Anotace	Responses of antioxidant enzymes from leaves and roots of tobacco plants to the drought stress, salinity and enhanced zinc concentration were investigated. The transgenic plants (AtCKX2) exhibited highly enhanced CKX activity and decreased contents of cytokinins and abscisic acid in both leaves and roots, altered phenotype, retarded growth, and postponed senescence onset. Under control conditions, the AtCKX2 plants exhibited noticeably higher activity of GR in leaves and APX and SOD in roots. CAT activity in leaves always decreased upon stresses in WT while increased in AtCKX2 plants. On the contrary, SOD activity was enhanced in WT but declined in AtCKX2 leaves. In roots, APX activity prevailingly increased in WT while mainly decreased in AtCKX2 in response to stresses. Both WT and AtCKX2 leaves and roots exhibited elevated abscisic acid content and increased CKX activity under all stresses while endogenous CKs and IAA contents were not much affected by stress in either plants.
