Fundamental research on the possibilities of adaptation of plants to space flight conditions, which are of direct application for the development of space crop technologies in bioregenerative life support systems in long space flights, in recent years has risen to a new level by improving microchips and two-dimensional electrophoresis. gene expression, composition and protein content. It is shown that under the influence of these factors changes the expression of a significant number of genes involved in a wide range of cellular processes, in particular in stress responses, signaling, including calcium ions, protein synthesis, total metabolism, chlorophyll-associated proteins a / b, etc. In general, the results of cytological, biochemical and molecular biological studies clearly demonstrate the significant impact of microgravity іn key plant development processes, while revealing the mechanisms underlying plant responses to microgravity and ensure plant adaptation to this factor. We have proposed a new direction for understanding the gravity sensitivity of plants - the study of the effect of real and simulated microgravity on biological membranes, especially the cytoplasmic membrane, as their properties and functions can be considered as the most sensitive indicators of gravity or altered gravity on the cell.
