[Abstract] The plant Golgi apparatus is composed of numerous stacks of cisterna, designated as cis, medial, and trans Golgi cisternae; these stacks move within the cytoplasm along the actin cytoskeleton. Cis cisternae receive secretory products from endoplasmic reticulum (ER) and they subsequently progress through the stack to the trans cisternae, where they are sorted to other destinations, including cell wall, plasma membrane (PM), vacuoles, and chloroplasts. In addition, the plant Golgi apparatus plays a role of glycosylating proteins as well as synthesizing cell wall polysaccharides, such as hemicelluloses and pectins. This protocol describes procedures for imaging fluorescently-tagged proteins localized to the plant Golgi apparatus of Arabidopsis ...
[摘要] 植物高尔基体包括许多叠状体，称为顺，内侧和反式高尔基这些堆栈在细胞质内沿着肌动蛋白细胞骨架移动。 Ctern 池从内质网（ER）接收分泌产物，并且随后通过堆叠进入反转池，在那里它们被分选到其他目的地，包括细胞壁，血浆膜（PM），液泡和叶绿体。此外，植物高尔基体起到糖基化蛋白质以及合成细胞壁多糖如半纤维素和果胶的作用。该协议描述了使用共聚焦激光显微镜（CLSM），全内反射荧光显微镜（TIRF）和高压的免疫金标记标记定位于拟南芥幼苗的植物高尔基体的荧光标记的蛋白质的程序冷冻/冷冻取代的样品通过透射电子显微镜（TEM）。我们特别关注长期时间推移成像和蛋白质本地化在高尔基内的子域。该方案还可以用于其他细胞器，组织和植物物种。
