摘要：

The organization and distribution of microfilaments (MFs) in the preprophase (PPBs) of tobacco (Nicotiana tabacum L. var. Maryland Mammoth) root tip cells were studied with high pressure freezing and freeze-substitution methods. MFs were Present predominantly as single filaments interspersed among microtubules (MTs) throughout the PPB. Some MFs appeared to be associated with MTs, whereas others were not. This is the first time that MFs have been demonstrated in the PPB at the electron microscope level.
