Root Aliphatic Suberin Analysis Using Non-extraction or Solvent-extraction Methods

[Abstract]  Here we describe both non-extraction and solvent-extraction methods for root aliphatic suberin analysis. The non-extraction method is fast as roots are directly depolymerized using acidic transmethylation. However, suberin aliphatic components are isolated together with all the other acyl chains making up the lipids (e.g., membranes) present in roots. For the solvent-extraction method, roots are first delipidated before transmethylation. This method is longer but allows separation of soluble and polymerized root lipids. This protocol is optimized for tissue culture- or soil-grown Arabidopsis thaliana plants, but can be used with roots of other plants. [摘要]  在这里我们描述了非提取和溶剂萃取方法的根脂肪族苏维林分析。 非提取方法快速,因为根使用酸性转甲基化直接解聚。 然而,苏维林脂族组分与构成根中存在的脂质(例如膜)的所有其它酰基链一起分离。 对于溶剂萃取方法,首先在转甲基化之前使根脱皮。 该方法较长,但可分离可溶性和聚合的根脂质。 该方案针对组织培养或土壤种植的拟南芥植物进行了优化,但可与其他植物的根一起使用。
【背景】Suberin是沉积在各种组织的细胞壁中的细胞外植物脂质聚合物,例如根内皮,外皮和根周围。 Suberin作为控制水和溶质通量并限制病原体感染的屏障(Ranathunge et al。,2011; Andersen等,2015; Vishwanath等,2015; Barberon等,2016)。 Suberin是由脂类,酚类和甘油组成的复杂杂聚物,与溶剂萃取蜡相关(Bernards,2002)。在拟南芥模拟植物中,苏维林聚合物主要由ω-羟基酸和α,ω-二羧酸制成,但也含有未取代的脂肪酸和伯醇脂肪醇(Domergue等,2010; Vishwanath et al。 2013),而相关的蜡是羟基肉桂酸烷基酯(AHC; Kosma等,2012; ...
