摘要

Results of the electron-microscopic investigation of root apices of Arabidopsis thaliana 3– and 7–day old seedlings grown in the stationary conditions and under clinorotation are presented. It was shown the similarity in the root apex cell ultrastructure in control and under clinorotation. In the same time there were some differences in the ultrustructure of statocytes and the distal elongation zone under clinorotation. For the first time, the sensitivity of ER-bodies, which are derivative of granular endoplasmic reticulum and contain a β- glucosidase enzyme, to the influence of simulated microgravity that was demonstrated by increasing quantity and area of ER-bodies per cell section, as well as by higher variability of their shape under clinorotation. A degree of these changes correlated with the duration of clinorotation. On the basis of obtained data, a protective role of ER-bodies in adaptation of plants to microgravity is discussed.
