Microscopic Observation of Subcellular GFP-tagged Protein Localization in Rice Anthers

[Abstract]  This protocol demonstrates a simple method to determine the subcellular localization of fluorescence-tagged proteins on the vibratome sections of rice developing anthers. If a cell type-specific promoter is used to drive the tagged protein-encoding gene, the method enables to clearly distinguish the cells retaining fluorescent signals from other anther cells. It is applicable to both live and fixed samples, and presumably to other plant tissues. [摘要]  该方案演示了一种确定荧光标记蛋白在水稻发育花药的振动切片上的亚细胞定位的简单方法。 如果使用细胞类型特异性启动子来驱动标记的蛋白质编码基因,该方法能够清楚地区分保留荧光信号的细胞与其他花药细胞。 它适用于活的和固定的样品,并且可能适用于其他植物组织。

Histochemical Staining of Silica Body in Rice Leaf Blades

[Abstract]  Silicon (Si) is a biologically important element for plants in the order Poales (Yamamoto et al., 2011; Kido et al., 2015). In rice, Si is mainly deposited in the motor cells and the cell walls of the leaf epidermis. However, the molecular basis of this overall process has not been elucidated. Thus, we propose a protocol for the histochemical staining of the silica body based on specific hydrogen bonding between silanol group and the carboxylate group of crystal violet lactone (Ichimura et al., 2008), as described by Isa et al. (2010), but with minor ... [摘要]  硅(Si)对于Poales(Yamamoto等人,2011; Kido等人,2015年)的植物是重要的生物元素。 在稻中,Si主要沉积在运动细胞和叶表皮的细胞壁中。 然而,该整个方法的分子基础尚未阐明。 因此,我们提出了用于基于硅烷醇基团和结晶紫内酯的羧酸酯基团之间的特异性氢键的二氧化硅体的组织化学染色的方案(Ichimura等人,2008),如Isa (2010),但稍作修改。 这个修改的协议可以用于观察水稻开发过程中的硅积累。
