A number of morphological, physiological and phenological traits have been suggested as significant markers of adaptation to drought in bread wheat (Triticum aestivum L.). This study was aimed at the identification of a relationship between dehydroascorbate reductase (DHAR, EC 1.8.5.1) and catalase (CAT, EC 1.11.1.6) activities in leaves of wheat plants and(More)
Understanding of the genetic basis of physiological properties, which are most relevant to water-deficit tolerance would be helpful for genomic-assisted improvement of bread wheat. A set of bread wheat inter-varietal single chromosome substitution lines (ISCSLs) of variety ‘Janetzkis Probat’ (JP) in the genetic background of ‘Saratovskaya’ 29 (S29) were(More)
Optically active bis-2R(–)ethylhexyl o-phthalate was obtained with 0.18% yield from dry cultured cells of Aconitum baicalense Turcz ex Rapaics 1907 by extraction with petroleum ether followed by silica gel column chromatography. Its structure was confirmed by the analysis of 13C and 1H NMR spectra. Seasonal fluctuations of quantitative phthalate content in(More)
The various enzyme systems and low molecular weight (LMW) redox agents are related to the folding and polymerization of prolamins in the ripening wheat grains and the formation of baking quality. Protein disulfide isomerases (PDIs) and cyclophylins accelerate "correct" folding of prolamins, which is most likely necessary for the subsequent formation of the(More)
The effects of intercultivar substitution of individual chromosome pairs (except for 1B, 6D, and 7A) in the wheat cultivars Saratovskaya 29 and Janetzkis Probat, differing in quality, on specific lipoxygenase activity, the grain yield per spike, and the main technological properties of flour and dough were studied. It was demonstrated that the substitution(More)
Lipoxygenase (LOG) in protein fractions isolated from the leaves of substituted wheat lines was investigated. Three molecular forms of the enzyme were detected. A water deficiency caused the induction of a membrane-bound form (mLOG) and resulted in a decrease in the activity of “soluble” enzymes (s1LOG) and (s2LOG) in most genotypes. A correlation analysis(More)
The changes in the contents of protein and free amino acids in pea plants inoculated with Rhizobium leguminosarum were studied taking into account the susceptibility of roots to root nodule bacteria. The content of cytoplasmic protein during infection increased in the actively growing root zone (0–5 mm) and decreased in the root zones susceptible to(More)
Alien hybridization in cereals is used for the comparative investigation of the genome structure and evolution, as well as for extracting useful genes from the wild gene pool. The tetraploid species Triticum timopheevii has long been used as a source of genes for resistance to fungal diseases. Line 821 was developed on the genetic background of cultivar(More)
Quantitative trait loci (QTLs) associated with the phenotypic expression of the activity of different forms of lipoxygenase (LOX) under water deficit were detected in the chromosomes of the D-genome using intogression lines of common wheat Triticum aestivum L. Chinese Spring (Synthetic 6x). QTL associated with the activity of seed soluble LOX was identified(More)
Activities of oxygen-dependent thiol: O2 oxidoreductase (EC 1.8.3.2) and glutathione-dependent thiol: protein-disulfide oxidoreductase (EC 1.8.4.2) as well as technological value of seven soft spring wheat cultivars grown on different soil under contrasting climatic conditions (Krasnodar krai and Irkutsk oblast) were studied. It was found that the ratio of(More)
