Линии и формы пшеницы с измененной морфологией соцветия являются важным генетическим ресурсом как для изучения генетических механизмов, лежащих в основе программ развития растений и определяющих их архитектуру, так и для практического использования с целью повышения урожайности. В норме у пшеницы колоски располагаются двумя параллельными рядами вдоль оси колоса, формируя двурядный колос. Линии нестандартного морфотипа SCR (screwed spike rachis) мягкой пшеницы характеризуются спиральным расположением колосков вдоль колосового стержня. Изучение ранних этапов развития соцветия SCR-линий с использованием световой и сканирующей электронной микроскопии показало, что спиральное расположение колосков не связано с изменениями или нарушениями на ранних этапах развития соцветия при закладке и дифференцировке меристем соцветия и формировании органов соцветия, а является следствием особенностей роста клеток колосового стержня на более поздних этапах роста колоса. Таким образом, обнаружено, что спиральное расположение колосков в соцветии злаков может быть обусловлено особенностями не только закладки и взаимного расположения колосковых меристем соцветия (типом филлотаксиса соцветия), но и роста клеток на более поздних этапах роста соцветия. Показано, что признак SCR наследуется как доминантный моногенный. На проявление признака может влиять генотипическая среда. Линии морфотипа SCR, охарактеризованные с применением световой и сканирующей электронной микроскопии, представляют собой важный генетический ресурс для дальнейшего изучения молекулярно-генетических механизмов, определяющих архитектуру колоса. Кроме того, они могут быть использованы при создании линий и сортов пшеницы с новыми типами колоса, например, сочетание SCR и многоколосковости может обеспечить больше пространства и освещенности для развивающихся колосков в составе кластера из множества колосков.</p></abstract><trans-abstract xml:lang="en"><p>Features of wheat (Triticum aestivum L.) inflorescence development define its architecture and have an impact on yield potential. Wheat lines and forms with altered inflorescence morphology are important genetic resources for the study on the genetic mechanisms underlying plant developmental programs and inflorescence architecture; they are also important for practical use to increase productivity. Normally, wheat spikelets are arranged in two parallel rows along the spike axis. The SCR (screwed spike rachis) lines represent a non-standard morphotype, which is characterized by a spiral arrangement of spikelets along the spiked rachis. The study of the early stages of the inflorescence development in SCR-lines using light and scanning electron microscopy revealed that the spiral arrangement of spikelets were not related to changes at the early stage of inflorescence development, and resulted from spiral growth of spike rachis cells at later stages of spike growth. Thus, the spiral arrangement of spikelets in cereal inflorescence may have resulted not only from peculiarities of the mutual arrangement of spikelet meristems (phyllotaxis), but also from cell growth features at later stages of inflorescence growth. It was shown that SCR is inherited as a dominant monogenic trait; its expression can be modified by genotypic background. The SCR-lines characterized using light and scanning electron microscopy represent an important genetic resource for further study of the molecular-genetic mechanisms determining plant architecture. Furthermore, they can be used to develop wheat lines and cultivars with new inflorescence phenotypes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мягкая пшеница</kwd><kwd>Triticum aestivum L.</kwd><kwd>развитие соцветия</kwd><kwd>филлотаксис</kwd><kwd>сканирующая электронная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bread wheat</kwd><kwd>Triticum aestivum L.</kwd><kwd>inflorescence development</kwd><kwd>phyllotaxis</kwd><kwd>scanning electron microscopy</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>State Budgeted Project 03242016-0001, Russian Foundation for Basic Research, Ministry of Agriculture, Czech Republic</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">Babb S., Muehlbauer G.J.
