Plasmodesmata (Pd) are channels in the plant cell wall that in conjunction with associated phloem form an intercellular communication network that supports the cell-to-cell and long-distance trafficking of a wide spectrum of endogenous proteins and ribonucleoprotein complexes. The trafficking of such macromolecules is of importance in the orchestration of non-cell autonomous developmental and physiological processes. Plant viruses encode movement proteins (MPs) that subvert this communication network to facilitate the spread of infection. These viral proteins thus represent excellent experimental keys for exploring the mechanisms involved in intercellular trafficking and communication via Pd.
胞间连丝（Pd）是植物细胞壁中的通道，它与相关韧皮部共同形成一个细胞间通讯网络，该网络支持多种内源性蛋白质和核糖核蛋白复合物在细胞间和长距离的运输。这种大分子的运输在非细胞自主发育和生理过程的协调中具有重要意义。植物病毒编码运动蛋白（MPs），这些蛋白会破坏这种通讯网络以促进感染的传播。因此，这些病毒蛋白是探索通过胞间连丝进行细胞间运输和通讯所涉及机制的绝佳实验关键。
