簡要描述：Structural proteins in Arabidopsis provide cellular stability, facilitate protein transportation within the cell and are essential for cell growth. Three types of molecular motors are involved in the organization, dynamics and transport processes associated with the cytoskeleton (1). They include myosin, which transports cargo along actin filaments, and kinesin and dynein, which transport cargo along microtubules (1,2). These proteins regulate many cellular functions, including cell divisio
