title: Membrane system organization in the process of greening of clinorotated barley seedlings.
abstract: Altered gravity affects on plastid structure and function during greening has not been studied. To elucidate how stimulated microgravity affects pigment apparatus formation in etiolated plants we have been studied clinorotation effects on morphological characteristics and chlorophylls biosynthesis in the first period of greening of barley plant. At the ultrastructural level clinorotation caused alteration of mesophyll cell parameters and organization, destruction of the fine structure of chloroplasts, changes in starch volume and lipid-protein accumulation.
