Kholodny Institute of Botany NASU popup.description2 Climatic changes and global warming challenge the agricultural industry and require the new stable crops establishment. One of the successful steps taken to obtain such plants is the investigation and comprehension of the nature of cell adaptation processes. Changes in the pigment content and activity of lipoxygenase isoforms were found to correlate with the thermal resistance feature of winter wheat varieties. This enables to regard them as potential biomarkers for biotechnical developments to improve stress resistance of crops. The effect of transitional increase of nitric oxide content in roots of plantlets was established at their treatment with jasmonic (JA) and salicylic (SA) acids, which one was removed by the action of antioxidant dimethylthiourea (DMTU) and consequently was dependent on the formation of reactive oxygen species. NO and hydrogen peroxide play the role in the processes of JA- and SA-induced development of heat resistance of wheat plantlets. The distinctions in contribution of low-molecular protective compounds (proline, carbohydrates, anthocyans and flavonoids) in the adaptation to salt stress of Arabidopsis plants of wild­type, mutants on the jasmonate signalling (jin1) and transformants by the gene of bacterial salicylate hydroxylase (NahG) were shown.
