В результате анализа полной нуклеотидной последовательности бактерий P. megaterium БИМ B-1314Д установлено, что геном штамма P. megaterium БИМ В‑1314Д представлен одной кольцевой хромосомой и девятью плазмидами. Последовательность генома депонирована в ГенБанк НЦБИ под номерами CP058262–CP058271. Геном штамма P. megaterium БИМ B-1314Д имеет размер 5 984 922 пары оснований со средним содержанием ГЦ-пар 37,7 % и содержит 6 187 открытых рамок считывания, из них 5 978 аннотированы как кодирующие белки, 92 – как псевдогены, 154 – как гены тРНК, 8 – как гены нкРНК и 47 – как гены рРНК. В геноме идентифицированы гены, вероятно ответственные за синтез и транспорт осмолитов бетаина и пролина, транспорт ионов калия, что, предположительно, и обеспечивает адаптацию штамма P. megaterium БИМ B-1314Д к осмотическому стрессу. Определены генетические локусы, продукты которых могут участвовать в синтезе фитогормонов и полиаминов, которые, возможно, и обусловливают ростостимулирующую способность изучаемого штамма. В геноме идентифицированы кластеры генов, предположительно детерминирующие синтез вторичных метаболитов, белков холодового и теплового шока, определена локализация генов, связанных с устойчивостью к окислительному стрессу. Данные анализа генома штамма P. megaterium БИМ B-1314Д представляют ценную информацию для дальнейшего изучения возможности применения штамма P. megaterium БИМ B-1314Д для стимуляции роста растений в условиях засоления.</p></abstract><trans-abstract xml:lang="en"><p>Priestia megaterium BIM В‑1314D is a halotolerant strain able to adapt to osmotic stress. The analysis of a full nucleotide sequence of bacterium P. megaterium BIM В‑1314D has revealed that the genome of the studied strain is represented by one circular chromosome and nine plasmids, deposited in the database of GenBank NCBI under the registration number CP058262–CP058271. The size of the bacterial genome constitutes 5 984 922 base pairs with an average GC content of 37.7 %. The genome contains 6 187 genes where 5 978 were annotated as protein-enconding, 92 – as pseudogenes, 154 – as tRNA genes, 8 – as ncRNA, 47 – as rRNA. The genes responsible for synthesis and transport of betaine and proline osmolytes and transport of potassium ions ensuring the adaptation of strain P. megaterium BIM В‑1314D to osmotic stress were local-ized in the genome. Gene loci were defined encoding production of metabolites involved in the synthesis of phytohormones and polyamines accounting for the growth-promoting microbial ability. Gene clusters determining the synthesis of secondary metabolites, cold and heat shock proteins were revealed in the genome. The genome analysis of strain P. megaterium BIM В‑1314D provides the valuable data on the bacterial culture for stimulation of the plant growth in the salinized conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Priestia</kwd><kwd>фитогормоны</kwd><kwd>галотолерантность</kwd><kwd>осмолиты</kwd><kwd>ростостимуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Priestia</kwd><kwd>phytohormones</kwd><kwd>halotolerance</kwd><kwd>osmolytes</kwd><kwd>growth stimulation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кошелева, Н.
