[The modern problems of space cell phytobiology]

This monograph has summarized the results of space experiments fulfilled over the last 25 years on lower and higher plants cell and tissue cultures in vitro being physiologically active during the space mission. A considerable attention has been paid to the calcium ions role in biological effects at the cellular and subcellular levels of microgravity and clinostating, physical-chemical features of cytoplasmic membrane and lipid peroxidation of plant cells under conditions of gravity variations. The rearrangement patterns of the plant cell structural-functional organization affected by microgravity and clinostating and probable mechanisms of cell adaptation to these factors are discussed.
