摘　　要：微丝骨架作为细胞骨架的一种 ,它在细胞的许多功能活动中起重要作用。近年来 ,研究证明微丝骨架受信号转导的调节。动物细胞中存在着细胞外基质 (ECM ) 质膜 (PM ) 细胞骨架(CTK)连续体 ,胞内、外信号可以通过此连续体进行双向传递。研究还证明 ,植物细胞中存在细胞壁 (CW ) 质膜 (PM ) 细胞骨架 (CTK)连续体 ,并认为它类似于动物细胞中的ECM PM CTK连续体 ,有着相同的功能。As one of the cytoskeletons, microfilament is important in many cell functions. In recent years, evidences show that microfilament is regulated by the signal transdution. There are a extracelluar matrix (ECM) plasma membrane (PM) cytoskeleton (CTK) continuum in animal cell. The intracelluar or extracelluar signals may be transmitted bidirectionally, that is from the ECM to the CTK and vice versa. Recent evidences also show that plant cell may have a cell wall (CW) plasmalemma (PM) cytoskeleton (CTK) continuum. This continuum is similar to and funtionally parallels that of animal systems. We also described the main signaling pathways that regulate the microfilament cytoskeleton.
