It was shown that irradiation of callus with laser light at a dose of 3.6 J/cm<sup>2</sup> led to significant changes in the content of these components. Thus, the content of phosphatidylinositol increased in irradiated callus by 8 times, phosphatidylethonolamine by 2 times, the content of phosphatidic acid decreased by 20% of the sum of phospholipids. For sterols, it was established that irradiation caused the most significant changes in the content of β-sitosterol, which is dominant in plants (an increase from 1453 ± 170 μg/g of dry weight in the non-irradiated control to 2001 ± 112 μg/g of dry weight 1 h after exposure) and, due to this, in the total content of sterols. Analysis of the results obtained suggests that phospholipids and sterols, primarily those for which regulatory and signaling functions are known, are involved in the response of plant tissue to exposure to low-intensity laser radiation from a He-Ne laser. This participation is realized as a stressful (nonspecific) response to intense radiation.</p></abstract><trans-abstract xml:lang="ru"><p>Методами хроматомасс-спектрометрии и тонкослойной хроматографии изучено влияние облучения светом He-Ne-лазера на состав и содержание компонентов клеточных мембран в каллусных тканях пшеницы: фосфолипидов (ФЛ) и стеринов. Показано, что облучение каллусов светом лазера в дозе 3.6 Дж/см<sup>2</sup> приводило к значительным изменениям в содержании этих компонентов. Так, содержание фосфатидилинозита увеличилось в облученных каллусах в 8 раз, фосфатидилэтоноламина в 2 раза, содержание фосфатидной кислоты снизилось на 20% от суммы ФЛ. Для стеринов установлено, что наиболее существенные изменения облучение вызвало в содержании доминирующего в растениях β-ситостерина (увеличение с 1453±170 мкг/г сухого веса в необлученном контроле до 2001±111 мкг/г сухого веса через час после воздействия) и за счет этого в суммарном содержании стеринов. Анализ полученных результатов позволяет предположить, что ФЛ и стерины, в первую очередь те, для которых известны регуляторные и сигнальные функции, участвуют в реакции растительной ткани на воздействие низкоинтенсивным лазерным излучением He-Ne-лазера. Это участие реализуется как стрессовый (неспецифический) ответ на интенсивное излучение.</p></trans-abstract><kwd-group xml:lang="en"><kwd>phospholipids</kwd><kwd>sterols</kwd><kwd>He-Ne laser</kwd><kwd>callus tissues</kwd><kwd>Triticum aestivum L.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фосфолипиды</kwd><kwd>стерины</kwd><kwd>He-Ne-лазер</kwd><kwd>культура ткани</kwd><kwd>Triticum aestivum L.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kreslavski V.D., Carpentier R., Klimov V.V., Allakhverdiev S.I. 2009.
