The similarity of the inter-node dynamics of the ID1, DLF1, ZCN7 and ZCN8 gene expression was shown throughout the entire measurement period. It was determined that ~10 days before visual detection of the inflorescence meristem, the expression of the flowering activator genes ID1, DLF1, ZCN7 and ZCN8 significantly increased in the reproductive node compared to the adjacent nodes, while the flowering inhibitor gene ZCN6 expression decreased to trace values ​at all nodes.</p></abstract><trans-abstract xml:lang="ru"><p>Определен профиль экспрессии ключевых генов регуляции инициации цветения (ID1, DLF1, ZCN6, ZCN7, ZCN8) Zea mays L. в листовых пазухах репродуктивного и прилежащих ярусов в процессе зацветания растения. Показано сходство межъярусной динамики экспрессии генов ID1, DLF1, ZCN7 и ZCN8 на протяжении всего периода измерений. Определено, что за ~10 суток до визуальной регистрации меристемы соцветия-початка экспрессия генов активаторов цветения ID1, DLF1, ZCN7 и ZCN8 значительно повышается в репродуктивном ярусе в сравнении с ярусами, расположенными выше и ниже, тогда как экспрессия гена ингибитора цветения ZCN6 снижается до нулевых значений на всех ярусах.</p></trans-abstract><kwd-group xml:lang="en"><kwd>maize</kwd><kwd>Zea mays L.</kwd><kwd>inflorescence-ear</kwd><kwd>flowering initiation</kwd><kwd>florigen</kwd><kwd>gene expression</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кукуруза</kwd><kwd>Zea mays L.</kwd><kwd>соцветие-початок</kwd><kwd>инициация цветения</kwd><kwd>флориген</kwd><kwd>экспрессия генов</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке ФНТП развития сельского хозяйства РФ “Аграрная наука – шаг в будущее развитие АПК” (НИОКТР № 123082300022-3).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bortiri E., Hake S. // J.
