Analyzed hravisensitive common species of deciduous mosses and selected 5 species for experimental studies of growth responses at different stages of ontogeny , depending on the force of gravity. Established that perpendicular vectors targeting low-intensity red light and gravity weakens forming branches on one side of the cell wall protonema Tortula modica, Ceratodon purpureus i Leptobryum pyriforme and, conversely , single vector effect of light and gravity stimulates branching on both sides. The angle of the lateral branches during the first cell division is regulated by the interaction of photo-and gravitropism . It is shown that the preservation of the memory cell information hraviinduktion genetically regulated at the level of transcription of DNA (methylation state of GC nucleotides ). Increasing hravivisensitived on hametofors stage in life are strategy arctic forms Bryum pseudotriquetrum, relatively high hravisensitive protonema moss samples Lviv is a manifestation of a mechanism to ensure growth and vegetative propagation of movements in stressed conditions short growing season in the Arctic. Determined that the change in the force of gravity is stressful factor that enhances the physiological antioxidant response of the kosmopolitan type - Bryum argenteum. Hravisensitive moss with a high growth rate and development Leptobryum pyriforme recommended as a model view object to determine the role of gravity in the development of mosses .
