Formation and growth of callus tissue of Arabidopsis under changed gravity.
The changed gravity conditions do not prevent the process of cell dedifferentiation and formation of callus.  Yet, callus grown on the clinostat and in space differs from the control one:  its consistence is denser, occurence of meristematic centres is less frequent and it shows a reduced proliferative activity of cells.  Average size of cell and nuclei area in the test variants is lower than in the control.
