Measuring Secretion of Capsidiol in Leaf Tissues of Nicotiana benthamiana

[Abstract]  Plant species produce a wide variety of antimicrobial metabolites to protect themselves against potential pathogens in natural environments. Phytoalexins are low molecular weight compounds produced by plants in response to attempted attacks of pathogens. Accumulation of phytoalexins in attacked plant tissues can inhibit the growth of penetrating pathogens. Thus phytoalexins play a major role in post-invasion defense against pathogens. Major phytoalexins produced by Solanaceous plants are sesquiterpenoids such as capsidiol produced by Nicotiana and Capsicum species, and rishitin produced by Solanum species, which are synthesized in the cytosol and secreted into the intercellular space of plant tissues. We previously reported that deficiency in capsidiol secretion ... [摘要]  植物物种产生多种抗微生物代谢物,以保护自身免受自然环境中潜在的病原体的侵害。植物毒素是由植物响应于病原体的企图攻击而产生的低分子量化合物。植物抗毒素在受攻击的植物组织中的积累可以抑制穿透性病原体的生长。因此,植物抗毒素在入侵后对抗病原体的防御中起主要作用。茄科植物产生的主要植物抗毒素是倍半萜类化合物,如由 Nicotiana 和 Capsicum 物种产生的衣壳菌素,以及由 Solanum 物种产生的rishitin,其在胞质溶胶分泌到植物组织的细胞间隙中。我们以前曾报道,衣壳菌素分泌不足会导致本塞姆氏烟草对马铃薯晚疫病菌致病疫霉的敏感性增加。在这里,我们描述了一种测量 N中分泌的衣壳二醇的实用方案。本塞姆氏

【背景】该方案提供了一种快速简便的方法来量化衣壳菌醇的分泌,如Shibata 等(2016)所述。 因为环己烷通常用作洗去花粉层的溶剂,但能保持花粉活力(Doughty et al。,1993),我们开发了这种方法从叶子表面洗去分泌的代谢物来量化细胞外capsidiol。 可以使用该方法分析质膜局部转运蛋白的功能,同时还允许其与其他方法结合使用,例如使用质膜囊泡的生化转运分析(例如,Sugiyama 等人,,2007),以确定所检查的转运蛋白的底物。

Xylem Sap Extraction Method from Hop Plants

[Abstract]  Verticillium wilt is one of the most important diseases on hop that significantly influence continuation of production on affected areas. It is caused by the soil borne vascular pathogen Verticillium nonalfalfae, which infects plants through the roots and then advances through the vascular (xylem) system. During infection, V. nonalfalfae secretes many different virulence factors. Xylem sap of infected plants is therefore a rich source for investigating the molecules that are involved in molecular interactions of Verticillium – hop plants. This protocol provides instructions on how to infect hop plants with V. nonalfalfae artificially and how to obtain xylem sap from hop plants. [摘要]  黄萎病是最重要的疾病之一,对受影响地区的生产继续产生重大影响。它是由土壤传播的血管病原体疣黄萎病引起的,其通过根感染植物,然后通过血管(木质部)系统前进。感染期间,非苜蓿科分泌许多不同的毒力因子。因此感染植物的木质部汁液因此是调查涉及轮枝孢属植物的分子相互作用的分子的丰富来源。该协议提供有关如何用V感染啤酒花植物的说明。人工制备非苜蓿,如何从啤酒花植物获得木质部汁液。

背景 从植物中提取木质部汁液主要用于木质部汁液蛋白质组学的研究,并且已经使用各种方法从植物木质部组织中提取汁液。 Buhtz等人。 (2004)使用手持式移液器从切割的植物茎收集木质部汁液,用于比较不同植物(西兰花,油菜,南瓜和黄瓜)中的木质部蛋白质组。采用相同的方法从欧洲油菜中收集木质部汁液(Kehr等,2005),芸苔属(Ligat et al。,et al。 al。,2011)和大豆(Subramanian等人,2009)。 Alvarez等人。 (2006)使用“根压力”提取玉米木质部汁液蛋白质组,如Goodger等人所述。 (2005)。 Dafoe和Constabel(2009)使用安装在木材上的Tygon管,从混合杨树收集木质部汁液,并且不施加额外的压力。关于木质部汁液的蛋白质含量的信息也适用于苹果,梨和桃子(Biles and ...
