花粉管通过尖端生长迅速延伸。这个过程依赖于动态肌动蛋白细胞骨架，它参与控制花粉管中的细胞器运动、细胞质流动、囊泡运输和细胞质组织。在本次更新综述中，我们描述了理解肌动蛋白细胞骨架的组织和调节以及肌动蛋白细胞骨架在控制花粉管中囊泡运输和细胞质组织中的功能的进展。我们还讨论了离子梯度和肌动蛋白细胞骨架之间的相互作用，肌动蛋白细胞骨架调节肌动蛋白丝的空间排列和动力学以及花粉管中细胞质的组织。最后，我们描述了调节花粉管中肌动蛋白动态的几种信号传导成分。
Pollen tubes extend rapidly via tip growth. This process depends on a dynamic actin cytoskeleton, which has been implicated in controlling organelle movements, cytoplasmic streaming, vesicle trafficking, and cytoplasm organization in pollen tubes. In this update review, we describe the progress in understanding the organization and regulation of the actin cytoskeleton and the function of the actin cytoskeleton in controlling vesicle traffic and cytoplasmic organization in pollen tubes. We also discuss the interplay between ion gradients and the actin cytoskeleton that regulates the spatial arrangement and dynamics of actin filaments and the organization of the cytoplasm in pollen tubes. Finally, we describe several signaling components that regulate actin dynamics in pollen tubes.
