植物细胞和神经元有几个相似之处，包括非中心体微管，能动的高尔基后细胞器，在空间/结构和功能上与高尔基体分离，并参与囊泡内吞再循环，以及基于肌动蛋白/肌球蛋白细胞骨架的细胞-细胞粘附结构域，用于细胞-细胞通讯。尖端生长的植物细胞，如根毛和花粉管，也类似于神经元延伸它们的轴突。最近，关于神经退行性疾病的分子基础已经有了令人惊讶的发现，这些神经退行性疾病被称为遗传性痉挛性截瘫和根毛尖端生长。所有这些进展简要讨论的背景下，植物细胞和神经元之间的其他相似之处。
Plant cells and neurons share several similarities, including non-centrosomal microtubules, motile post-Golgi organelles, separated both spatially/structurally and functionally from the Golgi apparatus and involved in vesicular endocytic recycling, as well as cell-cell adhesion domains based on the actin/myosin cytoskeleton which serve for cell-cell communication. Tip-growing plant cells such as root hairs and pollen tubes also resemble neurons extending their axons. Recently, surprising discoveries have been made with respect to the molecular basis of neurodegenerative disorders known as Hereditary Spastic Paraplegias and tipgrowth of root hairs. All these advances are briefly discussed in the context of other similarities between plant cells and neurons.
