[Abstract]  Organisms have developed many protective systems to reduce the toxicity from heavy metals. The nematode Caenorhabditis elegans has been widely used to determine the protective mechanisms against heavy metals. Responses against heavy metals can be monitored by expression of reporter genes, while sensitivity can be determined by quantifying growth or survival rate following exposure to heavy metals. [摘要]  生物开发了许多保护系统,以减少重金属的毒性。线虫秀丽隐杆线虫已广泛用于确定重金属的保护机制。可以通过报告基因的表达来监测对重金属的反应,而敏感性可以通过量化暴露于重金属后的生长或存活率来确定。

背景 一些重金属如砷,镉和汞已知对包括人类在内的大多数生物有害(Valko et al。,2005)。为了降低这些金属的毒性,生物开发出各种保护系统。线虫秀丽隐杆线虫已被用于了解重金属的保护机制。以前的研究表明,许多基因,如解毒酶,转录因子和信号传导因子都参与了该生物体中重金属的保护(Broeks et al。,1996; Mizuno et al。 ,2004; Inoue等人,2005; Schwartz等人,2010)。除了测量报告基因表达外,生存力和生长的测定通常用于监测重金属在C中的影响。线虫。在本协议中,我们描述了使用C测定砷,铜和镉的方法。线虫。

[Abstract]  Plants sense potential pathogens by recognizing conserved pathogen-associated molecular patterns (PAMPs) that cause PAMP-triggered immunity (PTI) including the generation of reactive oxygen species, callose deposition, and expression of several PTI-related genes. Acidovorax avenae is a Gam-negative bacterium that causes a seedling disease characterized by the deposition of brown stripes on the sheaths of infected plants. We previously reported that flagellin isolated from the rice avirulent A. avenae N1141 strain induces PTI, while flagellin isolated from the rice virulent A. ... [摘要]  植物通过识别引起PAMP触发的免疫(PTI)的保守的病原体相关分子模式(PAMP)来感测潜在的病原体,包括活性氧的产生,胼lose质沉积和几个PTI相关基因的表达。 酸性弧菌是一种革兰氏阴性细菌,其导致幼苗疾病,其特征在于在感染的植物的鞘上沉积棕色条纹。 我们以前报告了从无毒力的大米中分离的鞭毛蛋白。 avenae N1141菌株诱导PTI,而从水稻毒力分离的鞭毛蛋白。 avenae K1株不诱导PTI。 为了检查N1141鞭毛蛋白的特异性PTI诱导的分子机制,需要来自N1141或K1菌株的高度纯化的鞭毛蛋白。 在这里,我们描述了一种高质量的纯化方法。 avenae鞭毛蛋白,并用于PTI诱导研究。

[Abstract]  An aquatic angiosperm Vallisneria (Alismatales: Hydrocharitaceae) has been used as an excellent experimental material over a century to study the light regulation of dynamic intracellular movements including chloroplast redistribution and cytoplasmic streaming (Senn, 1908; Seitz, 1987; Takagi, 1997). However, understanding of the molecular mechanisms lagged behind because of difficulty in applying modern techniques such as gene transformation to this plant. Especially, which kind of photoreceptors function in these intriguing responses has long been an unsolved topic. Recently, genes ... [摘要]  水生被子植物Vallisneria(Alismatales:Hydrocharitaceae)已经在一个世纪内用作研究动态细胞内运动的光调节的优良实验材料,包括叶绿体再分布和细胞质流(Senn,1908; Seitz,1987 ; Takagi,1997)。然而,对分子机制的理解落后,因为难以应用现代技术,如基因转化到这个植物。特别地,哪种类型的光感受器在这些有趣的反应中起作用长期以来一直是未解决的主题。最近,在水生植物中首次在Vallisneria中分离编码植物特异性蓝光受体光托品的基因(Sakai等人,2015)。光金蛋白首先被鉴定为拟南芥中下胚轴向往性的光感受器,并且现在已知调节许多反应,包括各种植物物种中的叶绿体光定位运动(Christie,2007)。光催化素主要位于质膜上,并且它们由蓝光诱导的自磷酸化是信号转导途径的关键步骤(Sakamoto和Briggs,2002; Kong等,2006; et al。,2013; Inoue et al。,2010)。在这里,我们描述了使用Vallisneria的原始微粒体和质膜富集级分的体外蛋白磷酸化测定的方案,其使得我们能够验证光催化素的存在并表征它们的自身磷酸化反应。在这些分析之后,Sakai等人(2015)提出 Vallisneria 光催化素介导高强度蓝光诱导的叶绿体回避反应。
