In vitro CLE Peptide Bioactivity Assay on Plant Roots

[Abstract]  Plant CLAVATA3/ESR (CLE)-related proteins play diverse roles in plant growth and development including regulating the development of root meristem. The mature functional forms of CLE peptides are typically 12-13 amino acids (aa) in length that are derived from the conserved C-termini of their precursor proteins. Genes encoding small secreted peptides sharing similarity to plant CLE proteins have recently been cloned from plant-parasitic nematodes, pests that infect many important crops. It is demonstrated that exogenous application of synthetic 12-14 aa CLE peptides corresponding to the CLE ... [摘要]  植物CLAVATA3/ESR(CLE)相关蛋白质在植物生长和发育中发挥多种作用,包括调节根分生组织的发育。 CLE肽的成熟功能形式通常为12-13个氨基酸(aa)长度,其衍生自其前体蛋白的保守C-末端。 最近从植物寄生线虫,感染许多重要作物的害虫克隆了编码与植物CLE蛋白相似的小分泌肽的基因。 证明外源应用对应于其前体蛋白的CLE结构域的合成12-14aa CLE肽可以抑制植物根生长。 该协议是通过测量CLE肽处理后植物根的生长或根尖分生组织(RAM)的大小来评价源自植物寄生线虫的CLE肽的生物活性。 用于研究的植物包括拟南芥和马铃薯。

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。
