Засоление - один из важных факторов абиотического стресса, который ограничивает рост и продуктивность растений. Мутанты, принадлежащие поколению M2, определены как устойчивые к 90 мМ NaCl. Относительное содержание в белковых изолятах сои структур типа a-спирали, b-слоя, изгиба и нерегулярных конформаций определено по данным анализа в области амид I. Сравнение вторичных структур соевых белков мутантов со структурами контрольной группы показывает, что в результате солевого стресса доля структур типа a-спирали уменьшается, а количество неупорядоченных структур и b-изгиба возрастает. </p></abstract><trans-abstract xml:lang="en"><p>The effect of salinity on the conformation of proteins of four salt-tolerant M2 generation mutants of soybean plants (S04-05/150-2, S04-05/150-8, S04-05/150-106, and S04-05/150-114) was investigated using Fourier transform infrared (FTIR) spectroscopy. Salinity is one of the important abiotic stress factors that limits growth and productivity of plants. The mutants belonging to the M2 generation were determined as tolerant to 90 mM NaCl. The relative contents of a-helix, b-sheet, turn, and irregular conformations for the soybean protein isolates were determined depending on the analysis of the amide I region. The comparison of the secondary structures of soybean proteins of the mutants with those of the control group indicated that the a-helix structure percentage was diminished while b-turn and disordered structures were increased as a result of the salt stress. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>ИК спектроскопия</kwd><kwd>белковые изоляты сои</kwd><kwd>солеустойчивые мутанты</kwd><kwd>IR spectroscopy</kwd><kwd>soybean protein isolates</kwd><kwd>salt-tolerant mutants</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">C.
