In an earlier work using tissue printing method, we found that the PR-10 stress protein was observed in leaf petiole of lupin seedling where lead was not detected (Przymusiński et al. 2001). These results suggested the presence of substance(s) mediating a signal transduction from directly affected cells to distant organs. As the hydrogen peroxide was found to be involved in signal transduction pathway, in the present paper, we analysed the level of H₂O₂ in the organ of lupin seedlings exposed to Pb²⁺ with spectrophotometric method and tissue printing technique. It was unequivocally demonstrated that the level of H₂O₂ and the activity of peroxidase increased in every tested organ of lead-treated lupin seedling. Both the level of H₂O₂ and the activity of POX were correlated with amount of Pb²⁺ ions in the cells (Przymusiński et al. 2001) and decreased in tissues more and more distant from the site of metal application. On the other hand, there was no correlation between the histological localization of H₂O₂ and peroxidase. Our results seem to confirm the hypothesis that H₂O₂ may act as a signalling substance involved in the induction of PR protein synthesis. It was indicated that there is high degree of correlation between the localization of H₂O₂ and the histological localization of PR-10 proteins (Przymusiński et al. 2001) in every tested organ of lupin seedling. The presented hypothesis is also supported by the fact that H₂O₂ and PR-10 proteins are detected in organs and tissues where Pb²⁺ was not found at all.

Previously, a stable cell suspension of cucumber tolerant to 100 µM CdCl2 was obtained (Gzyl & Gwóźdź, 2005, Plant Cell Tissue Organ Cult 80: 59-67). In this study, the relationship between the activity of antioxidant enzymes and cadmium tolerance of cucumber cells was analyzed. A cadmium-sensitive and the cadmium-tolerant cell lines were exposed to 100 µM and 200 µM CdCl2 and the activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APOX) and guaiacol peroxidase (POX) were determined. In the sensitive cell line, a decrease of total activity of SOD and POX was observed, whereas the activity of CAT and APOX significantly increased in metal-supplemented medium. By contrast, in the tolerant cells, the total activity of antioxidant enzymes decreased (SOD, CAT) or was maintained at approximately the same level (APOX, POX). Moreover, a different pattern of isoenzyme activity was observed in the tolerant and sensitive cells. These results suggest that an enhanced activity of antioxidant enzymes is not directly involved in the increased tolerance to cadmium of the selected cucumber cell line.
