[The growth and differentiation of root cap columella cells and the proper root grown in the stationary conditions and under clinorotation].
The results of light- and electron-microscopic investigations of root apices of Beta vulgaris 3-day-old seedlings grown in the stationary conditions and under clinorotation are presented. It was shown that ultrastructure and topography of organelles in root cap statocytes (graviperceptive cells) and in the cells of distal elongation zone clearly reflected the different direction in their growth and differentiation in space and time in dependence on specialization and functions. Cell growth and genetically determined differentiation occur similarly to control, although certain differences in ultrastructure are evident on metabolism changes.
