“…In accordance with our results, a small biostimulation of germination by low Cd concentrations was reported (Lefèvre et al 2009). These maybe possible alerts since the biostimulation could be the early cause of hormesis (Baderna et al 2015) or attributed to the stimulation of cell activities through improved ROS signaling (Gapper & Dolan 2006).…”

In this work three heavy metals: cadmium (as CdSO4), cobalt (as CoCl2) and zinc (as ZnSO4), were used to determine and compare their toxicity towards two subspecies of barley (Hordeum vulgare subsp. vulgare L. and Hordeum vulgare subsp. distichum L.), focusing on seeds germination, seedlings growth, and cytological parameters. The results indicate that the effect of these heavy metals depends on the metal kind, the metal concentrations and the plant subspecies. Generally, in the case of H. vulgare, the heavy metal salts understudy did not influence significantly seed germination and seedling growth parameters. However, these metal salts influence significantly these parameters for H. distichum. The cytological test showed significant decrease (p < 0.05) in the mitotic index among the increase of the heavy metal concentrations when evaluated with the control for H. vulgare and H. distichum. Consequently, H. vulgare seemed to be more tolerant of the increase of the three heavy metals concentrations than H. distichum.

“…The hazardous heavy metals being commonly used nowadays include arsenic (As), lead (Pb), mercury (Hg), cadmium (Cd), chromium (Cr), copper (Cu), and nickel (Ni) . Mercury is the third most critical heavy metal and causes lethal effects in metabolic and physiological mechanisms of humans, animals, and plants . Mercury compounds have hazardous effects on the nervous, digestive, cardiovascular, and immune systems, to the lungs, kidneys, skin, eyes, and gastrointestinal tract in humans .…”

“…Bacterial genes involved in mercury resistance are well-organized and -characterized into genetic elements known as mer operons. The Gram negative bacterial mer operons contain a broad spectrum structural gene merE that encode a CH 3 Hg +1 and Hg +2 detoxification system. This system involved in transportation of mercury ions across the cell membrane [8].…”

Mercury resistant (Hg ) bacteria were screened from industrial effluents and effluents-polluted rhizosphere soils near to districts Kasur and Sheikhupura, Pakistan. Out of 60 isolates, three bacterial strains, Bacillus sp. AZ-1, Bacillus cereus AZ-2, and Enterobacter cloacae AZ-3 showed Hg-resistance as 20 μg ml of HgCl and indole-3-acetic acid (IAA) production as 8-38 μg ml . Biochemical and molecular characterization of selected bacteria was confirmed by 16S ribotyping. Mercury resistant genes merA, merB, and merE of mer operon in Bacillus spp. were checked by PCR amplification. The merE gene involved in the transportation of elemental mercury (Hg ) via cell membrane was first time cloned into pHLV vector and transformed in C43(DE3) Escherichia coli cells. The recombinant plasmid (pHLMerE) was expressed and purified by nickel (Ni ) affinity chromatography. Chromatographic techniques viz. thin layer chromatography (TLC), high performance liquid chromatography (HPLC), and Gas chromatography-mass spectrometry (GC-MS) confirmed the presence of Indole-3-acetic acid (IAA) in supernatant of selected bacteria. The strain E. cloacae AZ-3 detoxified 88% of mercury (Hg ) from industrial effluent (p < 0.05) after immobilization in Na-alginate beads. Finally, Hg-resistant and IAA producing bacterial consortium of two strains, Bacillus sp. AZ-1 and E. cloacae AZ-3, inoculated in mercury amended soil with 20 μg ml HgCl resulted 80, 22, 64, 116, 50, 75, 30, and 100% increase as compared to control plants in seed germination, shoot and root length, shoot and root fresh weight, number of pods per plant, number of seeds and weight of seeds, respectively, of chickpea (Cicer arietinum L.) in pot experiments (p < 0.05).

“…For example, cereals, rice, fruits and vegetables were adversely affected by As, including germination inhibition, root elongation suppression, and biomass decrease. Particularly, phytotoxicity of As alone and in mixture was varied because of interactive effects (Badema et al, 2015). In addition, some symptoms are observed in human bodies under acute and chronic exposures, such as burning and dryness of mouth and throat, dysphasia, colicky abnormal pain, projectile vomiting, profuse diarrhea, and hematuria under acute exposure, while disturbance of respiratory, gastro-intestinal, cardio-vascular, nervous and hematopoietic systems under chronic exposure (Ratnaike, 2003;Jain and Ali, 2000;Bissen and Frimmel, 2003).…”
