Abstract  The actin cytoskeleton is involved in numerous physiological processes of eukaryotes. Actin is evolved from a common protist ancestor, and the biochemical characteristics and the dynamics of actin are similar in eukaryotic cells. However, there are some differences in the existing pattern of actin cytoskeleton, the type of actin binding proteins (ABPs) and the mechanisms underlying the regulation of actin dynamics between animal and plant cells owing to the diverse of cell type and physiological processes. This review will focus on the advances and summarize the function of actin in the several novel physiological processes of plants.
