Chromium was accumulated more in roots followed by shoots with increasing Cr(VI) treatments (0-4 ppm). In the presence of excessive oxygen, chromium (III) oxidizes into Cr (VI), which is highly toxic and more soluble in water than are other forms. Since plants lack a specific transport system for Cr, it is taken up by carriers of essential ions such as sulfate or iron. industries including metallurgical, electroplating, production of paints and The ever-increasing industrial activities over the decades have generated high toxic metal such as chromium (Cr) that hampers the crop productivity. regulated, 21 down-regulated, and 2 were newly induced. To understand the behavior of Burkholderia xenovorans in arsenic-contaminated environments regarding the expression and function of arsenic-resistance genes in this multi-replicon bacterium. poorly developed roots and necrotic lesions. Toxicity of chromium in plants is connected with the enhanced ROS formation and oxidative stress development resulting in the intensified protein modification, lipid peroxidation, and DNA damage.

Under Cr(VI) stress, AsA content increased, 2–11) and are synthesized from glutathione (GSH) by, ). These methods are proposed for the management of toxic heavy metals from soil. The, most readily available form of N to plants is nitrate (NO, Nitrate reductase (NR) is a key enzyme involved in the, Cr(VI) stress concentration of protein nitrogen decrease, thereby suggesting its interference with N uptake and, assimilation. Over 95% of economically viable chromite ores are situated in the southern part of Africa.

It further describes detoxification mechanisms and the resultant biochemical and physiological changes in plants. In the fruits, Cr treatment had no effect on Fe, Mn, Cu and Zn contents. Cr toxicity in plants is observed at, multiple levels, from reduced yield, through effects on leaf, and root growth, to inhibition on enzymatic activities and. In August 1975 it was observed that underground drinking water in Tokyo near the chromium (VI))-containing spoil heaps contained more than 2000 times the permissible limit of chromium. Cr(III) has also been reported to inhibit root growth. Chromite mining activities are indispensable for production of goods and services. Moreover, fertilizers containing 0.43 % Cr(III), ).

For example, AM fungi protected tree, suggesting ameliorating potential of AM fungi. The diverse Cr-resistance mechanisms displayed by microorganisms, and probably by plants, include biosorption, diminished accumulation, precipitation, reduction of Cr(VI) to Cr(III), and chromate efflux. detachment of the cell wall from the plasma membrane.

This may serve as an indicator of chromium pollution. Topological analyses showed 4 transmembrane domains in these HMA3 homologs positioned similarly in terms of cytoplasmic and non-cytoplasmic regions along with ~22-28% -helices, ~22-28% extended strands, and ~50% random coils. The different Cr(VI) concentrations changed chlorophyll (chl) content differently. Total inhibition of germination of seeds was observed at 300 mg/1 concentrations.

ACS Symposium. These findings may be useful for scheming a mitigation strategy for chromium toxicity. Cr(III) and Cr(VI) phytoremediation, by phytostabilizing. In contrast, some of the heavy metals (Pb, Cd) are highly toxic to plants hampering photosynthesis, nutrient uptake, and yield in plants. These findings may provide essential background to perform wet-lab experiments to understand the role of HMA3 in metal homeostasis. The toxic properties of Cr(VI), originate from the action of this form itself as an oxidizing, agent, as well as from the formation of free radicals during. While copper and chromium were also accumulated mainly in roots and were 3 mg kg −1 and 900 mg kg −1 , respectively, at 10 mg L −1 in external solution. electron transport chain in mitochondria isolated from root, inactivation was noticed in NADH: cytochrome, activities, and cytochrome oxidase was the most suscepti-, content in roots and shoots, and an increase in seeds of, NADPH-dependent superoxide production and the activity, of NADPH oxidase and decreased the activity of NADH-, membrane vesicles, thereby suggesting interference of Cr.

The ameliorative effects were studied in terms of Cr uptake, grain yield, antioxidative defense system parameters (viz. In contrast, an active uptake of both Cr, ). Various important parameters were studied which should be studied while investigating chromium toxicity in agricultural crops. The tanning industry is one of the major users of chromium (III) salts. In the current scenario of the environment, chromium contamination is changing very fast and creating problems for the scientist in developing better yielding variety under chromium toxicity.

InBacopa monnieri andScirpus lacustris accumulations of 1600 and 739 μg g-1 dw Cr, respectively, have been reported when exposed to 5 mg L-1 Cr for 168 hours in solution culture. A blend of pictorial and tabular data are provided to enhance understanding of the relevant information being conveyed. The toxicity of metal differs with the type of metal elements.

Mining is an activity that generates a large amount of waste, producing about 65 billion tons annually; fifty-one billion tons is waste rock, and 14 billion tons, already stored globally, are particles with less than 120 μm, which are named “mine tailings” which are deposited on land.

The cis-acting elements of HMA3 genes were projected to be involved with stress response, anaerobic induction, and light responsive regulation in plants. At higher concentration (4 ppm), Cr stress decreased the grain yield (45-50%) as compared with controls. Human activities are increasing heavy metal contamination in agricultural soil, water, and air which are reaching plants directly or indirectly which in-turn causing major loss of agricultural crops and deficiency of food.
