Abstract Using electroncytochemical and biochemical methods, differences between the cytochemical reaction intensity and activity of the cellulosolytic enzymes in Funaria hygrometrica moss cells grown for 30 days in the horizontal clinostate (2 rev/min) and in control have been studied. It has been shown that on clinostating the precipitate amount and size increases with the cellulase activity enhancement in the periplasmic space and protonema cell walls, when compared to control. Using biochemical methods it has been found that the activity of both endo-1,4- β -glucanase and exo-1,4- β -glucanase was higher under these conditions. A decrease of cellulose total content, its crystalline form, and pectic substances as well as an increase of hemicellulose content have been revealed in the clinostated material compared to control. Data obtained are discussed regarding the possible mechanism of cellulase activation and synthesis inhibition and cellulose crystallization in plant cell walls at clinostating.im]0102.TIF
