Заглавие : Toxic effects of the fungicide tebuconazole on the root system of fusarium-infected wheat plants
Место публикации : Plant Physiol. Biochem.: Elsevier Masson SAS, 2018. - Vol. 132. - С. 400-407. - ISSN 09819428 (ISSN) , DOI 10.1016/j.plaphy.2018.09.025
Ключевые слова (''Своб.индексиров.''): border cells--carbonylated proteins--free proline--fusarium--malondialdehyde--tebuconazole
Аннотация: The study investigates toxic effects of the fungicide tebuconazole (TEB) on Fusarium-infected wheat (Triticum aestivum) plants based on the morphological characteristics of root apices and changes in the integrated parameters of redox homeostasis, including the contents of free proline and products of peroxidation of proteins (carbonylated proteins, CP) and lipids (malondialdehyde, MDA) in roots. In two-day-old wheat sprouts infected by Fusarium graminearum, the levels of proline, CP, and border cells of root apices are higher than in roots of uninfected sprouts by a factor of 1.4, 8.0, and 3, respectively. The triazole fungicide tebuconazole (TEB) at the concentrations of 0.01, 0.10, and 1.00 ?g ml?1 of medium causes a dose-dependent decrease in the number of border cells. The study of the effects of TEB and fusarium infection on wheat plants in a 30-day experiment shows that the effect of the fungicide TEB on redox homeostasis in wheat roots varies depending on the plant growth stage and is significantly different in ecosystems with soil and plants infected by Fusarium phytopathogens. The study of the morphology of root apices shows that the toxic effects of TEB and fusarium infection are manifested in the destructive changes in root apices and the degradation of the root tip mantle. © 2018 Elsevier Masson SAS

Заглавие : Effects of PAR intensity and NaCl concentration on growth of Salicornia europaea plants as relevant to artificial ecological systems
Место публикации : Russ. J. Plant Physiol. - 2016. - Vol. 63, Is. 4. - С. 474-482. - ISSN 10214437 (ISSN) , DOI 10.1134/S1021443716040154
Ключевые слова (''Своб.индексиров.''): artificial ecosystems--co2 exchange--macroelements--mda--nacl salinity--par intensity--photosynthetic pigments--productivity--salicornia europaea
Аннотация: Effects of variable levels of photosynthetically active radiation (PAR) and NaCl concentrations, typical of closed ecological life support systems, on growth of Salicornia europaea L. plants, CO2 exchange, mineral composition, and the content of malondialdehyde (MDA) and photosynthetic pigments were investigated. The plants were grown for 25 days at different salinities of nutrient Knop solution (171, 342, and 513 mM NaCl) under two PAR levels (690 and 1150 ?mol/(m2 s)). At PAR of 690 ?mol/(m2 s), the plant productivity did not show significant changes at increasing salinities; at 1150 ?mol/(m2 s), the maximal productivity was observed at NaCl concentrations of 171 and 342 mM. The increase in NaCl concentration from 171 to 513 mM in the nutrient solution led to a substantial increase in the relative Na content in aboveground organs at PAR level of 1150 ?mol/(m2 s). The MDA content in aboveground organs by the end of the growth period was independent of PAR intensity. The content of photosynthetic pigments in the assimilatory tissue decreased with the increase in salinity from 342 to 513 mM NaCl at PAR level of 1150 ?mol/(m2 s) but not at the lower irradiance. The combination of 1150 ?mol/(m2 s) PAR intensity with the salinity as high as 342 mM NaCl was found to be the most effective for optimal productivity of S. europaea plants. © 2016, Pleiades Publishing, Ltd.

Аннотация: The integral bioluminescent biotest with lyophilized fluorescent bacteria was used for monitoring of LPO processes in tissue extracts and serum of rats exposed to stress. A relationship between the content of MDA (LPO indicator) and fluorescence of bacteria was observed in all biological samples.
