摘要

Results of the electron-microscopic investigation ofrnroot apices of Arabidopsis thaliana 3– and 7–day oldrnseedlings grown in the stationary conditions and underrnclinorotation are presented. It was shown the similarityrnin the root apex cell ultrastructure in control and underrnclinorotation. In the same time there were somerndifferences in the ultrustructure of statocytes and therndistal elongation zone under clinorotation. For the firstrntime, the sensitivity of ER-bodies, which are derivativernof granular endoplasmic reticulum and contain a β-rnglucosidase enzyme, to the influence of simulatedrnmicrogravity that was demonstrated by increasingrnquantity and area of ER-bodies per cell section, as wellrnas by higher variability of their shape underrnclinorotation. A degree of these changes correlatedrnwith the duration of clinorotation. On the basis ofrnobtained data, a protective role of ER-bodies inrnadaptation of plants to microgravity is discussed.
