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.
本文展示了关于豌豆幼苗根在回转5天后根尖线粒体超微结构、组织呼吸以及从根尖分离出的细胞器代谢活性的实验数据。结果表明，根尖远端伸长区的线粒体凝聚与氧气吸收速率增加7%相关。我们还观察到苹果酸氧化速率增加，呼吸控制率同时增加，而氧化磷酸化效率降低。模拟微重力条件下线粒体的这种重排特征被认为是对这些条件适应的结果。
