Respiratory supercomplexes are large protein structures formed by various enzyme complexes of the mitochondrial electron transport chain. Using native gel electrophoresis and activity staining, differential regulation of complex activity within the supercomplexes was investigated. During prolonged hypoxia, complex I activity within supercomplexes(More)
The costs of adaptation respiration, the contribution of different biochemical pathways of respiration and alternative oxidases to the adaptation to mineral deficiency were compared in plant species representing different types of adaptive strategies: ruderal (Ru) (Amaranthus retroflexus L. and Leonurus quinquelobatus Gilib.) and predominantly(More)
Growth parameters, the content of proline and flavonoids. Na+ and K+ ion accumulation in the shoots of four species of halophytes from the family Chenopodiaceae inhabiting the territory of the South Urals at different levels of salinity were studied. Within a single taxonomic group, different strategies of salt tolerance related to the level of soil(More)
In the roots of bread wheat (Triticum aestivum L.) seedlings, the effects of pretreatment with 28 nM wheat germ agglutinin (WGA) and successive action of 1 mM cadmium acetate on growth, phytohormone balance, lignin deposition, and also cadmium accumulation and distribution were studied. Priority data on cadmium-induced ABA-mediated reversible accumulation(More)
We studied the effects of wheat (Triticum aestivum L.) seed presowing treatment with 0.05 mM salicylic acid (SA) on its endogenous content and the ratio of free to bound forms in seedling shoots and roots. During two-week-long seedling growth, we observed a gradual decrease in the total SA content in shoots but not in roots. In shoots, the content of(More)
Transgenic tobacco (Nicotiana tabacum L. plants, cv. Samsun) bearing the gene for soybean (Glycine max (L.) Merr.) leghemoglobin A under the control of 35S CaMV promoter were produced. The effects of this gene expression on tobacco growth and respiration, MDA content, and also activities of catalase and guaicol peroxidase were studied. The growth rate of(More)
