The results of complex studies of vegetative organs of plants of different ecology (true aquatic (Hydrocharis morsus-ranae), aerial-aquatic (Hydrocotyle leucocephala, Phragmites australis) terrestrial (Galanthus nivalis, Vinca minor, a model object Arabidopsis thaliana) in different environmental and experimental conditions, as well as the impact of piracetam on the growth of the Chlamydomonas reinhardtii accumulative culture in optimal and stressful conditions using modern methods of light and confocal microscopy, cytochemistry, biochemistry, molecular biology and statistics are presented. High phenotypic plasticity of structural, physiological and biochemical features, level of transcription and translation under changes in water regime, temperature and light intensity in nature and experiment has been established. It is shown that induction of HSP70 synthesis is the first reaction to the action of opposite stressors – flooding and drought, and its level is a sign of the plant resistance range. Adaptive changes of the photosynthetic apparatus in leaves of H. morsus-ranae during growth in shady conditions were revealed. H. verticillata is characterized as a model aerial-aquatic plant with a wide range of resistance to study the processes of adaptation to flooding. Give an idea of the participation of cyanide-resistant respiration in thermoregulatory processes of thermogenic plants. It was found that γ-aminobutyric acid is twice as effective as β-aminobutyric acid stimulates the growth of autotrophic cultures of C. reinhardtii. The question of the DNA methylation role in adaptive phenotypic plasticity of plants is considered and the prospects of research of Ukrainian flora species in this direction are outlined. The implementation of the project is directly related to the development of criteria for assessing the resistance of plants to environment adverse changes, without which it is impossible to predict the state of natural vegetation in global climate changes.
