摘要: 从模式植物拟南芥中克隆得到的SHORT-ROOT基因(SHR)被证明参与根部形态建成途径。目前已知SHR是与根辐射形态直接相关的重要调控因子, 同时也参与维持根尖分生组织的活性。SHR既作为转录因子启动下游基因的表达, 又作为短程信号调节根的发育。本文综述了SHR相关研究进展, 并展望其研究前景。

Abstract: The SHORT-ROOT (SHR) gene, first cloned from Arabidopsis thaliana, is a key regulator not only in root radial patterning but also in root meristem maintenance. Currently, SHR is characterized as both a transcription factor for activating downstream gene expression and a short-range signal for modulating root development. In this paper, we review recent research and provide prospective views of this field.
