The study of the functional state of lipid rafts in the cytoplasmic membrane of Pisum Sativum seedlings under clinorotation

The results of cytological, biochemical, and molecular biological studies clearly demonstrate the significant influence microgravity on main processes plant development, revealing mechanisms which underlie reactions responses to ensure their adaptation this factor. key role in cell function belongs cytoplasmic membrane (CM). First all, by its qualities functions, it can play an important plants microgravity. However, data about effect altered gravity physicochemical properties CM are limited. Recently, much attention has been paid study functional microdomains lipid bilayer that have a specific localization content lipids proteins - rafts. They defined as dynamic nanosized, sterol- sphingolipid-enriched ordered association proteins, metastable resting state be activated combination lipid-lipid, protein-lipid, protein-protein interactions. There more experimental confirm participation such live endocytosis, apoptosis, internalization toxins, bacteria, viruses, etc., well protective under different stressors. In work, fluorescent marker sterols – filipin probe laurdan were used presence cholesterol ranges CM. Our regarding increase generalized polarization clinorotation conditions correlate with obtained previous indicate sensitivity longer action clinorotation.
