Not logged in However, certain reports focused largely on physiological parameters and yield, and there is still a lack of understanding on the mechanisms surrounding plant-HM interactions.The Research Topic aims to address these aspects related to plant-HM interaction in different plant species. Even though heavy metal tolerance in plants through microbial remediation has been investigated for many years, there is still considerable interest in extensive studies on plant–microbe–metal association due to their direct effects on enhanced biomass production and heavy metal tolerance (Glick, 2003; Taj and Rajkumar, 2016; Hansda and Kumar, 2017).

Microalgae, the primary producers in aquatic ecosystems, are highly susceptible to heavy metal contamination. The prolonged application of large amount of fertilizers and pesticides has resulted in heavy metal accumulation in vegetable gardens. In this review, we discuss the sources of Cd pollutants, Cd toxicity to plants, and mechanisms of Cd uptake and redistribution in plant tissues.

Although many metal elements are essential for the growth of plants in low concentrations, their excessive amounts in soil above threshold values can result in toxicity. In addition, plants accumulate metal ions that disturb cellular ionic homeostasis. In other species, HMs may accumulate in roots, and much less is translocated to aerial parts like shoots, leaves, etc. Adv Appl Microbiol 49:111–142, Aydinalp C, Marinova S (2003) Distribution and forms of heavy metals in some agricultural soils.

They reduces productivity, bring stunting in growth and loss in chlorophyll (chlorosis) and protein contents in higher aquatic plants These metals are incorporated permanently in plants and then are passed on to animals and human beings. 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). The metal transporters involved in Cd transport within plant tissues are also discussed and how their manipulation can control Cd uptake and/or translocation. As such, heavy metal toxicity can have several consequences in the human body. Collection folkscanomy_academic; folkscanomy; additional_collections Language English.
