A sequence encoding MYB114 TF was found to be the closest in a nucleotide structure to the previously investigated genes in Solanaceae. Primers were selected and a comparative analysis of <italic>Myb114</italic> gene sequences was performed in <italic>B. oleracea</italic> varieties (white cabbage, red cabbage, kale, cauliflower, broccoli, and kohlrabi) with a wide intraspecies diversity by the anthocyanin accumulation in leaves and various food organs: heads, curds and stems. Alignment of <italic>Myb114</italic> sequences revealed a number of gene polymorphisms that closely correlate with high anthocyanin accumulation in <italic>B. oleracea</italic> leaves, including 3 SNPs in exon regions and a 271 bp deletion in the 1st intron. The identified SNPs lead to the replacement of two amino acids located in the region of DNA-binding domains, which leads to a change in the binding efficiency of this transcription factor with the promoters of structural biosynthesis genes and a decrease in their expression level in the forms without anthocyanin accumulation in leaves compared with the forms with their accumulation in vegetative plant parts. A molecular marker MYB114.2 has been proposed that may be used for the identification of headed cabbages and kales with high/low anthocyanin accumulation. By the amino acid structure and phenotypic manifestation (regulation of anthocyanin accumulation in leaves), <italic>Myb114 B. oleracea</italic> is the closest to <italic>Ant2</italic> tomato, <italic>Myb2</italic> eggplant and <italic>Myb113-like2</italic> pepper alleles. A high degree of conservatism of the SANT DNA-binding domains of MYB114 TF of <italic>B. oleracea</italic> and R2R3-MYB TF of nightshades was established.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324327984">С целью изучения механизма регуляции одного из древнейших у растений процессов биосинтеза антоцианов, на основе сравнения генов R2R3-MYB транскрипционных факторов (ТФ) у пасленовых (<italic>S. lycopersicum</italic>:<italic> An1</italic>, <italic>An2</italic>; <italic>S. melongena</italic>:<italic> Myb1</italic>; <italic>C. annuum</italic>:<italic> Myb113-like1</italic> и <italic>Myb113-like2</italic>) и капустных культур выполнен поиск ортологичных последовательностей у <italic>Brassica oleracea</italic>. Выявлена наиболее близкая по нуклеотидной структуре к ранее изученным генам у пасленовых последовательность, кодирующая MYB114 ТФ. Подобраны праймеры и выполнен сравнительный анализ последовательностей гена <italic>Myb114</italic> у овощных культур <italic>B. oleracea</italic> (разновидности капуста белокочанная, краснокочанная, листовая, цветная, брокколи, кольраби) с широким внутривидовым разнообразием по накоплению антоцианов в листьях и различных продуктовых органах – кочанах, головках (соцветиях) и стеблеплодах. По результатам выравнивания последовательностей <italic>Myb114</italic> выявлен ряд однонуклеотидных замен, тесно коррелирующих с высоким накоплением антоцианов в листьях <italic>B. oleracea,</italic> включающих 3 SNP в экзонных областях и делецию в первом интроне размером 271 пн. Выявленные SNP ведут к замене двух аминокислот, расположенных в области ДНК-связывающих доменов, что приводит к изменению эффективности связывания данного транскрипционного фактора с промоторами структурных генов биосинтеза и снижению уровня их экспрессии у форм без антоциана в листьях по сравнению с формами с его накоплением в вегетативных частях растений. Предложен молекулярный маркер MYB114.2, который может быть использован для идентификации кочанных и листовых капуст с высоким/низким накоплением антоцианов. По аминокислотной структуре и фенотипическому проявлению (регуляция накопления антоцианов в листьях) <italic>Myb114 B. oleracea</italic> наиболее близок к аллелям <italic>Ant2</italic> томата, <italic>Myb2</italic> баклажана и <italic>Myb113-like2</italic> перца.
