title: Formation and growth of callus tissue of Arabidopsis under changed gravity.
abstract: 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.
