Lipid peroxidation of plants under microgravity and its simulation.
In series of space experiments aboard the biosatellites "Cosmos 1887", "Bion 9", the orbital stations "Salut", "Mir" and under clinostating, changes of lipid peroxidation (LPO) and antioxidation activity (AOA) of Chlorella, Haplopappus tissue culture, wheat and pea roots were determined.  The changes had a complex fluctuation character; three steps of response were established:  LPO decreasing accompanied by AOA increase; stabilization LPO <==> AOA balance; secondary LPO activation.  Most early and highly amplitude decreasing of LPO were fixed in mitochondria.  The rate of response have been increased on multicellular level of plants organization.
