We analyzed phylogenetic reconstructions of charophytes (streptophyte) algae and assessed the importance of new phylogenetic hypotheses on some aspects of the evolution of plants. We give attention to the progress made in modern molecular biology study, and the occurrence of biological features and life cycles of organisms and multicellular gravitropism based on the results of molecular physiology and genome evolution. We analyzed generalized information on the significance and place of Сharophyta in the development of plants, how these plants were settled on land and their further development. We represent ideas about the modern interpretation of ancestral forms and consanguinity of this group of algae with other taxa of plants. We used a phylogenetic approach in analysis of formation and methods of cell division, with a deeper concept of complexity of the process of plant organization (the transition from unicellular to multicellular). We assessed evolutionary significance of the gravitropism phenomenon and some features of molecular and physiological changes in plant organisms during the change of environments and their outlet to the earth. Summarized and analyzed the changes in the modern paradigm in respect of group of streptophytes algae which can be assessed as a basis of other plants and close related to Zygnematales-line group of algae on the phylogenetic tree.

Паламарь-Мордвинцева Г.М., Царенко П.М., Баринова С.С. Филогенез, происхождение и родственные связи харофитовых водорослей. Представлены материалы анализа филогенетических реконструкций харофитовых водорослей, а также освещена значимость новых филогенетических гипотез о некоторых аспектах эволюции растений, с учетом современного прогресса в их молекулярно-биологическом изучении, раскрытии особенностей биологии жизненных циклов и развития организмов, возникновении многоклеточности и гравитропизма, с учетом результатов молекулярной физиологии и эволюции генома. Обобщены данные о формировании представлений о значимости харофитов в становлении мира растений, заселении ими суши и дальнейшего их развития. Обсуждается современная трактовка анцестральных форм и родственных связях этой группы водорослей с другими таксонами растительного мира. С использованием филогенетического подхода показаны особенности формирования и деления клетки, а также особенности процесса усложнения растительной организации (переход от одноклеточности к многоклеточности) и молекулярно-физиологических изменений растительных организмов в период смены среды обитания и выхода их на сушу. Обобщены и проанализированы материалы относительно смены или модификации современной парадигмы о близкородственной группе стрептофитовых водорослей к базису других растений и родственной сестринской линии Zygnematales на филогенетическом древе.
