Lipid Droplet Isolation from Arabidopsis thaliana Leaves

[Abstract]  

Lipid droplets (LDs) are neutral lipid aggregates surrounded by a phospholipid monolayer and specific proteins. In plants, they play a key role as energy source after seed germination, but are also formed in vegetative tissues in response to developmental or environmental conditions, where their functions are poorly understood. To elucidate these, it is essential to isolate LDs with good yields, while retaining their protein components. LD isolation protocols are based on their capacity to float after centrifugation in sucrose gradients. Early strategies using stringent conditions and

[摘要]  [摘要]脂质滴(LDs)是被磷脂单层和特定蛋白质包围的中性脂质聚集体。在植物中,它们在种子发芽后作为能源起着关键作用,但由于发育或环境条件而对其功能了解甚少,它们也在营养组织中形成。为了阐明这些,必须分离出具有高产率的LD,同时保留其蛋白质成分。LD分离方案基于其在蔗糖梯度中离心后的漂浮能力。早期使用严格条件和LD丰富的植物组织的策略产生了可鉴定核心蛋白的纯LD。为了鉴定更弱结合的LD蛋白,最近的研究otocols使用了低严格性的缓冲液,但是残留污染物和低收率通常是个问题。我们已经开发了一种基于蔗糖梯度的方案,可使用Tween-20和新鲜组织从拟南芥叶中分离LD,以提高产量。在健康和细菌感染的拟南芥叶片中,该方案均允许鉴定LD蛋白,随后通过显微镜分析对其进行确认。

背景]脂质降住所(LD)的通过由磷脂单层,其中LD蛋白插入包围的中性脂质核心组成的细胞器(Tzen等人,1993) 。LD首先被描述为稳定的隔室,用于在特殊组织中存储高能脂质。然而,最近的评论将LDs描述为大多数细胞类型中存在的高度动态的细胞器,其功能超越了单纯的能量存储(Shimada等人,2018; Huang,2018; Shao等人,2019)。

[Abstract]  This protocol is to differentially and simultaneously visualize both cells and airspaces in intact leaves and to create 3D structures of cells and airspaces from confocal images using the software DSLT_Demo (https://github.com/nslab2000/DSLT). Leaves stained with Nile Red in silicone-oil solution provide red color to cell membranes and green color to airspaces filled with silicone oil solution. This method is applicable to any tissues (except for dry seeds) of various plants including Arabidopsis, Nicotiana, Lemna ... [摘要]  此协议是差异和同时可视化完整叶片的细胞和空间,并使用软件DSLT_Demo( https://github.com/nslab2000/DSLT )。 用尼罗红在硅油溶液中染色的叶子为细胞膜提供红色,并向填充有硅油溶液的空间提供绿色。 该方法适用于包括拟南芥 ,,, 和moss在内的各种植物的任何组织 硬叶植物如柳枝稷和樟脑。 重复使用这种方法使得叶片在几天和几周时间推移成像,因为尼罗红和硅油都对植物组织无害。
