Under the cold stress sugar content in transgenic plants was significantly lower than in non-transformed, however the proline content was higher. MDA content was increased in non-transgenic plants and was decreased in the transgenic. That the change in the activity of the SOD enzyme in the both lines of the plants was similar, and peroxidase activity for 2 days under cold stress in non-transgenic plants increased, remaining constant at the transgenic, but in 5 days decreased in both lines of plants. After the return of plants to +24 °C, all parameters in all plant lines returned to normal. According to the results of experiments suggests that the kind of protein content for expressing transgenic plants OSMYB4 affects the other genes, low and high expression.</abstract><trans-abstract xml:lang="ru">В статье представлены результаты изучения накопления сахаров, пролина и малонового диальдегида, а также активность ферментов супероксиддисмутазы (СОД) и пероксидазы в трансгенных растениях рапса (Brassica napus L.) с геном транс-фактора OsMyb4 риса и в нетрансформированных растениях. При действии холода содержание сахаров у трансгенных растений было значительно ниже, чем у нетрансформированных, однако содержание пролина у них было выше. Количество малонового альдегида (МДА) повышалось у нетрансформированных растений и понижалось у трансгенных. Активность СОД изменялась сходным образом у обеих линий растений, тогда как активность пероксидазы на 2-е сутки охлаждения у нетрансгенных растений увеличивалась, оставаясь постоянной у трансгенов, на 5-е сутки она уменьшалась у обеих линий растений. После возврата растений на +24 °С все показатели у всех линий растений возвращались к норме. По результатам опытов можно предположить, что экспрессирующийся трансфакторный белок OSMYB4 влияет на экспрессию других генов, ослабляя или усиливая ее.</trans-abstract><kwd-group xml:lang="en"><kwd>Brassica napus</kwd><kwd>OsMyb4</kwd><kwd>Brassica napus</kwd><kwd>rapeseed</kwd><kwd>transgenic plants</kwd><kwd>OsMyb4</kwd><kwd>transcription factor</kwd><kwd>cold tolerance</kwd><kwd>compatible osmolyte</kwd><kwd>enzymes of antioxidant system</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рапс</kwd><kwd>трансгенные растения</kwd><kwd>транскрипционный фактор</kwd><kwd>холодоустойчивость</kwd><kwd>совместимые осмолиты</kwd><kwd>ферменты антиоксидантной системы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Thomashow M.F.
