Description	Drought tolerance of plants is a complex character, therefore, the assessment is considerably difficult. It is most often evaluated by using physiological and morphological methods, which make the assessment of mechanisms in plants that lead to their resistance possible. The intensity of plant cell protective mechanisms can be evaluated on the molecular level. In our work, the stress response was evaluated by relative water content (RWC), osmotic oressure (OP) and the relative expression of WDHN13 and WRAB17 genes from the COR/LEA group. The evaluation included 3 varieties of winter wheat grown in the Czech Republic and one Syrian line potentially highly resistant to drought. The varieties were at the same time compared for differences in the root system size by means of specific root length (SRL). The obtained results clearly indicated a relation between the expressions of both genes and the tissue water content; RWC reduction was strongly connected with changes in the genes' activity. Particularly the expression of WDHN13 in variety Meritto increased although the tissue hydration level was only slightly reduced, which can be related to the good adaptability of this genotype to stress.
