摘要: 位置信息是植物发育的重要机制之一, 它在植物体的模式建成、细胞的分化及细胞命运的抉择过程中起重要作用。近些年的研究从细胞壁、激素、可扩散因子和非转录DNA等角度对这一问题进行了大量探索, 成为植物发育生物学的一个热点领域。本文试对此作一简要介绍。

关键词: 位置信息, 细胞命运, 信号转导, 植物发育

Abstract: Positional information is one of the important mechanisms underlying plant development because it is involved in pattern formation, cell differentiation and cell fate determination.Current studies indicate that positional information is related to certain kind of hormones, diffusible molecules or non-transcribed DNA and even molecule(s) localized in cell walls. Positional information may be a collaborative effect that involves these molecules and signaling.

Key words: Positional information, Cell fate, Signaling transduction, Plant development
