Heavy metals reduce grain yields and dry weight of wheat plants, with Cadmium (Cd) having the highest effect and Chromium (Cr) the lowest. Plants have evolved diverse strategies to tolerate heavy metal toxicity. Bot Stud 55:1–12, Visioli G, Vincenzi S, Marmiroli M, Marmiroli N (2012) Correlation between phenotype and proteome in the Ni hyperaccumulator Noccaea caerulescens subsp. 2009). The chromatin material was highly condensed and some of the cortical cells showed disruption and dilation of nuclear membrane in presence of 7.5 mM zinc. In: Alloway BJ (ed) Heavy metals in soils. Rice consumption is a major source of Cd intake for human. However, some plant species can tolerate higher levels of toxic metals in their roots and shoots. Being a natural resource, metals have been used by mankind from ancient times. In this review, we discuss the sources of Cd pollutants, Cd toxicity to plants, and mechanisms of Cd uptake and redistribution in plant tissues. Among the abiotic stresses, toxic metal stress is one of the major threats to plant growth and development. Exposure to heavy metals such as nickel, cobalt, cadmium, chromium, lead and copper can cause potential adverse effects to the environment due to its high metal toxicity effects. For example, some plant species limit HM absorption through avoidance.

Heavy metal poisoning is rare, but it can have lasting effects on your health. The evaluation of the toxicity and stress caused by heavy metals on plants is very important part of the phytoremediation research. Large parts of agricultural soil are contaminated with heavymetals by natural and anthropogenic activities. Several physiological parameters can be used to assess the heavy metalinduced stress such as germination, plant growth and biomass production, photosynthetic pigments, antioxidant enzymes or antioxidants. EPA, Washington, Hirayama T, Kieber JJ, Hirayama N et al (1999) RESPONSIVE-TO-ANTAGONIST1, a Menkes/Wilson disease-related copper transporter, is required for ethylene signaling in Arabidopsis. HMs such as Cd, Cr, Pb, As, Co, Cu, Ni, Zn, Mn, etc. Upon entry into plants, HMs can alter normal growth and development by distorting nutrient balances, physiological and metalloenzyme activities, and damage cell ultrastructure. Abedin et al. Plants have their own resistance mechanisms against toxic effects and for detoxifying heavy metal pollution. Plants have also evolved with an extensive and 2. Part of Springer Nature. The toxicity of four potentially toxic trace elements (Cu, Ni, Pb and Zn) to Annual Atriplex (A.hortensis and A. rosea) was examined to determine if this plant showed sufficient tolerance to be used tophytoremediate soils polluted with these heavy metals. The general mechanism involved in heavy metal‐induced toxicity is recognized to be the production of reactive oxygen species resulting oxidative damage and health related adverse effects. These include substances such as DMSA, DMPS, and EDTA. Over 10 million scientific documents at your fingertips. Heavy metals (HMs) are described as elements with metallic properties having an atomic number higher than 20. Heavy metal toxicity can either be acute or chronic effects. Plant Cell Physiol 46:1809–1818, Kim Y-N, Kim J-S, Seo S-G et al (2011) Cadmium resistance in tobacco plants expressing the MuSI gene. The metal transporters involved in Cd transport within plant tissues are also discussed and how their manipulation can control Cd uptake and/or translocation. Cell 97:383–393, Hohl H, Varma A (2010) Soil: the living matrix. The toxic effects of heavy metals on aquatic plants include cell membrane structural damage; inhibitions of respiration, photosynthesis, growth, and development processes; and toxicity to genetic materials.

Water Air Soil Pollut 226:1–12, Mehes-Smith M, Nkongolo K, Cholewa E (2013) Coping mechanisms of plants to metal contaminated soil. The cell wall can act as a biosorbent to alleviate toxic effects of heavy metals [48,49]. The toxicity and endocrine-disrupting effects are documented for As , ], Cr [, , , , , ], Ni [59, 60], Pb , and Co [62, 63]. Introduction. Chapman and Hall, London, Jentschke G, Godbold DL (2000) Metal toxicity and ectomycorrhizas. In general, heavy metals toxicity is induced when they reach a critical concentration value and especially when they are at their available form (Nagajyoti et al., 2010).

In other species, HMs may accumulate in roots, and much less is translocated to aerial parts like shoots, leaves, etc. It is primarily the avidity of heavy metals for natural metal-binding agents which determine their toxicity.
