Ultrastructure and metabolic activity of pea mitochondria under clinorotatio
SUMMARY. Experimental data on the mitochondrial ultrastructure and tissue respiration in root apex as well as metabolic activity of the organelles isolated from pea seedling roots after 5-day of clinorotation are presented. It was shown that mitochondrial condensation in the distal elongation zone correlated with an increased rate of oxygen uptake on 7 %. We also observed increase in rate of malate oxidation and respiratory control ratio increased simultaneously with a decreased in efficiency of oxidative phosphorylation. Such character of mitochondrial rearrangements in simulated microgravity is assumed to be a consequence of adaptation to these conditions.
