[Abstract]  Inducible gene expression systems offer researchers the opportunity to synchronize target gene expression at particular developmental stages and in particular tissues. The glucocorticoid receptor (GR), a vertebrate steroid receptor, has been well adopted for this purpose in plants. To generate steroid-inducible plants, a construct of GAL4-binding domain-VP16 activation domain-GR fusion (GVG) with the target gene under the control of upstream activation sequence (UAS) has been developed and extensively used in plant research.

Immune receptors perceive conserved molecular patterns ...
[摘要]  诱导型基因表达系统为研究人员提供了在特定发育阶段,特别是组织中同步靶基因表达的机会。糖皮质激素受体(GR),一种脊椎动物类固醇受体,已经在植物中被很好地用于此目的。为了产生类固醇诱导的植物,已经开发了在上游激活序列(UAS)控制下具有靶基因的GAL4结合结构域-VP16激活结构域-GR融合(GVG)的构建体,并广泛用于植物研究中。
免疫受体感知由病原体分泌的保守分子模式,并启动强烈的免疫应答。水稻免疫受体,XA21 识别在所有测序的黄单胞菌属的基因组中高度保守的分子模式,并且赋予对X的强抗性。 oryzae pv。 oryzae ( Xoo )。然而,鉴定XA21 下游的基因受到限制性损伤的阻碍,因此在表达Xa21 的植物中限制了防御反应区域。诱导型表达允许跨大量水稻组织的同步免疫应答,非常适合通过全基因组方法(例如转录组学和蛋白质组学)研究XA21 介导的免疫。在该协议中,我们描述了使用该GVG系统来同步 Xa21 表达。

[Abstract]  Anti-virulence agents against MRSA inhibit the production of disease-causing virulence factors, such as alpha-hemolysin, but are neither bacteriostatic nor bactericidal. Here we discuss a rapid method to screen for MRSA anti-virulence agents by measuring alpha-hemolysin production through ELISA. This protocol can be used with other alpha-hemolysin producing bacteria or for other excreted toxins to which antibodies exist. [摘要]  针对MRSA的抗毒剂抑制引起疾病的毒力因子如α-溶血素的产生,但既不是抑菌性的也不是杀细菌性的。 在这里我们讨论一种快速方法来筛选MRSA抗毒力试剂通过测量α-溶血素的生产通过ELISA。 该方案可以与其它产生α-溶血素的细菌或存在抗体的其它排泄毒素一起使用。
