“…For all parameters except leaf weight, the decrease of the values under osmotic stress in compar ison to the control is insignificant. In the literature this variety is described as having high drought tolerance (Osipova et al, 2013), which is in agreement with our results.…”

Drought is one of the major environmental factors that limit crop growth and yield. Development of new wheat genotypes carrying introgressions from other cereal species is widely applied to improve the complex stability of bread wheat (Triticum aestivum L.). The aim of this study was to estimate the effect of alien genetic material (derived from Aegilops speltoides, Ae. tauschii, and T. timopheevii) on osmotic stress resistance in wheat seedlings. Indirect evaluation of drought resistance by creating an artificial shortage of moisture under laboratory conditions identified different degrees of the influence of alien genetic material. In particular, it was shown that the presence of the T6BS ⋅ 6BL 6SL translocation from the Ae. speltoides genome in bread wheat might increase its drought resistance, whereas the presence of a T. timopheevii intro gression in chromosome 2A, on the contrary, reduced the resistance of wheat to osmotic stress. By the exam ple of translocation T5BS ⋅ 5BL 5SL, it was found that the same alien fragment introgressed into different wheat genotypes could exert different effects on resistance to osmotic stress depending on the drought toler ance degree of the initial wheat genotype.

“…Based on our results and previous studies, these chromosomes are associated with wheat responses expressed by changes in CAT activity occurring during short- and long-term periods of water deficit. Moreover, Osipova et al [26] reported an increase in enzyme activity for lines 1A, 6A and 7B and no significant changes in lines 4A, 5A, 5B, 2B, 6B and 2D, which is consistent with the results of our study. Thus, we assume that prolonged osmotic stress treatment should not change the observed pattern of CAT activity for these lines.…”

“…A different pattern of CAT activity was observed for substitution lines 4A, 6A, 4B and 7D after long-term periods of water shortage relative to the recipient [26].

“…The alteration of the activities of APX, GPX, and CAT have been observed for Triticum aestivum under different environmental conditions (e.g., under cold temperatures [21], in the presence of zinc ions [22] and under drought conditions [13,23]). Many works report chromosomes associated with drought responses [24,25,26,27]. Most previous studies have been based on QTL analyses [28,29,30].…”

Water deficit induces reactive oxygen species (ROS) overproduction, which in turn inhibits plant growth and development. High concentrations of ROS disrupt the osmotic balance in plant cells and alter membrane integrity. Chromosomes carrying structural or regulatory genes must be detected to better understand plant response mechanisms to stress. The aim of our study was to identify Triticum aestivum L. chromosomes involved in early responses to short-term water-deficit stress (1, 3 and 6 h). In the present study, intervarietal substitution lines of drought-tolerant 'Saratovskaya 29' and sensitive 'Janetzkis Probat' wheat cultivars were examined. We studied the biochemical plant response system and conducted an analysis of catalase, ascorbate peroxidase and guaiacol peroxidase activities, levels of lipid peroxidation and changes in relative water content. Our results determined that the first reaction was a significant increase in guaiacol peroxidase (GPX) activity. However, the strongest impact on plant responses was found for catalase (CAT), which caused a significant decrease in lipid peroxidation (LPO) levels. Our findings indicate that chromosomes 5A, 4B, 6B and 7D are associated with early responses to short-term osmotic stress in wheat.

“…Many studies have focused on the development of varieties with increased drought resistance due to the importance of wheat in global cereal production and the worldwide problem of water deficits. The main purpose of such strategies is commonly the identification of genomic regions involved in the stress response 42,43 , although there is still no data concerning the initial plant reaction to water shortage. However, previous studies conducted with transcriptional or proteomic profiling indicate that the short-term plant response to stress factors can play important role in regulating gene expression and physiological responses, e.g., during hormone treatment 44 or salt stress 45 .…”

Water shortage is a major environmental stress that causes the generation of reactive oxygen species (ROS). The increase in ROS production induces molecular responses, which are key factors in determining the level of plant tolerance to stresses, including drought. The aim of this study was to determine the expression levels of genes encoding MAPKs ( MAPK3 and MAPK6 ), antioxidant enzymes ( CAT , APX and GPX ) and enzymes involved in proline biosynthesis ( P5CS and P5CR ) in Triticum aestivum L. seedlings in response to short-term drought conditions. A series of wheat intervarietal substitution lines (ISCSLs) obtained by the substitution of single chromosomes from a drought-sensitive cultivar into the genetic background of a drought-tolerant cultivar was used. This source material allowed the chromosomal localization of the genetic elements involved in the response to the analyzed stress factor (drought). The results indicated that the initial plant response to drought stress resulted notably in changes in the expression of MAPK6 and CAT and both the P5CS and P5CR genes. Our results showed that the substitution of chromosomes 3B, 5A, 7B and 7D had the greatest impact on the expression level of all tested genes, which indicates that they contain genetic elements that have a significant function in controlling tolerance to water deficits in the wheat genome.
