Copper is a mineral element essential for the normal growth and development of plants; however, excessive levels can severely affect plant growth and development. Oryza sativa L. multiple stress-responsive gene 3 (OsMSR3) is a small, low-molecular-weight heat shock protein (HSP) gene. A previous study has shown that OsMSR3 expression improves the tolerance of Arabidopsis to cadmium stress. However, the role of OsMSR3 in the Cu stress response of plants remains unclear, and, thus, this study aimed to elucidate this phenomenon in Arabidopsis thaliana, to further understand the role of small HSPs (sHSPs) in heavy metal resistance in plants. Under Cu stress, transgenic A. thaliana expressing OsMSR3 showed higher tolerance to Cu, longer roots, higher survival rates, biomass, and relative water content, and accumulated more Cu, abscisic acid (ABA), hydrogen peroxide, chlorophyll, carotenoid, superoxide dismutase, and peroxidase than wild-type plants did. Moreover, OsMSR3 expression in A. thaliana increased the expression of antioxidant-related and ABA-responsive genes. Collectively, our findings suggest that OsMSR3 played an important role in regulating Cu tolerance in plants and improved their tolerance to Cu stress through enhanced activation of antioxidative defense mechanisms and positive regulation of ABA-responsive gene expression.

“…Increased concentrations of heavy metals are seriously threatened by soil pollution [1][2][3][4]. Copper (Cu) is an essential plant micronutrient of various heavy metals requiring normal growth and body development [5][6][7][8]. Cu being a micronutrient, cell wall metabolism, nitrogen fixation, protein synthesis, and many other processes in both physiology and biochemistry play a very important role [9][10][11][12].…”

Copper (Cu) is an important micronutrient for a plant’s normal growth and development. However, excess amount of Cu in the soil causes many severe problems in plants—which ultimately affect crop productivity and yield. Moreover, excess of Cu contents causes oxidative damage in the plant tissues by generating excess of reactive oxygen species (ROS). The present experiment was designed to investigate the phytoextraction potential of Cu, morpho-physiological features and biochemical reaction of jute (Corchorus capsularis L.) seedlings using ethylenediaminetetraacetic acid (EDTA) of 3 mM under different Cu levels (0 (control), 50 and 100 μM) in a hydroponic nutrient solution (Hoagland). Our results showed that elevated Cu rates (50 and 100 μM) in the nutrient solution significantly reduced plant height, fresh and dry biomass, total chlorophyll content and gaseous exchange attributes in C. capsularis seedlings. As the concentration of Cu in the medium increased (50 and 100 μM), the level of malondialdehyde (MDA) and oxidative stress in C. capsularis seedlings also increased, which could have been controlled by antioxidant activity in particular plant cells. In addition, rising Cu concentration in the nutrient solution also increased Cu uptake and accumulation in roots and leaves as well as affected the ultrastructure of chloroplast of C. capsularis seedlings. The addition of EDTA to the nutrient solution significantly alleviated Cu toxicity in C. capsularis seedlings, showing a significantly increase in plant growth and biomass. MDA contents was not significantly increased in EDTA-induced plants, suggesting that this treatment was helpful in capturing ROS and thereby reducing ROS in in C. capsularis seedlings. EDTA modification with Cu, although the bioaccumulation factor in roots and leaves and translocation factor for the leaves of C. capsularis seedlings has significantly increased. These results indicate that C. capsularis has considerable potential to cope with Cu stress and is capable of removing a large quantity of Cu from the Cu-contaminated soil while using EDTA is a useful strategy to increase plant growth and biomass with Cu absorption capabilities.

“…The increase in the negative charge of the clay can increase the cation absorption capacity in the soil. Furthermore, there will be a process of deposition of metal ions in the soil solution into unavailable forms and will reduce the effect of heavy metals absorbed by plants [39,40]. The mobility and availability of heavy metals depends on the method and strength of heavy metal fixation by soil components, especially by clay fractions [39][40][41].…”

Cadmium (Cd) is a heavy metal that is prohibited in food products. In the long term, consumption of food containing Cd can cause cancer (it is a direct carcinogen in humans). Poor management of the Serayu watershed has resulted in pollution of the surrounding land. Meanwhile, trust in management must be built within the framework of trade in the Industrial Era 4.0, which is developing continuously in world trade relations. This study aimed to obtain information on the distribution of Cd in agricultural soils in the middle of the Serayu watershed in March-August 2017. A total of 220 soil samples were taken using the GRID method, and the analysis of Cd concentration was determined by atomic absorption spectrofotometry (AAS). The results showed that Cd was detected in 142 soil samples in the range of 1.0-<1.5 mg kg−1 and detected in the range of 0.5-<1.0 mg kg−1 in 78 soil samples. The results were non-normally distributed with a clustered distribution pattern. The average value of the distribution of Cd in agricultural land in the middle of Serayu watershed was 1.21 mg kg−1, and the highest Cd concentration was 2.18 mg kg−1. The Cd concentration in the middle of the Serayu watershed is classified within the safe category because the concentration is still below the critical Cd threshold value of 3-8 mg kg−1.
