Intracellular transport in plant cells occurs on microtubular and actin arrays. Cytoplasmic streaming, the rapid motion of plant cell organelles, is mostly driven by an actin-myosin mechanism, whereas specialized functions, such as the transport of large cargo or the assembly of a new cell wall during cell division, are performed by the microtubules. Different modes of transport are used, fast and slow, to either haul cargo over long distances or ascertain high-precision targeting, respectively. Various forms of the actin-specific motor protein myosin XI exist in plant cells and might be involved in different cellular functions.
植物细胞中的细胞内运输发生在微管和肌动蛋白阵列上。细胞质流动，即植物细胞器的快速运动，主要由肌动蛋白-肌球蛋白机制驱动，而诸如大型货物运输或细胞分裂期间新细胞壁组装等特殊功能则由微管执行。分别使用快速和慢速等不同的运输方式，将货物远距离运输或实现高精度靶向。植物细胞中存在多种形式的肌动蛋白特异性运动蛋白肌球蛋白XI，它们可能参与不同的细胞功能。
