Dynamics of full-length Arabidopsis myosin XI and its involvement in actin remodeling.

ABSTRACT: Plant myosin XI plays a crucial role in intracellular transport, known as cytoplasmic streaming. Previous studies have identified associations between myosin XI and organelles by using a cargo-binding tail domain that lacks a motor domain. However, the subcellular localization and dynamics of full-length myosin XI remain poorly understood. Here, we report the imaging of green fluorescent protein (GFP)-fused full-length Arabidopsis myosin XI by transient expression in Nicotiana benthamiana leaves. Live-cell imaging revealed that the localization of several members of full-length Arabidopsis myosin XI differed from that of their respective tail domains. Of these myosin XI members, we focused on myosin XI-2, a major driving force of cytoplasmic streaming. Full-length myosin XI-2 localized to
