[Abstract]  Ensifer adhaerens OV14, a soil borne alpha-proteobacteria of the Rhizobiaceae family, fortifies the novel plant transformation technology platform termed ‘Ensifer-mediated transformation’ (EMT). EMT can stably transform both monocot and dicot species, and the host range of EMT is continuously expanding across a diverse range of crop species. In this protocol, we adapted a previously published account that describes the use of Arabidopsis thaliana roots to investigate the interaction of A. thaliana and Agrobacterium tumefaciens. In our laboratory, we routinely use A. thaliana root explants to examine the factors that enhance the utility of EMT. In addition, the E-ART protocol can be used to study the transcriptional response of E. ... [摘要]  OV14;土壤传播的根瘤菌科的α-变形细菌强化了新型植物转化技术平台,称为“插入式”介导的转化(EMT)。 EMT可以稳定地转化单子叶植物和双子叶植物,并且EMT的宿主范围在不同范围的作物种类上不断扩大。在这个协议中,我们调整了一个以前发布的帐户,描述了使用拟南芥根系来研究 A的相互作用。 thaliana 和根癌土壤杆菌。在我们的实验室,我们通常使用 A。 thaliana 根外植体,以检查增强EMT效用的因素。此外,E-ART协议可用于研究E的转录反应。接种外植体组织后的寄主植物,宿主植物,不同的引物菌株/突变体的可变性以及测试A的易感性。作为破译支持EMT的机制的手段。【背景】推进“Ensifer”介导的转化(EMT)技术以成功地转化双子叶菊,即拟南芥,马铃薯Solanum tuberosum ,Nicotiana tabacum ,Manihot esculenta ,欧洲油菜和单子叶植物;之前曾报道过(Wendt等人,2012; Zuniga-Soto等人),2015; Chavarriaga-Aguirre et al。,2016; Rathore等人,2016)。另外,E的基因组分析。 (2014)发现,该细菌具有7.7Mb的基因组,其包含两条环状染色体(3.96Mb和2.01Mb)和两条质粒(1.61Mb和125Kb) )。 ...

Protocol for Increasing Carotenoid Levels in the Roots of Citrus Plants

[Abstract]  Carotenoids in plants play several key functions such as acting as light-harvesters, antioxidants (Lado et al., 2016) or being precursors of strigolactones, abscisic acid, volatiles and other signaling compounds (Arbona et al., 2013). Although those functions are well-known in light-exposed tissues, information in belowground organs is limited because of reduced abundance of these pigments. In order to better understand the role of carotenoids in roots, we developed a methodology to increase the abundance of these pigments in underground tissues. We took advantage of the fact that citrus roots exposed to light develop pigmentation in order to increase the carotenoid content. Therefore, here we describe a simple method to increase carotenoids in citrus roots. [摘要]  植物中的类胡萝卜素起着几个关键作用,例如作为轻收割机,抗氧化剂(Lado等人,2016),或作为角闪石内酯,脱落酸,挥发物和其他信号传导化合物的前体(Arbona et al。,2013)。虽然这些功能在光暴露的组织中是众所周知的,但是由于这些颜料的丰度降低,地下器官中的信息受到限制。为了更好地了解类胡萝卜素在根中的作用,我们开发了一种增加地下组织中这些颜料丰度的方法。我们利用了暴露于光的柑橘根发现色素沉淀以增加类胡萝卜素含量的事实。因此,这里我们描述一种增加柑橘根类胡萝卜素的简单方法。

背景 根中的类胡萝卜素丰度是非常有限的,因此,理解这些化合物的作用变得困难。根部对光线的曝光是增加这些组织中类胡萝卜素水平的简单,快速和有用的工具,特别是当与其他基因组方法相比较时,例如过度表达类胡萝卜素生物合成途径的一些关键基因(Cao等人,2015)。
