The Wheat Thylakoid Lipid Content Affected by Heat

Abstract

Plants are impacted by unfavourable factors of the environment — drought, heat, frost etc. on the significant areas of different soil climatic regions of Europe. On solving the problem of physiological and biochemical mechanisms of plant acclimation and resistance, special emphasis is laid on the physical properties of photosynthetic membranes, their ability to provide the conditions needed for normal functioning enzymes and proteins — carrier of electrons(1, 2). Lipids in interaction with sterols, carotenoids and proteins are substances determining molecular structure, physical and chemical properties, and functional activity of membranes (3). Particularly in the chloroplast membranes, it could be advantageous to regulate lipid composition in response to environmental changes because it is shown that functional activities of these membranes depend upon their physical state A set of experiments indicated that high temperature action induced changes dependent upon the resistance of plants, heat exposure, and humidity of soil and air (4, 5).
