SHORT-ROOT (SHR) is a key regulator of root growth and development in Arabidopsis (Arabidopsis thaliana). Made in the stele, the SHR protein moves into an adjacent cell layer, where it specifies endodermal cell fate; it is also essential for apical meristem maintenance, ground tissue ...
SHORT-ROOT (SHR) is a well-characterized regulator of radial patterning and indeterminacy of the Arabidopsis (Arabidopsis thaliana) primary root. However, its role during the elaboration of root system architecture remains unclear. We report that the indeterminate wild-type Arabidopsis root system was...

The SHORT ROOT (SHR) gene, a member of the GRAS family of putative transcription factors, is involved in root radial patterning in Arabidopsis. Correct radial patterning depends on the positional information transmitted through limited SHR intercellular movement and translated into cell division and ...
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。关键词 辐射形态, SHORT-ROOT, 信号网络, 转录因子高潜, 刘玉瑛, 费一楠, 李大朋, 刘祥林 (2008). 拟南芥...
In Arabidopsis, formative divisions generating the root ground tissue are controlled by SHORTROOT (SHR) and SCARECROW (SCR). Here we show, using cell-type-specific transcriptional effects of SHR and SCR combined with data from chromatin immunoprecipitation-based microarray experiments, that SHR ...
在使用直向同源ZmSHR1基因,以避免OsSHR2的潜在沉默的转基因株系中,在正常位置和距离叶脉更远的位置都观察到气孔细胞。与理论预测相反,以及在双子叶植物叶片中观察到的表型,气孔密度的增加不提高光合能力或增加叶肉细胞密度。总的来说,这些结果表明SHORTROOT途径可以协调静脉和气孔在单子叶植物叶片中的定位,并且在...
To test whether the pathway has the potential to similarly pattern epidermal cell-types, we expanded the expression domain of the rice OsSHR2 gene, which we show is restricted to developing leaf veins, to include bundle sheath cells encircling the vein. In transgenic lines, which were generated...
HRV and APV were different between SHR and WKY rats; however, no differences in these parameters were found between the animals with PD and their control counterparts. Plasma NO and myocardial IL-1β concentrations were higher in SHR with PD as compared to control WKY. A significant correlation...
