“…5a and 6e). These results agree with the findings of Piotrowska et al (2009) which state that JA application significantly inhibits Pb accumulation in W. arrhiza. In addition, other stress hormones, such as salicylic acid (SA), abscisic acid (ABA), and brassinolide (2,4-epibrassinolide), can reduce the uptake of toxic metals (Cd or nickel (Ni)) in hydroponic and soil-grown plants (Kanwar et al, 2012;Ali et al, 2015).…”

“…These results suggested that JA elicits protective effects during photosynthesis under Cd stress. Other studies demonstrated similar findings in JAand Pb-treated Wolffia arrhiza (Piotrowska et al, 2009) and soybean plants (Keramat et al, 2009). JA-induced protection of photosynthetic pigments can be attributed to the production of multiple secondary metabolite classes, alkaloids and phenolics, and anthocyanins in various plant species (Memelink et al, 2001).…”

Abstract:The well-known detrimental effects of cadmium (Cd) on plants are chloroplast destruction, photosynthetic pigment inhibition, imbalance of essential plant nutrients, and membrane damage. Jasmonic acid (JA) is an alleviator against different stresses such as salinity and drought. However, the functional attributes of JA in plants such as the interactive effects of JA application and Cd on rapeseed in response to heavy metal stress remain unclear. JA at 50 µmol/L was observed in literature to have senescence effects in plants. In the present study, 25 µmol/L JA is observed to be a "stress ameliorating molecule" by improving the tolerance of rapeseed plants to Cd toxicity. JA reduces the Cd uptake in the leaves, thereby reducing membrane damage and malondialdehyde content and increasing the essential nutrient uptake. Furthermore, JA shields the chloroplast against the damaging effects of Cd, thereby increasing gas exchange and photosynthetic pigments. Moreover, JA modulates the antioxidant enzyme activity to strengthen the internal defense system. Our results demonstrate the function of JA in alleviating Cd toxicity and its underlying mechanism. Moreover, JA attenuates the damage of Cd to plants. This study enriches our knowledge regarding the use of and protection provided by JA in Cd stress.

“…Plant biomass can also be restricted by high doses of lead exposure (Gopal and Rizvi 2008;Gichner et al 2008;Islam et al 2008;Piotrowska et al 2009;S i n g et al 2010). Under severe lead toxicity stress, plants displayed obvious symptoms of growth inhibition, with fewer, smaller, and more brittle leaves having dark purplish abaxial surfaces (Islam et al 2007;Gupta et al 2009).…”

“…The prominence of environmental lead contamination results both from its persistence Andra et al 2009;Punamiya et al 2010) and from its present and past numerous sources. These sources have included smelting, combustion of leaded gasoline, or applications of lead-contaminated media (sewage sludge and fertilizers) to land (Piotrowska et al 2009;Gupta et al 2009;Sammut et al 2010;Grover et al 2010). In 2009, production of recoverable lead from mining operations was 1690, 516, and 400 thousand metric tons by China, Australia, and the USA, respectively (USGS 2009).…”

“…As a known toxicant to plants, lead can induce phototoxic effects and inhibit the growth of aquatic plant, Lemnaceae Wolffia arrhiza (Piotrowska et al 2009). However, there could be hermetic effects in plants induced by low concentrations of lead, which have been confirmed by the stimulation of plant growth of Vicia faba (Wang et al 2010).…”

Lead (Pb) and zinc (Zn) are two typical metal contaminants with high levels in both seawater and sediment in the intertidal zones of the Bohai Sea. Suaeda salsa is the pioneer halophyte plant in the intertidal zones of the Bohai Sea. In the present work, the short (1 week) and long term (1 month) toxicological effects of environmentally relevant concentrations of Pb and Zn were characterized in S. salsa using NMR-based metabolomics combined with antioxidant enzyme activities. After metal exposure for 1 week, no significant metabolic responses were detected in root tissues of S. salsa. The significant metabolic responses included the increase of isocaproate, glucose and fructose, and decrease of malate, citrate and sucrose in root tissues of S. salsa exposed to Pb for 1 month. The increased phosphocholine and betaine, and decreased choline were uniquely found in Zn-exposed samples. The metabolic changes including decreased malate, citrate and sucrose were detected in both Pb and Zn-exposed groups. These metabolic biomarkers revealed that both Pb and Zn exposures could induce osmotic stress and disturbances in energy metabolism in S. salsa after exposures for 1 month. Overall, this work demonstrates that metabolomics can be used to elucidate toxicological effects of environmentally relevant metal contaminants using halophyte S. salsa as the bioindicator.
