Influence of brassinosteroids on plant cell alternative respiration pathway and antioxidant systems activity under abiotic stress conditions

Aim. To investigate the brassinosteroids (BRs) influence on the plant alternative respiration pathway and antioxidant systems to regulate the ROS (reactive oxygen species) production under optimal and abiotic stress conditions. Methods. Respiration measurement experiments were done with the polarogr...

Grabelnyh, O.I. Litvinovskaya, R.P. Voinikov, V.K. Sauchuk, A.L. Khripach, V.A. Kravets, V.S. Structure and Function of Biopolymers Aim. To investigate the brassinosteroids (BRs) influence on the plant alternative respiration pathway and antioxidant systems to regulate the ROS (reactive oxygen species) production under optimal and abiotic stress conditions. Methods. Respiration measurement experiments were done with the polarographic technique. Original methods were used to evaluate the antioxidant systems activity. Results. Treatment with BRs increased the inten- sity of plant alternative respiration pathway under control and stress conditions. BRs had no effect on alternative respiration of the BR-insensitive bri1–6 plants. Brassinosteroids also increased the activity of a range of antioxidant systems under osmotic stress. Conclusions. BRs are involved in the regulation of alternative respiration pathway and antioxidant systems activity in plant cells under optimal and abiotic stress conditions. Мета. Дослідити вплив брасиностероїдів (БС) на альтернативний шлях дихання рослин та антиоксидантні системи для регуляції процесів утворення активних форм кисню (АФК) за оптимальних і стресових умов. Методи. Інтенсивність дихання вимірювали методом полярографії. Активність антиоксидантних систем визначали оригінальними методами. Результати. Обробка БС підвищувала інтенсивність альтернативного шляху дихання рослин за оптимальних і стресових умов. БС не впливали на альтернативний шлях рослин bri1–6, нечутливих до дії БС. Брасиностероїди підвищували також активність низки антиоксидантних систем за умов осмотичного стресу. Висновки. БС залучені до регуляції альтернативного шляху дихання та активності антиоксидантних систем у клітинах рослин за контрольних умов та умов абіотичних стресів. Цель. Исследовать влияние брассиностеродиов (БС) на альтернативный путь дыхания растений и антиоксидантные системы для регуляции процессов образования активных форм кислорода (АФК) в оптимальных и стрессовых условиях. Методы. Интенсивность дыхания измеряли методом полярографии. Активность антиоксидантных систем определяли оригинальными методами. Результаты. Обработка БС повышала интенсивность альтернативного пути дыхания растений в контрольных и стрессовых условиях. БС не влияли на альтернативный путь дыхания растений bri1–6, нечувствительных к действию БС. Брассино-стероиды также повышали активность ряда антиоксидантных систем в условиях осмотического стресса. Выводы. БС вовлечены в регуляцию альтернативного пути дыхания и активности антиоксидантных систем клеток растений в контрольных условиях и в условиях абиотичесских стрессов. 2014 Article Influence of brassinosteroids on plant cell alternative respiration pathway and antioxidant systems activity under abiotic stress conditions / M.V.
