There are cases of increasing of nicotine content in transgenic tobacco roots expressing <italic>rolC</italic> alone or in combination with other <italic>rol</italic> genes. In this work, we evaluated the change in the expression of nicotine synthesis genes and their regulators in response to the induction of expression of <italic>rolC</italic>.</p> <p><bold>Materials and methods.</bold> Plant material was represented by three <italic>Nicotiana tabacum</italic> genotypes: cv. Samsun and two transgenic lines, derived from this cultivar and containing <italic>rolC</italic> under dexamethasone inducible promoter: <italic>A. rhizogenes rolC</italic> (Pdex-A4<italic>rolC</italic>) and <italic>N. tabacum rolC</italic> (Pdex-t<italic>rolC</italic>) correspondingly. Fluidigm Biomark RT-PCR was used for evaluation of expression of <italic>QPT1</italic>,<italic> QPT2</italic>,<italic> A622</italic>,<italic> ODC</italic>,<italic> ADC</italic>,<italic> PMT1</italic>,<italic> PMT2</italic>,<italic> PMT3</italic>,<italic> PMT4</italic>,<italic> MPO1</italic>,<italic> MPO2</italic>,<italic> BBL</italic>,<italic> MATE1</italic>,<italic> MATE2</italic>,<italic> ARF6</italic>,<italic> ERF168</italic>,<italic> ERF189</italic>, A4<italic>rolC</italic>, Nt<italic>rolC</italic>, and reference gene <italic>gapdh</italic>. HPLC-MS / MS analysis was used to determine content of nicotine and its derivatives in plant tissues.</p> <p><bold>Results.</bold> Expression of PMT genes for the synthesis of the pyrrolidine ring, as well as the genes, controlling enzyme for final stages of nicotine synthesis, was higher in transgenic lines without induction of <italic>rolC </italic>expression. Regulatory genes were activated by dexamethasone in both transgenic and control lines, indicating the inapplicability of <italic>rolC</italic> dexamethasone induction for their study. The level of expression of <italic>PMT</italic> and <italic>MPO</italic> genes increased over time in transgenic dexamethasone-induced lines. Nicotine content decreased in transgenic dexamethasone-induced plants.</p> <p><bold>Conclusions. </bold>The <italic>rolC</italic> gene does not play a primary role in the regulation of nicotine synthesis genes.

Описаны случаи увеличения содержания никотина в трансгенных корнях табака, экспрессирующих <italic>rolC</italic> отдельно или в комбинации с другими <italic>rol</italic>-генами. В этой работе мы оценили изменение экспрессии генов синтеза никотина и их регуляторов в ответ на индукцию экспрессии <italic>rolC</italic>. Растительный материал был представлен тремя генотипами <italic>Nicotiana tabacum</italic>: сорт Samsun и две трансгенные линии, полученные на основе этого сорта, и содержащие <italic>rolC</italic> под индуцируемым дексаметазоном промотором <italic>A rhizogenes rolC</italic> (Pdex-A4<italic>rolC</italic>) и <italic>N. tabacum rolC</italic> (Pdex-Nt<italic>rolC</italic>) соответственно. Систему ПЦР в реальном времени Fluidigm Biomark использовали для оценки экспрессии <italic>QPT1</italic>,<italic> QPT2</italic>,<italic> A622</italic>,<italic> ODC</italic>,<italic> ADC</italic>,<italic> PMT1</italic>,<italic> PMT2</italic>,<italic> PMT3</italic>,<italic> PMT4</italic>,<italic> MPO1</italic>,<italic> MPO2</italic>,<italic> BBL</italic>,<italic> MATE1</italic>,<italic> MATE2</italic>,<italic> ARF6</italic>,<italic> ERF168</italic>,<italic> ERF189</italic>, A4<italic>rolC</italic>, Nt<italic>rolC</italic> и контрольного гена <italic>gapdh</italic>. Анализ ВЭЖХ-МС/МС использовали для определения содержания никотина и его производных в растительных тканях. Экспрессия генов синтеза пирролидинового кольца <italic>РМТ</italic>, а также генов, контролирующих фермент конечной стадии синтеза никотина, была выше в трансгенных линиях без индукции экспрессии <italic>rolC</italic>. Регуляторные гены были активированы дексаметазоном как в трансгенных, так и в контрольных линиях, что указывает на неприменимость индукции <italic>rolC</italic> дексаметазоном для их исследования. В то же время уровень экспрессии генов <italic>PMT</italic> и <italic>MPO</italic> со временем повышался в трансгенных дексаметазон-индуцированных растениях, а содержание никотина снижалось. Таким образом, ген <italic>rolC</italic> не играет первостепенной роли в регуляции генов синтеза никотина. Механизм регуляции изученных генов неодинаков.</p></trans-abstract><kwd-group xml:lang="en"><kwd>nicotine production</kwd><kwd>gene expression</kwd><kwd>rolC</kwd><kwd>transgenic plants</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синтез никотина</kwd><kwd>экспрессия генов</kwd><kwd>rolC</kwd><kwd>трансгенные растения</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский Фонд Фундаментальных Исследований</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Researches</institution></institution-wrap></funding-source><award-id>18-016-00118</award-id></award-group><funding-statement xml:lang="en">RFBR</funding-statement><funding-statement xml:lang="ru">РФФИ</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>White FF, Garfinkel DJ, Huffman GA, et al.
