plant cell differentiation. This paper started with the definition of positional information, expounded the mechanism of it according to the relationship between positional information and cell wall and the relationship between positional information and auxin. The relationship between positional information and other cellular informations in plant development was simpliy introduced.
