Показано, что АЛК в концентрациях 20, 40 и 80 мг/л увеличивала длину проростков, уширяла листовую пластинку растений, подвергнутых действию 150 мМ NaCl, по сравнению с контрольными растениями, не обработанными АЛК. В присутствии индуктора НР – ее субстрата 20 мМ KNO3, экзогенная АЛК стимулировала экспрессию Nar 1 гена фермента, увеличивала содержание НР-белка и его активность в растениях, выращенных на 150 мМ NaCl. АЛК также индуцировала накопление свободного пролина и уменьшала способность растений генерировать супероксид анион-радикал. Таким образом, продемонстрировано, что наблюдаемые эффекты экзогенной АЛК на выращиваемые в условиях солевого стресса растения ячменя связаны со стимуляцией активности НР как на транскрипционном, так и на трансляционном уровнях и приводят к улучшению ростовых характеристик растений и повышению уровня антирадикальной защиты.</p></abstract><trans-abstract xml:lang="en"><p>The effect of exogenous 5-aminolevulinic acid (ALA) on the growth and activity of nitrate reductase (NR, EC 1.6.6.1), the synthesis of proline and the superoxide anion radical generation in barley (Hordeum vulgare L. cv. Gonar) seedlings grown under salinization with NaCl has been studied. The obtained data indicated that ALA (20, 40 and 80 mg L–1) increased the elongation and leaf blade expansion of barley seedlings exposed to 150 mM NaCl as compared to control plants, which were not treated with ALA. In the presence of the NR inductor – its substrate 20mM KNO3, exogenous ALA stimulated NR gene Nar 1 expression, increased the NR-protein content and enzymatic activities in plants grown in 150 mM NaCl solution. ALA also induced the accumulation of free proline and decreased the generation of superoxide anion radicals. Thus, this study demonstrates that ALA effects on salt-stressed barley seedlings involves the stimulation of NR activities both at transcriptional and translational levels and leads to complex physiological modifications, such as the improvements of plant growth and antiradical defense.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>засоление</kwd><kwd>Hordeum vulgare</kwd><kwd>нитратредуктаза</kwd><kwd>5-аминолевулиновая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>salinization</kwd><kwd>Hordeum vulgare</kwd><kwd>nitratereductase</kwd><kwd>5-aminolevulinic acid</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">Garg, S.
