Trends Plant Sci 14:43–50, Sherameti I, Varma A (2015) Heavy metal contamination of soils: monitoring and remediation. Exposure to heavy metal toxicity has become a major limiting factor in the growth of crop plants, affecting the sustainability of agricultural production (Lin et al., 2005; Molas 2002). The major change was seen in the nucleus of the root tip cells due to zinc toxicity.

The effect of heavy metal toxicity on the growth and development of plants differs according to the particular heavy metal for that process. Being sessile, plants adopted a range of strategies for sensing and responding to nutrient availability to optimize development and growth, as well as to protect their metabolisms from heavy metal toxicity. (2018). Since plants lack a specific transport system for Cr, it is taken up by carriers of essential ions such as sulfate or iron.

New knowledge on microbial reaction to metal contamination and the relationship between bacterial, archaeal, and fungal resistance to metals has broadened our understanding of metal homeostasis in living organisms. In plants, heavy metals hinder the normal metabolism by disturbing physiological and biochemical process (Ackova 2018). Cadmium (Cd) is a highly toxic heavy metal for both animals and plants. We welcome Original Research, Reviews, and Mini-Reviews that fall within this area. As a result, progressive chlorosis, necrosis, and decreased protein content are typical signs of heavy metal toxicity to plants [1, 12–15].

In each site, we examined the effect of proximity to road on heavy metal concentrations (cadmium, nickel, lead, and zinc) in four of the most common roadside plant species—Melilotus indicus, Herschfeldia incana, Avena sativa, and Artemisia californica—as well as on soil metal concentrations. Plants have their own resistance mechanisms against toxic effects and for detoxifying heavy metal pollution. The essentials element likewise Fe, Zn, Cu or Mo are required in small quantities but at higher concentrations they may be poisonous for plant growth. Keywords: Heavy metals entering plants can change the autioxidant enzyme activities, induce ROS production, and cause oxidative damage effects. Plants growing on these soils show a reduction in growth, performance, and yield. (2017) A cadmium stress-responsive gene AtFC1 confers plant tolerance to cadmium toxicity. Some metals, like Zinc (Zn), Copper (Cu), Manganese (Mn), Nickel (Ni), Cobalt (Co), and Selenium (Se), are regarded as micronutrients acting as co-enzymes and other functions, while others like Cadmium (Cd), Lead (Pb), Chromium (Cr) and Mercury (Hg) have unknown biological function.
