Mechanism of Inhibition of Cells of Hydrocharis CytoplasmicStreaming by Auxin in Root Hair

rupted cortical microtubules (MTs). The effects of NAA were reyers;b)e; both cytop]asmic streaming and organization of the cytoskeleton were recovered upon remoyal of NAA. During the recoyery, tracks of cytop)asmic streaming in the subcortical region temporarily showed a helical pattern along the longitudinal direction of the cell. Fluorescence staining of cytoskeletons reyea]ed that both AFs and MTs aligned obliqlle]y to the longitudinal axis of the
