“…Metals can also trigger a series of changes that can lead to phytotoxicity (Gratão et al 2009;Kopittke et al 2010;Lux et al 2011). Therefore, research into metal-induced plant stress is one of the most rapidly growing areas of agricultural research, which can be readily confirmed by the number of papers published weekly on this subject (Martinez-Penalver et al 2012;Mihucz et al 2012;Tian et al 2012).…”

Cadmium (Cd) is an important metal due to its industrial use but also one of the most dangerous metals because of its accumulation in the environment. This can eventually lead to entrance into the food chain if the Cd is taken up by crop plants used for feeding animals and humans. Thus, a large number of reviews have discussed the many aspects of stress induced by Cd and other metals in a wide range of species. In relation to plants, useful reviews have been published over the years regarding molecular and biochemical aspects of Cd stress. In this minireview, we have concentrated on promising and emerging topics of Cd‐stress research in plants, such as hormonal control of the antioxidant system and interaction between organisms and plants.

“…Heavy metal contamination of soils is a serious problem of the modern world (Mihucz et al 2012). Cadmium is recognized as one of the most toxic pollutant due to its high mobility and low amount needed to cause the toxicity symptoms.…”

“…Other mechanisms allowing species to endure Cd pollution include metal complexation by chelating agents or its compartmentalization (Sorrentino et al 2018). As cadmium causes oxidative stress (Mihucz et al 2012), an adequate antioxidative system reaction is also a fundamental cell defense mechanism. The activation of antioxidative enzymes helps to protect plant against oxidative injury evoked by heavy metals (DalCorso et al 2008).…”

The use of pedunculate oak (Quercus robur L.), along with other tree species, for the afforestation of heavy metal contaminated lands is an attractive prospect. Little, however, is known of Q. robur tolerance and its antioxidative system response to heavy metal exposure. The main objective of the study was to determine the cadmium-induced changes in antioxidative system of pedunculate oak in an attempt to identify molecular mechanisms underlying Cd tolerance. This may be of great importance in respect of using Q. robur for phytoremediation purposes. As the response of the antioxidative system to heavy metal contamination can vary within species, the research was conducted on oak seedlings from two different regions of origin. Differences in antioxidative system response of seedlings derived from tested regions of origin were noticed both at the transcript and enzyme activity levels. The obtained results indicate that ascorbate peroxidase (APX; EC 1.11.1.11) and superoxide dismutase (SOD; EC 1.15.1.1) play a first barrier role in oak seedlings response to the oxidative stress caused by Cd exposure. Catalase (CAT; EC 1.11.1.6) is involved in reducing the negative effects of prolonged Cd treatment.

The fields in which lead (Pb) finds application in the modern world have increased dramatically in recent years. As a consequence of this intensive utilization of Pb, its toxicity tends to pose more and more environmental problems. The aim of this study was to evaluate the genotoxic potential of Pb and to characterize some physiological parameters in Secale cereale under Pb stress. Plants were subjected to different exposure levels of Pb (0, 100, 200 and 400 mmol/L) for two weeks. At the end of the experimental period, the effects of Pb exposure on the photosynthetic pigments content (chlorophyll a and b, total chlorophyll, chlorophyll a/b and carotenoids) and genetic material of S. cereale were studied. To evaluate the genotoxic effect of Pb, random amplified polymorphic DNA À polymerase chain reaction (RAPD-PCR) was employed. The obtained results showed alteration in the photosynthetic pigments content and RAPD-PCR profiles of S. cereale grown in the presence of Pb. The alterations in the RAPD-PCR profiles following Pb treatments appeared to be losses of normal bands and occurrences of new bands compared to unexposed plantlets. Overall, the content of chlorophyll a, chlorophyll b, total chlorophyll and carotenoids decreased by 6.68%, 6.08%, 2.89% and 8.57%, respectively, under severe Pb stress (400 mmol/L).
