У растений этот путь консервативен, но для разных видов наблюдается различное количество паралогов ферментов,участвующих в этом пути. В настоящей работе исследована возможная роль изменения числа паралогов ПБТ в процессе эволюции. Для этого проведена идентификация паралогов ферментов этого пути в известных полногеномных последовательностях и оценена статистическая связь между числом паралогов ПБТ и сложностью организмов. Показано, что сложность организмов достоверно коррелирует с числом гомологов ферментов синтеза триптофана у растений как для всех гомологов ферментов этого пути суммарно, так и для гомологов трех из шести ферментов этого пути ASA/ASB, PAI и IGPS. Выявленные зависимости могут быть обусловлены тем, что рост сложности организации растений и увеличение числа гомологов ферментов синтеза триптофана являются механизмами эволюционной адаптации к изменчивым условиям наземной среды обитания.</p></abstract><trans-abstract xml:lang="en"><p>The tryptophan biosynthesis pathway (TBP) is ubiquitous in most known organisms, being absent only from animals and some bacteria. It is conserved in plants, although various species differ in the number of TBP enzyme paralogs. In the current work we investigated a putative possible role of changes in the number of paralogs of TBP enzymes in the course of plant evolution. We identified TBP enzyme paralogs in plant species with fully sequenced genomes and estimated the relationship between its number and organismal complexity. It is shown that organismal complexity significantly correlates with the total number of TBP paralogs and for some enzymes specifically (ASA/ASB, PAI, and IGPS). We suggest that such a relationship arises because both organismal complexity and the increasing number of paralogs may be important for the evolutionary adaptation of land plants to variable environmental conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>путь биосинтеза триптофана</kwd><kwd>филогенетические сети</kwd><kwd>морфологическая сложность организмов</kwd><kwd>адаптация</kwd><kwd>изменчивость внешних условий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tryptophan biosynthesis pathway</kwd><kwd>phylogenetic network</kwd><kwd>morphological complexity of organisms</kwd><kwd>adaptation</kwd><kwd>variability of environmental conditions</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>РНФ</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Картель Н.А., Макеева Е.Н., Мезенко А.М.
