Bioaccumulation and effect of cadmium in the photosynthetic apparatus of Prosopis juliflora

Growing, physiological responses and Cd uptake of Corn (Zea mays L.) under different Cd supply

“…Dried leaf samples were ground by mortar and pestle, and other plant tissues were ground in a rotary (Wiley) mill to pass a 40-mesh (0.5 mm) screen. After grinding, portions of all plant tissues were ashed in a muffle furnace at 500 °C for 18 h, and the resulting ash was dissolved in 10 ml of concentrated HNO 3 and diluted to a final volume of 50 ml with distilled water. These digested samples were the basis for the determination of Cd in plant tissues.…”

“…Cd contamination of agricultural soil has been becoming a serious environmental concern. Cadmium is a non-essential metal for crops, can be extremely toxic and characteristically causing growth inhibition, chlorophyll breakdown, leaf chlorosis and browning of root, Excessive Cd uptake by plants effected essential physiological process, induced oxidating stress and caused damage in plants by increasing the production of reactive oxygen species and lipid peroxidation [2][3][4][5][6]. Cd ecotoxicity induced low biomass of crops compensated by very high metal concentrations in the shoots and roots [7][8][9][10].…”

Effect of Cadmium Toxicity on Growth, Oxidative Damage, Antioxidant Defense System and Cadmium Accumulation in Two Sorghum Cultivars

“…Due to advancements in agricultural and industrial sectors, serious attention has been given to issues related to Cd toxicity in the past few decades [ 13 ]. Cd presence in excessive amounts (≥1 mM) in the soil is detrimental for plants, resulting in hazardous effects on many physiological processes, including growth inhibition, root browning, chlorophyll degradation and chlorosis of leaves [ 14 , 15 , 16 , 17 , 18 ]. Cd toxicity results from the increased concentration of Cd ions in both roots and shoots, thus decreasing the crop biomass [ 19 , 20 , 21 , 22 ].…”

Effect of cadmium on young plants of Virola surinamensis

“…The reduction in chlorophyll content by increased degradation or decreased biosynthesis may have been reflected in significant reductions in photosynthetic activity of plants under stress by Cd (Elloumi et al 2014; Hernández et al 2015; Yang et al 2015; Michel-López et al 2016; Zouari et al 2016; Nikolić et al 2017; Silva et al 2017).…”

“…The symptoms of phytotoxicity by Cd in plants include a modification in the indices of chlorophyll a , b and total, resulting in significant reductions in photosynthetic activity (Elloumi et al 2014; Hernández et al 2015; Yang et al 2015; Michel-López et al 2016; Zouari et al 2016; Nikolić et al 2017; Silva et al 2017), especially due to the inhibition of photosystem II (PSII) (Di Baccio et al 2014) by changing the potential yield of the photochemical reaction ( Fv/Fm ) (Fernández et al 2013; Yang et al 2015; Solti et al 2016) and CO 2 -fixing key enzymes, such as ribulose-1,5-bisphosphate carboxylase (RuBisCO) (Tran and Popova 2013). In addition, Cd in plants affects the water relations, respiration (Oláh et al 2015), transpiration, stomatal conductance and intercellular CO 2 concentration (Elloumi et al 2014; Song et al 2016; Zouari et al 2016; Nikolić et al 2017).…”
