Biological membranes, especially the plasma membrane, are considered to be the most sensitive to altered gravity in regard to their properties and functions. We studied the composition and content of lipids, fatty acids and sterols in the plasma membrane fractions isolated from epicotyls and roots of Pisum sativum seedlings grown during 7 days under simulated microgravity by slow clinorotation. We demonstrate differences in the content of these membrane components of clinorotated and 1 g controls. The results indicate the high sensitivity of root plasma membrane to altered gravity conditions.

植物血浆膜对模拟微重力的敏感性

就其性质和功能而言,生物膜,尤其是质膜,被认为对重力变化最敏感。我们研究了在模拟微重力下缓慢倾斜旋转7天所生长的豌豆(Pisum sativum)幼苗的上胚轴和根中分离出的质膜组分中脂质,脂肪酸和固醇的组成和含量。我们证明了倾斜旋转和1 g控件的这些膜成分的含量差异 。结果表明根质膜对改变重力条件的高度敏感性。
