摘　　要：综述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．Plasmodesmal origin and secondary modification are compared between higher plant and lower plant. Structurally modified plasmodesmata give rise to giga channel(100￣1 000 nm) because of activation of enzymes. Gene expression and organogenesis are regulated by informational macromolecules which are trafficked in intercellular channel.

关 键 词：胞间通道 植物 细胞分裂 胞间连丝
