摘要
通过对胞间连丝的起源、形成及其调控物质运输机理的讨论，说明胞间连丝是物质运输和信息传递的重要通道。并且比较了高等植物和低等植物胞间连丝的发生和次生变化。由于酶的作用，胞间连丝向胞间通道转化，形成了约１００～１０００ｎｍ的开放性通道。
Through the discussion of the origin, formation and mechanism of regulating material transportation of plasmodesmata, it shows that plasmodesmata plays an important role in material transportation and signal transduction. Plasmodesmal origin and secondary modification are compared between higher plant and lower plant also. Structurally modified plasmodesmata give rise to giga channel (100～1000 nm) because of activation of enzymes.
